The "EMS" type wells unit is a pumping unit consisting of a multi-stage pumps and a drain-free electro engine, which is tightly connected to the winding stopper. The pump rotor and the electric motor rotor are rotating in the bearings. The pumps are wet with water taken away. The water in the well is put in a column of water that is lifting up and thrown into the water altogether. The main materials of the pump are gray cast iron, carbon steel, fluoroplast, plastics. EMS well pumps can never operate "dry" - even in the shortest possible time, the use of the pump without the pump will result in failure of the bearing and the motor boom. The base of the electric motor is located on the base station, and it receives its own load. When entering the pumps of the aggregate there is a protective net-filter, which protects the pumps from falling into large mechanical parts. ChEDS centrifugal pumping motor with short-circuited rotor of "belichka kletka" water and rotor synchronous rotation frequency 3000 m / min. Equipped with. Cooling of the electric motor is made with the extracted water. The Agregat 380V connects to a three-phase network, protecting the engine from stationary mode by using the 50 Hz automatic control station and the Ascend shield.
