Petrol motor pump — how to buy the best model and an overview of the options for using the device (60 photos)
The practice has already remained in the distant past, when the only way to water the garden and lawn was a watering can, and water had to be carried in buckets. Now there are many devices in the arsenal of a summer resident and gardener that have made his life easier by reducing the level of unnecessary physical activity. The usual gasoline motor pump brings great benefits. It helps to quickly solve the issue of water supply to the site and prompt removal of dirty sludge after heavy precipitation or flood.
This device is a self-priming water pump. It is powered by a gasoline-fueled engine. It is intended for effective solution of tasks in the field of water supply, irrigation or pumping of liquid. Some models can be used when extinguishing a fire.
Gasoline equipment is not too heavy, it can be easily carried around the territory of the suburban area. Such mobility and maneuverability allow not only to deliver the device to its destination by car, but also to quickly solve several tasks on extensive suburban allotments.
The following main components are distinguished in the design of the equipment:
- internal combustion engine;
- air type filter;
- fuel tank;
- pumping system.
The liquid first enters the intake hose for the motor pump. In the process of moving along it, the effect of centrifugal force acts on the water, and therefore it is directed inside the equipment itself. After that, the composition is pushed out of the nozzle.
Device Selection Features
If you have set yourself the question of how to choose a motor pump with the best action parameters, it is necessary to consider its most important parameters.
First, you should calculate the height of the liquid supply. To do this, you need to find out what is the distance between the fence site and the location of the device.
Remember, the rise of the fraction by 1 m up corresponds to its horizontal movement by 10 m. The suction depth can vary between 7-9 m.
Secondly, it is advisable to evaluate the availability and quality of filters on the suction hose. The durability of work without breakdowns and the frequency of routine maintenance will depend on this.
Thirdly, the design of the pumping system itself is also important. According to this parameter, devices can be divided into two large groups:
In the first version, a special wheel is provided, which is necessary for pumping. The membrane type is focused on extracting thicker fractions that contain a small amount of moisture.
It is also important that this equipment has a completely different purpose:
- transfer of water without contamination;
- pumping or feeding clean liquid or low-polluted;
- 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 liquid pumped by the motor pump per unit of time. The purpose is taken into account here:
- for convenient watering of the garden 130-150 l/min.;
- for a full water supply of the house, a large capacity will be needed – up to 1.7 l/min.;
- ensuring the filling of the pool — 1 thousand liters/min.;
- drainage of a heavily flooded area – 1.2 thousand liters/min.
Remember, the required efficiency is determined not only by the purpose of application, but also by the parameters of pipes, lifting height, 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, give high performance with affordability for buyers. But at the same time, certain maintenance requirements are imposed, for example, constant refueling is necessary.
All available gasoline-powered 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 efficiency ratio of productivity and cost.
Two-stroke engine model
For use in the country, a compact push-pull device is considered the best option. A small productive version, lightness and mobility allow you to carry it around the site.
Moreover, one person can do this without outside help. It will fit in the trunk during transportation. You can really evaluate these advantages by the 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 at a capacity of 7.2 thousand liters/h. The DDE PN25-II model is equipped with a 53 cm3 "engine" and has a power of 2 horsepower. With a product weight of 7-7.3 kg, the considered devices are very effective in operation.
Four-stroke engine type
This design is larger, has excellent performance. Due to the high power, it is advisable to use the "engine" for large volumes of work with a high degree of load.
In suburban areas, such models are often used when supplying liquids over long distances. The advantage is the technical durability and the absence of the need to prepare mixtures of gasoline with oil.
Popular brands are Koshin, Robin-Subaru, Hammer. For example, the Hammer MTP 4000 with an "engine" in 4 cycles at 5.5 l.s. provides a rise of 36 thousand liters of water by 8 m per hour of operation. 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 liters / h.
Main types of equipment
It is necessary to choose a pumping system depending on the purpose and purpose of use. So you can optimally solve the problem at the cottage or in a country house.
System for pumping clean water
For these purposes, a light and compact model with a two-stroke engine is suitable. It is used for filling the pool, watering the garden or water supply at home. The productivity is not too large, as a rule, no more than 6-8 m3 per hour.
The water pump is equipped with special filters that prevent the penetration of particles of more than 5 mm. An important advantage is maximum mobility due to low weight and compactness. Such maneuverable pumping devices can easily fit in an ordinary backpack.
These units are successfully used to quickly extinguish fires and pump water over long distances. The four-stroke engine gives a high performance of 400-600 l/min. with a liquid rise of 60 m .
This option is especially advantageous if there is no centralized water supply on your site, and the natural reservoir is located at a great distance. By weight, high-pressure devices are not much heavier than conventional pumping structures.
Aggregates for contaminated liquid
A dirt pump is a powerful and high–performance device. You can pump up to 2 thousand liters of liquid per minute, lifting it to a height of up to 35 m. This design is equipped with inlet/outlet type pipes having a diameter of 50-100 mm. The equipment is effective for pumping dirty mixture from flooded areas, cleaning septic tanks, wells.
It is possible to pass particles with a size of 25-30 mm through the filters. The composition of such water may contain elements of lime, sand, clay, crushed stone, silt of high concentration.
To clean the filters, access inside is made 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 singled out.
When choosing a gasoline-powered motor pump, study the technical characteristics in detail. But it is equally important to correctly calculate the conditions of its actual use. It is advisable to estimate the length and height of the feed. After that, it is necessary to compare these calculated indicators with the dependence of performance on their changes. This will be the real basis for the correct selection of the model.
