Multistage centrifugal pump structure

The basic structure of the multi-stage pump is composed of the water inlet section, the outlet section, the middle section, the rear cover, the impeller, the pump body, the pump shaft, the bearing, the sealing ring, the stuffing box, etc.
1, the impeller is the core of the multistage pump, its speed is high, the impeller blade and play a major role, the impeller need through the static equilibrium experiment.Requirements on the impeller surface smooth, to reduce the friction loss of water flow.
2 is a multi-stage pump, pump shell body.Support and fixation effect, and connected to the installation of bearing bracket.
3, the role of pump shaft is connected by coupling and motor, the torque of the motor to the impeller, so it is a major part of the transmission torque.

Horizontal multistage centrifugal pump:

DF-DY-D-DG-Model-Multistage Centrifugal PumpD DF DY DG Series pumps are in multistage single casing sectional horizontal construction designed in accordance with API610, for high-head pumping various kinds of liquids without solids, applicable to a wide range of tough and heavy circumstances.
