15 best motor pumps — rating 2021

The best motor pumps for heavily polluted water

Motor pumps of this type are suitable for pumping water with a large amount of dirt and aggressive liquids. They are used both in industry and for cleaning residential areas. As a rule, a dirty water pump has high power and performance, as well as a large throughput — they can pump liquids with large debris particles. The pumps are protected by coarse filters. Models are both centrifugal and diaphragm — for pumping thick and viscous liquids.

Faults and their elimination

The best motor pumps for moderately polluted water

Pumps for medium and slightly polluted water are used in country houses, farms and summer cottages, to extinguish fires. They can suck up dirt particles, like motor pumps for heavily polluted water, but the particle diameter will be much smaller. Most often it does not exceed 20-15 mm. For protection, filters in a medium-sized grid are used. For many pumps of this type, interaction with aggressive liquids is undesirable. Models weigh a little, are quite mobile and compact. They have high performance and power, which allows them to cope with large volumes of work.

Main types

All motor pumps are divided according to the type of tasks to be solved into three main types:

• Firefighters. Pumps are distinguished by high pressure, in addition to extinguishing fire, they can be used in construction and domestic needs, when supplying water to high floors or long distances, usually pumps of this type are less mobile than their counterparts.
• Mud. Designed for draining swampy areas, cesspool activities and other work with polluted water. Therefore, they are made of especially durable materials and equipped with powerful engines.
• Pumps for clean water. Equipped with engines of small capacity, the design necessarily contains a fine-mesh filter to prevent solid particles from entering the unit.

The best motor pumps for clean water

Motor pumps for clean water are much more compact and lighter than models for medium and very dirty water and have lower performance. The engine can be either four-stroke or two-stroke. They are mainly used for watering summer cottages and autonomous water supply. They are also used to clean swimming pools. The models have a very low throughput of debris particles. At most, it can be simple debris in the form of silt and sand with a particle diameter of up to 5 mm. For protection, fine mesh filters are used. Such motor pumps are unpretentious, inexpensive and can run on cheap gasoline.

Operating rules

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

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

• Pour some water into the chamber before starting work. This will prevent dry running. In models with protection, a dry start will not occur at all.

First start

After the motor pump is correctly installed, you can start the liquid pumping process:

1. Install the suction pipe through the seal to the suction flange and tighten the nut.
2. Push the suction hose in as far as it will go.
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 pumping chamber with water through the opening provided for this purpose.
6. Close the air damper.
7. Move the throttle lever to the middle position.
8. Press the fuel suction lever into the carburetor several times.
9. Repeatedly sharply, but without jerks, pull the start handle (magneto) towards you.
10. Once the motor has started, fully open the choke in the direction indicated on the installation.
11. Move the throttle lever to idle and warm up the engine for 15-20 seconds.
12. Subsequently, use the gas control lever to transfer the operation of the motor to the required mode.

The motor pump is turned off in the reverse order:

1. Move the throttle lever to idle and the choke to the middle position.
2. After 2-3 minutes of operation, close the fuel cock.
3. When the carburetor runs out of fuel and the engine stalls, turn the main switch to the off position.

How to properly serve

Like any technical equipment, a motor pump needs 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:

• Oil change. The engine oil should be checked regularly and topped 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. Most pump manufacturers recommend replacing the filter every 50 hours.

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

What can cause breakage

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

So that the unit does not fail, you need to know what it is afraid of:

• Hits and falls. Excessive mechanical impact is dangerous for any technique. 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, or the hose may come off or the inlets may be deformed. During falls, oil or fuel may leak out, which subsequently disrupts the operation of the engine.
• The wind that raises the dust. The air filter will definitely not like this.

• Rain. Small drops will not damage the motor pump, but it is better not to expose it to strong shower jets. It is also important to ensure that in humid 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 can flood the motor.
• Incorrect assembly. It is extremely dangerous for the viability of the unit to confuse the suction and delivery hoses and forget to install the suction filter.

• High humidity during storage. The motor pump works with water, but it should only enter the inner chamber. All other parts from excessive moisture may suffer. Therefore, when sending the unit for storage, carry out its conservation.

• 
  Wrong 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 unintended liquids. It is forbidden to pump various solutions with a motor pump, regardless of which impeller is installed on it. The technique was created for pumping water, and substances with other viscosity indicators will disable the motor.
• Filling fuel during operation. This can lead to negative results, up to an explosion. First, the motor pump must be stopped, cooled, and then a new portion of gasoline must be added.
• Use of 95 brand of 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 breakdowns of the motor pump.
