The device is made up of pump, motor and base of a few areas. Pump composition, such as pump, impeller, pump include, mechanical seals and other factors. Pump for one-stage one suction lying Centrifugal, pump physique and pump go over two elements from the back of the impeller at the split, that is, the construction of the rear door. Most pump impeller entrance and rear are presented with a seal ring, and the impeller back protect Well balanced holes are presented on the plate to balance the axial forces performing on the rotor. Pump inlet for the axial horizontal inhalation, the outlet is arranged vertically up. Pump and motor coaxial, motor shaft extension stop use
Double angular speak to ball bearing structure can partly harmony the pump residual axial drive. Pump and motor immediate link, installation with no correction, with a frequent foundation, and vibration isolation with JG-type isolator.
