Motor-pump belongs to the equipment, employed for efficient pumping of various fluids. The devices are used in agriculture for the drainage area and the organization of irrigation systems. Essential equipment will be in the home for an emergency water pumping in case of flooding of the basement. how choose motor pumps and what features to look for in the first place, предлагаем узнать из статьи. 
types of equipment
Dosing depends on the specific model of the design features of its pumping part. distinguish:
- Diaphragm (or membrane) pumps. Creation of system pressure for pumping of the medium is carried out by movement of the flexible membrane. Due to the lack of contact parts, such devices are well suited for pumping viscous and dense media. This is often specialized equipment. Used for drainage of flooded marshy places, water from muddy rivers fence, removing animal waste on farms. In everyday life diaphragm pumps are used for pumping wastewater from a sewage pit.
- centrifugal pumps. Equipped with a rotating blade rotor. When the centrifugal force formed, due to which the absorption of water into the hose. Such models are used for pumping fluids inviscid. Basically, This general-purpose machinery, which is used for emergency pumping water, with irrigation / agricultural land, firefighting, Filling the tank or vessel large amounts of liquid.
Type of Fluid
The price of centrifugal pumps depends largely on the manufacture of the pump materials. It depends on the quality of resistance to abrasion. Respectively, the type of pumped liquid, Equipment can be divided:
- For clean water. The solids in the water are not allowed.
- For slightly soiled water. The size of the solid fraction in water should not exceed 0,5 – 2,5 mm.
- Dirty Water. May be used for pumping liquids with particles prior to incorporation 3 mm.
- For heavily contaminated water. Can handle liquids with solids up to 9 – 10 mm.
Specifications of engine driven pumps
The choice of such equipment is based on such parameters:
- Performance. Inefficient models are capable of pumping up to 5 – 10 m2 of water per hour. They are used for filling containers and the organization of small plots of irrigation systems. High pumps can serve to 60 m2 / hour or more. This equipment is for emergency use in firefighting, reservoirs for draining and dewatering of large capacity tanks, pools.
- suction height. An important parameter, taken into account when taking water from the well. Suction height at different models could be up to 6 – 8 m.
What other options are different pumps, can see here. Among the wide range of pumping equipment is much easier to find the optimum solution for every application. By comparing the characteristics, you can pick up great equipment at an affordable cost.
