DIY vacuum pump from a syringe

In this story from the TOKARKA channel, they showed the author’s original idea of how to make a very simple and useful thing – a vacuum pump – from a large syringe in a short time. With its help, you can very conveniently and quickly preserve various products and pump out air from technical mixtures. The power of the vacuum pump allows you to deform a plastic bottle so much as if it had been opened in space, closed and lowered back to earth. You can inflate a balloon without contact or increase the volume of many objects that have air inside.

In order to make a valve, we need an elastic band from a dropper. All plastic inserts must be removed. Now we cut this part into two parts, they will be parts from the valve. A rubber tube, which is smaller, is inserted into the nose of the syringe and must be compacted with any convenient rod. Inside is a ball from a bearing. A bullet from an air pistol in cans will also work very well.

The release valve is completely ready and air can enter the syringe, but cannot leave it. The last thing left to do is the release valve. The authors heated the urticaria needle and pointed it into the hole through which air would escape. This piece of rubber tube was later secured with a drop of superglue. The pump is completely ready.

For convenience, a thick-walled PVC tube will be used. It won't work with a dropper because the vacuum will flatten it. If you make holes in the lid of a container, such as a jar, for the spout of a syringe, the tube is not needed at all.

A great demonstration of how atmospheric pressure works. The air inside the bottle is discharged, or rather a vacuum is formed. Atmospheric pressure crushes it. Absolutely the same thing happened to her if she was lowered to the bottom of the ocean.

If the hole through which the air is pumped out is soldered or sealed with a piece of tape, such a sandwich can be stored for a very long time. In the supermarket there are products packaged this way. If you place a marshmallow in a vacuum chamber, it will inflate just like this ball.

The master needs the camera for other purposes. For example, for degassing epoxy resin, that is, the formation of air bubbles from it. If you degas the gypsum solution, the cast parts are of very good quality. With a smooth surface. The author of the video came up with the design of this wonderful super simple valve for a vacuum pump on his own.

On women's and men's forums you can often see topics dedicated to how to make a penis pump with your own hands. What kind of device is this? Why is it needed? What is required to prepare it? Let's take a closer look at these issues.

Indications for use

A pump (or vacuum pump) is a modern cylindrical device designed to improve the quality of sexual life.

There are several indications for its use:

The need to increase the volume or length of the penis.
Partial or complete absence of erection.
Insufficient degree of elasticity of the penis during sexual intercourse.
Impotence.

The principle of operation is that the device creates high pressure in the groin area of a man. This leads to increased blood flow, stretching of the cavernous bodies and, accordingly, to an enlargement of the penis. Ready-made equipment can be purchased at a price of 3,000–5,000 rubles. It is much more profitable to create a vacuum pump for the penis with your own hands.

Manufacturing of a liquid ring or low vacuum pump

When thinking about how to make a vacuum chamber or press, the vacuum in which provides the required pressure on the workpiece, you should keep in mind that to equip them you will need more powerful pumping equipment. Such equipment, in particular, is a liquid ring or low-vacuum pump, which creates 90–95% vacuum. In order for devices of this type to create an even greater vacuum, the water used in them as a working fluid is replaced with a liquid medium characterized by a higher boiling point.

Main elements of a vacuum liquid ring pump

Devices that are optimally suited for a vacuum-type press operate on the principle of a centrifugal pump. The main working body of the latter is a wheel with blades. When such a wheel rotates together with water supplied to the pump, a low pressure area is created in the central part of the working chamber, which promotes the suction of air through the inlet pipe.

Drawing of a vacuum liquid ring pump

A do-it-yourself vacuum chamber (like all components for a vacuum-type press) can be made in a home workshop equipped with all the necessary equipment and tools.

Preparing to create. Flask

To prepare a manual pump for penis enlargement with your own hands, you will need three basic preparations.

The flask is a device in which the penis will be placed during “training”. It is recommended to purchase a cylindrical beaker from a pharmacy or medical supply store. If there is no opportunity to buy it, then you can use improvised analogues:

The outer part of a large syringe, freed from the needle and inner rod.

Empty bottle. It requires making a hole for the penis on one side and a small cut for the tube on the opposite edge.

Many men believe that they can use an aerosol can of the right size. But this is not recommended due to environmental factors.

When creating a flask, you need to remember that its size must correspond to the length and volume of the penis. Otherwise, the man will experience discomfort. Before manufacturing, it is necessary to check the integrity of the structure; there should be no cracks or other damage that could lead to injury. There should be no corners or roughness on the surface of the flask. It is worth remembering to ensure tightness, without which the desired effect will not be achieved.

Liquid ring pump

Anyone who is willing to spend a little more labor and money on fees for a familiar turner and welder can take on the manufacture of a vacuum pump with a liquid piston (the second name for water ring-type units). Such a pump is a pipe in which an impeller with radial blades is installed with some displacement relative to the axis.

The pump is partially filled with water, and the impeller shaft is driven by an electric motor.

At the same time, the impeller blades also impart a rotational movement to the liquid, as a result of which it is pressed by the resulting centrifugal force against the walls of the housing and forms a rotating ring.

Between the liquid ring and the rotor (impeller) bushing, a crescent-shaped cavity is formed (recall that the wheel is mounted eccentrically), which plays the role of a working chamber.

The blades divide it into several parts, and their volume either increases or decreases as the wheel rotates. At the beginning of the cycle (increase in volume), the cell sucks in the pumped gas, at the end (decrease in volume) it is compressed, that is, it is pumped.

In this case, the heat released in the compressed gas “goes” into the water, so that its temperature remains almost constant (isothermal compression). The water gradually heats up more and more, so it has to be changed periodically.

Water enters the pump from the tank through the hydraulic seal of the rotor shaft or through the suction pipe. Then it, like the compressed gas contained in it, is discharged through the outlet (discharge) openings.

As you can see, the liquid ring pump is designed quite simply. In addition to the materials (pipes for making the housing, end caps and shaft, steel sheet for making the wheel, blades and tank), you will need bearings and an electric motor. The impeller is installed so that it does not come into contact with the housing and end covers. Thus, there is no friction between any parts of the pump, which means there is nothing to wear out.

Water ring pump

Pressing of bearings is carried out using a special tool - a puller. You can also make it yourself. The required force in any puller, regardless of its design, is created by tightening the thread. The simplest option is two plates with holes for the studs. We rest one plate against the end of the shaft, and install the other behind the bearing.

Having inserted the studs into the holes of the plates, you need to tighten the nuts on them one by one and gradually, as a result of which the second plate will be attracted to the first, and at the same time press the bearing onto the shaft. Before starting the operation, it must be lubricated with lithol.

A liquid ring pump can pump out gases with a high content of dust, sand or moisture without consequences. In this case, all the debris remains in the water, that is, in parallel with pumping, gas filtration occurs. However, during prolonged operation under such conditions, the ends of the impeller may wear out. In this case, it will be enough to restore the required clearances by installing gaskets between the housing and the end covers.

The liquid ring pump belongs to the oil-free category. This means that its working mechanism does not require lubrication. Only a small amount of it needs to be injected into the bearings. High precision in the manufacture of individual parts is not required.

Creating a seal

An important detail when creating a pump for penis enlargement with your own hands is the seal. It is necessary to create a vacuum in the flask.

As a seal, you can use a regular clamp, which will later cover the pump. If there is an old vacuum cleaner in the house that does not work, then you can use an electric pump from it.

Important. The seal, like the flask, must correspond to the width of the genital organ. You first need to measure it with a centimeter. If you make it small, then discomfort will occur during the exercise; if it is large, then a vacuum will not be created, and accordingly, the desired effect will not be achieved.

DIY vacuum pump from a hospital syringe

In the previous section, we learned how to make a very practical vacuum pump, but at the same time we were left without a conventional pump, which not everyone is ready to accept.

If you cannot afford such luxury or your religion prohibits you from disassembling car pumps, use a regular medical syringe as a pump.

For just a few rubles you can buy it at any pharmacy.

We begin to master the secret technology:

In addition to the syringe, prepare two plastic check valves and a short silicone tube of such a diameter that the valves fit tightly into it.
Use a needle or awl to make a small hole in the middle of the silicone tube. Its diameter should not be too small so that the nozzle from the syringe can be pushed into the hole, but not too large so that the nozzle fits as tightly as possible.
Insert the syringe into the finished hole.
Now you need to insert a check valve into the silicone tube at both ends. One is installed in such a way that it lets air into the tube, the other, on the contrary, must release air from it. We will call the first valve the suction valve. A rigid tube must be attached to it, through which the vacuum pump will be connected to a container, bag of clothes or other object.

By moving the syringe piston back and forth, we, although not immediately (the volume of the syringe is not too large), will be able to create the necessary vacuum.

A device such as an uninterruptible power supply is necessary to insure devices during a power outage. Uninterruptible power supply for a heating pump - features of choosing a device and the cost of the unit.

Let's look at the operating principle of a heat pump for heating a house here. How effective is this system?

Most often, circulation pumps are purchased for private homes, and if in your village there is no service nearby for the maintenance of such devices, then you need to master some types of repairs yourself. Here https://microklimat.pro/otopitelnoe-oborudovanie/otopitelnye-pribory/remont-cirkulyacionnogo-nasosa-svoimi-rukami.html some instructions and tips for repairing pumps are given.

Creating a handle

The last component needed to create your own vacuum pump for penis enlargement is a handle. Ideally, you should disconnect the hose from the old-style tonometer. Using a bulb, you can easily pump out excess air from the flask.

It is worth noting that a similar device for creating a vacuum in a closed container is sold separately in some medical supply stores. It is ideal for realizing your plans.

It will be more difficult to use a hose that fits onto the base of a bottle or syringe. The air will need to be pumped out by mouth, syringe or small pump, which will require considerable effort.

Modernization of the cuff pump

You can make a vacuum pump for pumping out air with your own hands from any cuff device. Even bicycle devices are suitable for these purposes. Of course, it is better to take a car pump, because improving it will be much less hassle.

Step-by-step manufacturing instructions:

Spin up the car device.
Remove the cuff and turn it the other way around.
Reassemble the device in reverse order. The difference is that the cuff is reversed.
At the inlet of the pump, where the hose is located, with which air is pumped out, screw on the check valve. The latter must function by passing air flow from the vessel to the device. There should be no movement of the air mass in the opposite direction. The check valve can be purchased separately or taken from the aquarium compressor. Immediately before installation you need to blow into it. Screw the side that will not let air through to the pump, and the other to the tube. It should be noted that the device is quite sufficient to meet household needs, but it is not suitable for creating a deep vacuum due to its low power.

Preparing for work

The penis is the most delicate part of the male body, consisting of many soft tissues. It is quite difficult to damage it. Therefore, before you start figuring out how to make a penis pump with your own hands, you need to start preparing each part for assembly.

First of all, you need to examine the surface of the seal and flask. There should be absolutely no sharp corners, cracks or rough surfaces. Any, even the smallest unevenness can cause irreparable harm to health.

The second important point is the correct choice of material. It is important that it does not cause an allergic reaction on the skin. Otherwise, instead of the elasticity of the penis, the man will get irritation and itching.

The third detail is the mandatory processing of the main mechanisms. It is necessary to wash the seal and flask with a sterile solution or soapy water. Next, they need to be dried and further treated with alcohol.

Having ensured that all components are sterile and safe, you can proceed to the main stage - assembling the device.

Build process

So, all the parts are ready for work, now you can move on to the main question, which is how to assemble a penis pump with your own hands. This procedure consists of several basic steps:

You should take a clean flask in your hands and make a small hole in the upper part, place a tube in it, which will act as a valve. It is necessary that it tightly closes the hole and does not allow air to pass through it.

A clamp must be attached to the base of the flask. It should be the same size as the base of the penis. Additionally, you can cover it with soft fabric for more comfortable use. A sealant must be used as a connecting element to connect parts. It is recommended to apply it in a thin layer.

The DIY penis pump is ready. But don’t rush to try it out. It is necessary to allow the product to dry completely for 2-3 days, only after that you can begin to correct your manhood.

Applications of hand air pumps

To solve simple problems associated with creating a shallow vacuum, any device for pumping air is suitable - a manual or foot-operated car pump, or even a medical syringe. Using the latter as an example, we will show the assembly of a simple vacuum pump. For work you will need the following materials:

syringe with a capacity of 10-20 ml;
plastic check valve – 2 pcs.;
transparent tubes from the IV;
tee.

Assemble the manual air pumping apparatus in this order:

Cut 3 pieces 5-6 cm long from the dropper tube.
Place the pieces on the tee outlets and connect the syringe to the middle one.
Install check valves at the ends of the 2 remaining tubes so that the arrows on the body point in different directions.
To the valve outlet whose arrow is directed towards the syringe, connect the tube leading to the evacuation object. You can check the operation of the pump with a liter plastic bottle.

The principle of operation is as follows: when you pull the piston, air passes through the valve on the bottle side, the second line is blocked. After pressing the rod, the valve of the first tube no longer lets air in, but the second one is open. If you work intensively with the piston, a vacuum will quickly form inside the bottle, as shown in the video:

More productive manual units are made from various piston attachments. A regular pump designed for inflating car tires will do. To convert a simple device into a vacuum pump, follow the instructions:

After unscrewing the ribbed nut on top of the body, remove the rod with the cuff.
Using a 10 mm wrench, unscrew the cuff mounting nut and move the element with the skirt up, as shown in the photo. Tighten the fasteners back.
Assemble the device and install a check valve on the supply hose.

After the modification, the pump will draw air through the main hose and exhaust it through a hole in the housing. If you need to inflate your car wheels, it is easy to return the cuff to its original position. How to make a vacuum pump from a small bicycle pump, watch the video:

Important points

The size of a man's manhood matters when building relationships. That is why representatives of the stronger half of humanity often decide to create a pump with their own hands to increase the length of the penis. Many “masters” make mistakes at the manufacturing stage. It's worth talking about some important points.

Many men have been injured due to improperly sized seals. When a vacuum was created by the device, the base of the penis was damaged or the testicles were sucked into the flask. It is very important to measure the width of the penis and make the o-ring 0.5 cm larger.

Advantages

You can create a penis pump in width and length with your own hands in exactly the same way, since the principle of its operation is to increase blood flow and stretch the corpora cavernosa. Why is it worth making it yourself and not buying it in a store?

Of course, only for the purpose of saving. If the finished product costs more than 3,000 rubles, then you can create a device with the same method of operation absolutely free from improvised means or spend a small amount on the main components - up to 500 rubles.

Flaws

There are more disadvantages to creating a homemade device than advantages. First of all, they are associated with the labor intensity of the process. Not every person will be able to create a safe device that allows them to achieve the desired effect, which would meet sanitary and hygienic requirements and would be suitable in size.

The second disadvantage is the aesthetic appearance. The finished device looks much more attractive.

And, of course, the operating principle is a little more complicated. In a sex shop you can buy an automatic mechanism. You just need to press a button and you can enjoy the process. At home, you can only create a manual device.

Terms of use

Separately, it is worth mentioning the issue related to the use of a correction pump for the penis:

The penis must first be treated with lubricant.
Carefully insert it into the flask through the seal.
You should pump out all the air from the container using a bulb.
The hose must be secured with a clothespin to create a fixation.
The member should remain in the flask for 30-40 minutes.

Important: any diseases of the reproductive system are contraindications. If discomfort occurs during operation of the device, you should unhook the clothespin from the hose and carefully remove the flask.

Didn't nature reward you with a big penis? Over time, has he become less elastic than in his youth? Did you lose your erection or did the first signs of impotence appear? If such problems arise, then you should think about how to create a penis pump with your own hands. A simple device will allow a man to always stay in shape and please women at no cost.

A vacuum pump for penis enlargement is an innovative product that is based on applying pressure to the penis.

The device gives quick but short-term results . The real increase occurs after systematic and long-term use.

The device is bought in specialized stores or assembled from improvised materials. With the right approach, a device similar to conveyor pumps is obtained.

Vacuum pump from a refrigeration compressor

Let's look at how to make a vacuum pump with your own hands from a compressor.
The compressor from an old refrigerator is an almost finished vacuum pump.

But in order to finally transform it into one, you will have to remember the skills of a home craftsman.

Here's what to do:

Use a hacksaw to cut off the top of the compressor.
Remove the motor suspended on springs and connect the suction and discharge lines with tubes made of oil-resistant material (sold in car dealerships) with scraps of copper tubes available in the housing.
Now you need to make a cover for the body. The cut top cannot be used for this purpose, since the oil flowing down it will seep out. The new lid should be slightly smaller in diameter than the body so that its edges are inside it. It is recommended to solder it from brass foil, providing stiffeners with an external soundproofing coating made of linoleum. Theoretically, there is no need to equip the lid with a “blowhole”, since if all the tubes are connected tightly enough, the pressure inside the compressor will remain at atmospheric level. However, in case of unexpected depressurization, you should still install something like a breather.
Unlike a liquid ring vacuum pump, this vacuum pump is not oil-free. There is oil inside and its level constantly drops as it is thrown out in the form of mist through the discharge pipe. To control the oil level, it is recommended to equip the pump with a homemade level gauge. It is a part of the transparent body of a ballpoint pen (installed vertically with the cap up), connected to the compressor body with an oil-resistant tube. The cap must be slightly unscrewed to allow air to pass through. For ease of use, you need to scratch transverse marks on the level gauge corresponding to the oil level - minimum and maximum.

The converted compressor must be placed in a box, which is a frame made of 25x25 mm steel angle covered with any sheet material.

To ensure that the housing does not have to be disassembled to check the readings on the oil level gauge, cut a hatch into its side wall. If the pump is located in a poorly lit place, you can also install a light bulb next to the level gauge for illumination.

Since the oil pump does not tolerate moisture and dust getting inside, it is necessary to install a filter in front of the suction pipe. If relatively dry air will be pumped out, it is enough to install a fine air filter for cars of the FT-206 type.

Refrigerator compressor

If it is assumed that the pumped-out medium will have high humidity (for example, when using a vacuum pump to accelerate the evaporation process in the distillation cube), you will have to additionally install a receiver with a sump or some special dehumidifier at the inlet.

An oil filter type FV-6 should be connected to the discharge pipe. It has a plug to drain oil condensate.

It remains to install an excess pressure relief device in the area between the discharge pipe and the oil trap filter. If you turn on the engine with excess pressure on the discharge line, it will take too long to spin up and the starting winding will burn out. The best solution is to install an electro-pneumatic valve through a tee and connect it in parallel with the engine.

When the pump is turned off, the valve will open. When switched on, voltage will be applied to its coil and it will close, so that all the forced air will flow through the oil trap.

The Vilo brand is known throughout the world. Wilo pumps: technical specifications and model overview - read about all this in the article.

Compound

The materials used to make a homemade penis pump are simple. It consists of 4 elements:

The plastic cylinder is the mold into which the penis is placed.
Seal – a rubber bottom with a hole serves to fix the penis.
Tube - air is pumped out of a cylindrical shape through it.
The piston is like in a device for measuring pressure. Serves to form a vacuum, attached to the tube.

By putting the parts together, you get an effective device that solves the problem of insufficient penis size.

Types of fecal equipment

Unlike traditional analogues, which are vulnerable to various types of blockages, fecal equipment can easily cope with wastewater containing solid particles.

The main purpose of a septic tank pump is to pump wastewater

Depending on the installation method and design solution, there are three main types of fecal pumps: surface, submersible and semi-submersible.

Surface-type equipment is used for pumping water from local treatment facilities. They are compact and low cost.

Surface-type devices are capable of pumping out liquid whose inclusion sizes do not exceed 5 mm

Surface pumps are good because they can be placed at a considerable distance from the well (up to 9 meters). In this case, the pump itself remains on the surface, and only the suction pipe is immersed in the drains.

Manufacturers design devices differently. Surface models can be a full-fledged station operating in automatic mode, or a compact unit operating in manual mode.

Water pumps for septic tanks are divided into two groups:

Non-self-priming - lift liquid from a depth of up to 7 meters. In this case, the suction hose is completely filled.
Self-priming - capable of lifting wastewater from a depth of up to 8 meters. But the suction hose does not fill with water.

The operation of most devices of this type is based on centrifugal force. But still, the so-called vortex devices are most in demand. Although they work only at shallow depths, they are famous for their greater power with minimal noise during operation.

If you focus on the type of engine, then there are gasoline, electric and diesel devices

A surface pump can only be installed permanently indoors. If there is no suitable room near the septic tank, experts recommend making a pit or caisson near the tank, into which to place the unit.

Submersible models are designed to pump out household waste containing large long-fiber impurities from storage tanks of autonomous sewers.

Submersible models are able to operate uninterruptedly in aggressive environments

Submersible pumping equipment is characterized by high power, which can reach 40 kW, and the ability to pump dense impurities with fractions up to 4 cm in size. Such a device cannot become clogged, since its flow channels are quite wide. The equipment is made of chemically resistant materials: cast iron, stainless steel.

The main difference between models of this type is the presence of a special float, thanks to which the engine remains above the surface of the water.

Semi-submersible pumps are used for pumping mainly small holes

An electric motor is used as a drive in semi-submersible models. They are characterized by an improved cooling system. The steel body and mechanical end seal reliably protect the device from moisture and destruction.

A significant disadvantage of submersible devices is the small diameter of the flow channels. This significantly limits the possibility of using them when pumping liquids with solid inclusions whose diameter exceeds 15 mm.

How to make a penis pump: description of the assembly process

It will take 30-50 minutes to create a pump at home.

In the bottle, carefully cut out a hole for the penis in the center of the cap. The size corresponds to the width of the erect penis.
On the other side of the bottle we cut a hole for the tube.
We place its edge in the hole and treat it with sealant.

The manufactured pump lasts 2-3 years, not inferior in properties to the conveyor version. The following video describes the self-assembly process of the pump:

Low vacuum unit

It is quite difficult to make it yourself in the absence of a lathe, welding machine and without special skills. A cylindrical body is required for manufacturing. It should contain a shaft equipped with a blade wheel. When water is supplied, the wheel rotates and, under the influence of centrifugal forces, a vacuum will certainly be created in the device.

The mechanism operates using an electric motor. The impeller should not be installed directly in the center. This is necessary so that the gaseous mass is injected and pushed through the system. The disadvantage of such a device is that the liquid that makes the device work constantly heats up and needs to be replaced.

The most common mistakes

Assembling correctly is not a difficult task. Beginners make mistakes in the methods of processing the device, choosing components and exercises.

Mistake #1 – Incorrectly selected seal

Refusal of the seal or incorrect selection of the hole size leads to the suction of the testicles into the cylinder. This should not be allowed, as there is a high risk of injury.

Mistake #2 – The tube is not secured

Mistake #3 – Plastic lid

We construct a vacuum pump with a rubber cover. The plastic rubs and puts pressure on the penis during an erection.

Mistake #4 – Narrow tube

We do not use material with an internal diameter of less than 2-3 mm . It bends and air does not enter the cylinder.

Instructions for use: basic rules

Obtaining a pleasant result accompanied by comfort depends on following the rules and precautions.

Lubricate the base of the penis and the hole in the bottle with lubricant, and insert the penis into the mold.
We pump out the air from the cylinder, the penis begins to erect until a vacuum condition occurs.
For complete fixation , bend the hose and secure it with a clothespin. This way the air won't get back in.

Leave the penis in this state for 30-40 minutes . You can masturbate if you wish.

Harm and contraindications

If the penis enlargement device is used incorrectly harm or injury .

Manufacturers and doctors have developed a list of contraindications.

Tendency to bleed. High pressure in the cylinder increases blood flow, which provokes symptoms.
Combining analgesics with procedures is dangerous. The absence of pain will not let you know when it’s time to stop the process.
Excessive use leads to hematomas and bruises on the penis.
Painful erections are the reason for looking for alternative options to the pump.

The presence of at least one of them is the reason for refusing to use a vacuum pump.

Homemade or purchased

The question of the benefits of creating devices from improvised means is relevant. There are branded models for only $15 . However, the price spread in this category of goods is quite noticeable. Let's analyze all the pros and cons.

Advantages of the factory option

Cost for a simple model - $15.
I produce pumps using strict technology. They do not cause discomfort .
Wide choice: amount, shape, color and method of air injection.
Confidentiality. Ordering from an online store requires delivery in opaque packaging without indicating the contents.

Advantages of a homemade pump

Spend less money.

By assembling the model yourself, you get satisfaction from the design process. Operation will not give such results. The device costs less than a thousand rubles, so it is popular among clients in this market. A homemade pump is used as a “demo version” : assembled, tried. I liked it and bought a store-bought equivalent.

Making a handheld device from a syringe

This mini hand pump is very affordable and anyone can assemble it without any problems.

To make a device from a syringe, you need to prepare:

Hospital syringe, preferably a larger one;
Tee;
A tube the same in diameter as the tee and syringe;
2 check valves.

First, a flexible plastic tube is cut into 3 parts and attached to the tee. A syringe is attached to one tube, and aquarium valves are attached to the other two.

To create a pump from a syringe you do not need to spend a lot of money

You can use aquarium valves of the same diameter as the tube itself.

One valve is inserted for air intake, the other for exhaust. When the piston moves in the syringe, air is pumped out of the container. In the same way, you can pour water from one vessel to a second.
