Gasoline motor pump - how to buy the best model and review of device usage options (60 photos)

Already left in the distant past, the practice when the only way to water the garden and lawn was a watering can, and the water had to be carried in buckets. Now in the arsenal of the summer resident and the gardener there are many devices that made his life easier by reducing the level of unnecessary physical activity. The usual gasoline motor pump is of great benefit. It helps to quickly resolve the issue of water supply to the site and the rapid removal of dirty slurry after heavy rainfall or high water.

Summary of the article:

Options and principle of operation

This device is a self-priming type water pump. It is powered by a gasoline engine. Designed to effectively solve problems in the field of water supply, irrigation or pumping liquid. Some models can be used for extinguishing fires.

Gasoline equipment is not too heavy; it can be easily transported over the territory of a summer cottage. Such mobility and maneuverability make it possible not only to deliver the device to the destination by car, but also to quickly solve several problems on extensive summer plots.

The following main components are distinguished in the equipment design:

internal combustion engine;
air filter;
fuel tank;
pumping system.

The fluid first enters the intake hose for the motor pump. In the process of moving through it, the effect of centrifugal force acts on water, in connection with which it is directed inside the equipment itself. After that, the composition is pushed out of the pipe.

Features of device selection

If you have set yourself the question of how to choose a motor pump with the best action parameters, you need to consider its most important parameters.

First, you should calculate the height of the fluid. To do this, you need to find out what is the distance between the fence and the location of the device.

Remember, lifting a fraction 1 m upwards corresponds to its horizontal movement 10 m. The depth of absorption can vary between 7-9 m.

Secondly, it is advisable to assess the presence and quality of filters on the suction hose. The longevity of work without breakdowns and the frequency of routine maintenance will depend on this.

Thirdly, the design of the pumping system itself is important. According to this parameter, devices can be divided into two large groups:

centrifugal;
diaphragm.

In the first embodiment, a special wheel is provided, which is necessary for pumping. The membrane type is focused on the extraction of denser fractions that contain a small amount of moisture.

It is also important that this equipment has a completely different purpose:

water transfer without pollution;
pumping or supplying clean liquid or slightly contaminated;
redistribution of dirty and viscous mixture.

Choosing the most suitable model, you need to evaluate the most important parameter - the performance of the motor pump. It is estimated in the volume of fluid pumped by the motor pump per unit time. The goal is taken into account here:

for convenient watering the garden 130-150 l / min .;
for full water supply the house will need more power - up to 1.7 l / min .;
pool filling - 1 thousand l / min .;
drainage of a heavily flooded area - 1.2 thousand l / min.

Remember, the required efficiency is determined not only by the purpose of the application, but also by the parameters of the pipes, the height of the lift, the number of bends and connecting blocks.

Features of a gasoline engine

The gasoline engine gives the equipment high power, mobility and maneuverability. Such systems are easy to operate, provide high performance at affordable prices for customers. But at the same time, certain service requirements are presented, for example, constant refueling is necessary.

All available petrol devices can be divided into two groups:

Lightweight low power units. They are equipped with 2-5 hp two-stroke engines. with a volume of 25-50 cm3.
Four-stroke “engines” having a working volume of 100-600 cm3. They have the best performance-to-cost ratio.

Two-stroke engine model

For use in the country, the best option is a compact push-pull device. A small productive version, lightness and mobility allow you to carry it around the site.

And one person can do this without outside help. It will fit in the trunk during transportation. You can really appreciate these benefits from a photo of a gasoline motor pump.

An example of such equipment is the Champion GP26-II brand with an engine capacity of 33 cm3. Such parameters allow pumping from a depth of up to 8 m with a capacity of 7.2 thousand l / h. The DDE PN25-II model is equipped with an “engine” of 53 cm3 and has a power of 2 horsepower. With a mass of products of 7-7.3 kg, the devices considered are very effective in operation.

Four stroke engine type

This design is larger, has excellent performance. Due to the high power, the “engine” is advisable to use for large volumes of work with a high degree of load.

In summer cottages, such models are often used when supplying fluid over long distances. The advantage is the technical durability and the absence of the need to prepare a mixture of gasoline with oil.

Popular brands are Koshin, Robin-Subaru, Hammer. For example, Hammer MTP 4000 with an “engine” of 4 clock cycles at 5.5 losh.s. provides a rise of 36 thousand liters of water at 8 m per hour. The unit weighs 25 kg, which is not so much compared to analogues. Robin-Subaru PTG208 H has a capacity of 3.5 "horses" with a capacity of 24 thousand l / h.

The main types of equipment

The pump system must be selected depending on the purpose and purpose of use. So you can optimally solve the problem at the cottage or in a country house.

Pure water pumping system

For these purposes, a light and compact model with a two-stroke engine type is suitable. It is used to fill the pool, water the garden or supply water to the house. Productivity is not too big, as a rule, no more than 6-8 m3 per hour.

The motor pump for water is equipped with special filters that prevent the penetration of particles more than 5 mm. An important advantage is maximum mobility due to low weight and compactness. Such maneuverable pumping devices can easily fit in a conventional backpack.

High pressure samples

These units are successfully used to quickly extinguish fires and pump water over long distances. The four-stroke engine gives high productivity of 400-600 l / min. with a rise in liquid of 60 m.

This option is especially beneficial if your site does not have centralized water supply, and the natural body of water is at a great distance. By weight, high-pressure devices are not much heavier than conventional pump structures.

Contaminated fluid units

Mud pump is a powerful and high-performance machine. You can pump up to 2 thousand liters of liquid per minute, lifting it to a height of 35 m. This design is equipped with inlet / outlet type nozzles having a diameter of 50-100 mm. The equipment is effective for pumping dirty mixture from flooded areas, cleaning septic tanks, wells.

There is the possibility of passing particles of 25-30 mm in size through filters. The composition of such water may contain elements of lime, sand, clay, gravel, silt of high concentration.

To clean the filters, access inside is as easy as possible. The motor pump housing is convenient for maintenance and repair. Among the popular brands, ROBIN-SUBARU PTG310ST and SKAT MPB-1300 should be highlighted.

When choosing a gasoline pump, study the technical specifications in detail. But it is equally important to correctly calculate the conditions for its actual use. It is advisable to evaluate the length and height of the feed. After this, it is necessary to compare these calculated indicators with the dependence of productivity on their changes. This will become the real basis for the correct selection of the model.
