Gasoline motor pump - we pump water without being tied to an outlet, basic requirements for the device

A gasoline motor pump is a stationary or portable centrifugal pump designed for pumping water. To work with dirty liquids, certain models of units are required. It is recommended to choose models with gasoline engines for these purposes. They can be used anywhere, even remote from the power grid.

The average power of the drive motors that are equipped with gasoline motor pumps for dirty water ranges from 2 to 10 horsepower, which is much more than that of electric devices. This means that motor pumps with an internal combustion engine have significantly greater technical capabilities and can be successfully used to solve a variety of household and business problems.

Operating principle of the pump pump

If there is an electric motor in the motor pump used to provide water to the irrigation system, its maximum distance from the source of electricity is limited by the length of the cable and for this reason its use is possible only in a small area.

Small dimensions and weight do not affect the high performance of the motor pump. Its use allows liquids to be pumped over hundreds of meters, which ensures a high level of demand for many years.

Features and scope of application of gasoline motor pumps

Gasoline motor pumps have found their application in the following areas:

• drinking water supply;
• irrigation;
• hydromelioration;
• firefighting and first responder activities;
• household or communal needs related to draining basements, cesspools and drainage systems.

Advantages of gasoline motor pumps for water:

• independence from power supply;
• high performance;
• good pressure characteristics, allowing you to lift liquid from a depth of up to 8 m;
• reliability of the design, which is not afraid of long-term operation, power surges, “dry” running and other nuances that electric pumps are not immune to;
• guarantee of safety for the user.

The main disadvantage that all gasoline motor pumps without exception have in common is the formation of harmful atmospheric gases after fuel combustion.

Technical capabilities of motor pumps

The most important technical parameters:

• Motor pump performance. This parameter in the technical documentation has the dimension l/min.
• Maximum lift height (pressure, outlet pressure).
• Suction depth expressed in meters.
• Engine power (indicated in kW).
• Diameters of holes at the pump inlet and outlet.

When deciding how to choose a motor pump, you should take into account the pressure, as well as the greatest distance over which liquid can be pumped.

When determining this parameter, a simple formula is used: the maximum height (in meters) of liquid supply, multiplied by 10, gives the maximum possible pumping distance in the horizontal direction.

If you need to choose a motor pump for your dacha, you should take into account the height to which you will have to supply water and the distance from the source to the boundaries of the site.

You should also take into account the fuel consumption of the pump engine. For engines with low power this figure is 2 liters per hour, while more powerful ones can be 4-5 liters.

There are two types of pumps used in pumps: diaphragm and centrifugal.

If the diaphragm is used for pumping heavily contaminated and thickened liquids, then the centrifugal is used only for working with water that does not contain impurities in significant quantities.

Operating rules

In order for the motor pump to operate without failures, it is important to follow the following recommendations for its operation:

• Place the unit strictly horizontally to prevent oil from flowing to one side. In this case, automatic blocking will work.

• Before starting work, pour some water into the chamber . This will prevent dry running. In models with protection, starting “dry” will not happen at all.

First start

After correct installation of the motor pump, you can start the process of pumping out the liquid:

1. Install the suction pipe through the sealing gasket to the suction flange and tighten the nut.
2. Push the suction hose all the way in.
3. Immerse the suction hose in water.
4. Fill the fuel tank with gasoline or a mixture of gasoline and oil (according to the instructions).
5. Fill the pump chamber with water through the opening provided for this purpose.
6. Close the air damper.
7. Move the gas lever to the middle position.
8. Press the carburetor fuel suction lever several times.
9. Repeatedly sharply, but without jerking, pull the starting handle (magneto) towards you.
10. Once the engine is running, fully open the choke in the direction indicated on the installation.
11. Place the throttle lever in idle mode and warm up the engine for 15-20 seconds.
12. Subsequently, use the gas control lever to switch the engine operation to the required mode.

The motor pump is turned off in the reverse order:

1. Move the throttle lever to low gas and the air damper to the middle position.
2. After 2 - 3 minutes of operation, turn off the fuel valve.
3. When the carburetor is completely empty of fuel and the engine stalls, turn the main switch to the off position.

How to properly maintain

Like any technical equipment, a motor pump requires regular maintenance and service.

In order for the unit to work for a long time and properly, it is necessary to regularly carry out the following actions:

• Change of oil . It is necessary to regularly check the engine oil and top it up if necessary. According to the regulations, the first replacement is carried out after 20 hours of operation, then every 100 hours.
• Replacing air filters . According to the manufacturers' instructions for most motor pumps, the filter is replaced every 50 hours.

• Cleaning . After each use, the unit must be rinsed with clean water, especially if contaminated liquids have been pumped. If dirt dries inside the chamber, the motor pump may jam the next time it is started.

What can lead to breakdowns

A motor pump is a fairly reliable unit, but it is better to protect it from certain types of impact.

To prevent the unit from malfunctioning, you need to know what it is afraid of:

• Bumps and falls . Excessive mechanical impact is dangerous for any equipment. Despite the installation of the motor in a protective frame, some parts are in the public domain. If dropped, the fuel tank may be damaged, the hose may fall off, or the inlet ports may become deformed. During falls, oil or fuel may leak out, which will subsequently disrupt the operation of the engine.
• Wind raising dust . The air filter will definitely not like this.

• Rain . Small drops will not harm the motor pump, but it is better not to expose it to strong rain showers. It is also important to ensure that in wet weather the device does not end up in a puddle. If the model is not equipped with a frame, the body is close to the ground and water may flood the motor.
• Incorrect assembly . It is extremely dangerous for the viability of the unit to confuse the suction and supply hoses and forget to install the suction filter.

• High humidity during storage . The motor pump works with water, but it should only get into the inner chamber. All other parts may suffer from excess moisture. Therefore, when sending the unit for storage, preserve it.

• 
  Unsuitable temperature

  . The motor pump is designed for a temperature range from – 15 to + 30. Heat can lead to overheating of the engine, so it is better to install the unit in the shade. Starting the engine in cold weather is also dangerous.
• Working with inappropriate liquids . It is prohibited to pump various solutions with a motor pump, regardless of what type of impeller is installed on it. The equipment was created for pumping water, and substances with other viscosity indicators will damage the motor.
• Filling with fuel during operation . This can lead to negative results, even an explosion. First, the motor pump must be stopped, cooled, and then a new portion of gasoline must be added.
• Use 95 grade gasoline . This type of fuel has a very high combustion temperature, and also contains various additives and impurities that settle on the piston, carburetor, engine and can lead to damage to the motor pump.

Types of motor pump engines

The pump pump is driven by the following types of motors:

• Using gasoline.
• Gas.
• Diesel fuel.

Engines using the first two types of fuel differ slightly in design, and for this reason a carburetor engine can run on gas if a special gearbox is mounted on it.

Pump pumps, depending on water contamination, are divided into the following modifications:

• For purified water.
• For water containing a small amount of impurities, that is, fire pumps or high pressure pumps.
• For pumping thickened liquids and water containing significant amounts of impurities.

Motor pumps for a private home

It is much easier to water your garden yourself, pump water from a reservoir into a reservoir, or maintain a swimming pool on your own property when you have light and compact, autonomous pumping equipment on your farm. From this position, inexpensive units with two and four-stroke gasoline engines are beyond competition.

CHAMPION GP26-II

at a price of 6,100 rubles.

Portable model CHAMPION GP26-II with a centrifugal pump and 2-stroke engine, on a steel frame with anti-vibration feet. The two-stroke unit is not afraid of overturns, so the device can be transported in any position - important when transporting in small cars.

The device is affordable, repairable, and its maintenance does not require special knowledge. During intensive use, a lot of time is spent checking and adjusting the spark plug (every 30 hours), monitoring the condition and cleaning the air filter (every 50 hours)

Forte FP 20HP

at prices starting from RUB 8,337.

Medium-pressure pump Forte FP 20HP based on a 4-stroke gasoline engine with a manual starter; arranged on a tubular frame. The device uses the most compact centrifugal pump from the FP line of autonomous pumps, resulting in a sufficient power reserve and the lowest cost in the list of models with similar characteristics. There is an oil sensor that prevents the engine from starting if the lubrication level is insufficient.

The disadvantage is noisy operation.
Problems with weight can only arise in the process of overcoming long, difficult sections. Try to be as careful as possible with the nut that secures the hose fitting to the inlet pipe - its protrusions allow a lot of force to be applied, and the silumin alloy is not flexible enough to withstand excessive loads.

Pumps for purified water

For trouble-free operation, the water pumped by such pumps should not contain particles larger than 0.5 cm. Pump mechanisms are most often driven by two-stroke engines.

They are characterized by low (6-8 cubic meters per hour) productivity, quite sufficient for the needs of small farms without electricity supply in rural areas.

Motor pumps for pumping out contaminated water

Unlike the above, such pumps, which have increased productivity, pump water containing solid inclusions up to 25 mm in size without loss of performance.

Taking into account the difficult operating conditions of such pumps, the designers have provided the ability to easily remove foreign objects stuck in the pump.

For the same reason, the suction and pressure hoses for a motor pump have a diameter of 5-10 cm. Their productivity can be 2 thousand l/min, and the outlet pressure allows you to raise water by 35 m.

Device and principle of operation

Gasoline engine models designed for pumping dirty water have a fairly simple design. But their productivity is high.

Motor pumps operate on the following principle:

1. Dirty water enters the inner chamber of the pump through the pipe. It is captured by blades rotating together with the impeller.
2. The water entering the chamber is affected by centrifugal force, and it begins to be thrown towards the walls of the chamber.
3. This increases the fluid pressure. This causes water to be pushed out through the discharge pipe.
4. As a result of this process, a vacuum of air is created in the central part of the chamber, which facilitates the absorption of a new portion of dirty water.

The units consist of the following structural elements:

The design of motor pumps intended for pumping out liquid media with varying degrees of contamination can be different. Models that can easily pass through sand and even larger solids pumped out along with the liquid medium are distinguished by increased dimensions of the internal chamber and impeller. The internal chambers of units of this type are equipped with special inserts made of chromium cast iron.

Determination of motor pump parameters for use in dacha farming

To supply water to a small plot with a vegetable garden, there is absolutely no need to purchase a powerful pump.

A pump pumping 130 l/min is sufficient. at a pressure capable of providing water to consumers located above the source at a height of 6-7 meters. For larger consumers, installation of higher power units will be required.

To supply water to a residential building, a pump is required with the ability to pump 500 - 800 liters / minute and lift it by 20 - 35 m.

In order to drain a flooded area or pump out the contents of cesspools, you will need a motor pump for dirt that can pump more than 1000 l/min. with the ability to lift liquid to a height of 20-25 m.

When choosing a device, you should take into account that pumps with a carburetor engine do not require high financial investments and provide a low noise level during operation.

However, they consume a lot of fuel and have a short service life. A 4-stroke carburetor engine has significant advantages over a 2-stroke engine in that it has a much longer service life and does not require an oil-gasoline mixture.

The gas engine is 2 times more economical. A pump with such an engine can receive gas either from the main gas pipeline or from a cylinder with a liquefied propane-butane mixture.

A diesel engine has an increased service life compared to a gasoline engine - up to 5 thousand hours. A pump with such an engine is more expensive, but it is the best choice when it will operate continuously for several months.

What to look for when choosing gasoline water pumps?

Of course, gasoline pumps for pumping water from a sewer hatch, for irrigation or pumping clean water from a well are radically different. Therefore, before making such an expensive investment, you should decide where and for what it will be used.

When purchasing, you should also consider the following characteristics:

• pump performance;
• pressure;
• liquid lift height;
• outlet pipe diameter;
• size and mass parameters;
• permissible amount of impurities.

They are directly related to the price of the equipment, which is no less influenced by the manufacturer’s brand. Among the most popular and expensive in the domestic market are Honda, Briggs & Stratton, Yanmar, the quality of which is not inferior to the cheaper Caliber and Hyundai.

Prices and manufacturers

An autonomous motor pump is a highly complex unit that requires regular maintenance and costly repairs.

The electric motor, significantly different from the internal combustion engine, does not require fuel, filter cleaning, setting the ignition timing and injection timing.

In this regard, if you need to purchase a motor pump, you should choose reputable manufacturers whose products have enjoyed deserved popularity in the market for many years.

To obtain detailed information, you should familiarize yourself with photos of gasoline motor pumps of various models, manufacturers and their technical characteristics posted on the Internet.

Frequently asked questions about the operation of motor pumps

Is it possible to use a motor pump as a pump for water supply in a country house?

Yes, but not on a permanent basis. The unit is not intended for long-term or continuous operation. This is more of an emergency equipment. A full tank of fuel lasts for a maximum of two to three hours. But you can pump water into the tank and then use it as needed.

Can a woman manage and maintain a motor pump on her own?

To use a motor pump, no special training is required, but the user must have an understanding of internal combustion engines and practical skills in servicing equipment. Moving the unit may be difficult because its weight is quite large. Otherwise, ladies will not have much difficulty working with the pump.

Can a motor pump be stored in an unheated garage or shed?

Yes. The main thing is that the room is dry and ventilated. The only condition is to drain the water and gasoline from the unit.

Is it possible to pump sludge out of a pond using a motor pump?

No. The motor pump cannot be used for such purposes.

If you reduce the diameter of the pipe, will the depth of the water rise increase? If you reduce the diameter of the hose from a greater depth, will it be possible to raise water?

The diameter of the suction pipe cannot be changed, as this will lead to damage to the motor pump.

The pump stopped turning on. What is the reason?

If the pump stops turning on, the reasons may be the following: insufficient liquid level for suction or the pump drain plug is not closed. The solution is to immerse the filter in the liquid and screw the plug properly.

Is it possible to work with a motor pump in winter?

The technical data sheet of the units indicates the maximum operating conditions; we advise you to focus on them. There are motor pumps that can operate even at subzero ambient temperatures. Some indicators range from -20 to +40 °C. It is important to select the appropriate oil for such conditions. Special carburetor adjustment may be required.

FUBAG PTH 600

Questions of quality and price are the main ones when choosing any product.

To achieve high performance, Fubag, as well as DDE, prefer to equip their units with time-tested Honda engines, and they produce everything else themselves.

As a result, while maintaining high quality, motor pumps are offered at quite affordable prices: from 9 thousand for devices designed for pumping purified water, and 20 thousand rubles for mud pumps.

Budget models

Domestic manufacturers Kraton, Caliber, companies from China Elitech, Patriot, and Champion, as expected, supply their products at reasonable prices.

Motor pumps from these companies, designed to supply purified water, can be purchased for 6 thousand rubles and more.

Mud pumps from these manufacturers cost from 18 thousand rubles.

CHAMPION GP26-II

Opinions about motor pumps made in Russia and China are not unanimous.

While some are satisfied with the price/quality ratio of such units, others are not satisfied with frequent breakdowns, high repair costs and shortage of spare parts.

Main manufacturers of motor pumps

There are motor pumps on the market from Russian, Japanese and European production. Japanese equipment is characterized by the greatest reliability and smallest size.

Its estimated service life is the longest: the resource is designed for 6000 operating hours. The Japanese produce pumps that run on both diesel fuel and gasoline, but there are still more diesel models among their products.

The prices of Japanese manufacturers are slightly higher than those of competitors, including European ones.

The German brand FUBAG also produces high-quality fire extinguishing units. Its products are now manufactured in China, but this does not impair its production characteristics.

Good medium-power pumps are produced under the Russian brand “Caliber”. They are quite suitable for performing all work in the garden and in a private house, such as draining a swimming pool or basement, pumping water for watering the area.

Despite the fact that the brand is Russian, production is carried out in China.

Russian Vepr motor pumps are also good, in which Lombardini and Yanmar engines are often installed, as well as Japanese Koshin pumps.

True, the machines of this manufacturer are designed for water with a low degree of contamination.

There are also Korean manufacturers on the market. Well-known Korean auto giant Hyundai produces high-quality devices for pumping contaminated water. They are produced only in South Korea and are distinguished by high performance and reliability.

Users also recognize the so-called “good China”. Units produced by Green Field are popular because they have a very satisfactory price-quality ratio.
