Structure

 The pump is single-stage single-suction overhanging centrifugal pump. The pump is back pull-out type. It is unnecessary to disturb the intel piping, outlet piping and pump casing, the impeller can be dismantled for maintenance.

The shaft seal adopts packing seal or mechanical seal according to customers ‘requirements. The pump uses rolling bearings which get lubricated with dilute oil.

Rotation direction

 The rotating of the pump rotor is clockwise looking from the motor to the pump.

Material of main parts

The medium-contacting parts are made of alloy stainless steel, material No.ZG1Cr18Ni9 and ZGCr18Ni12Mo2Ti,etc.

Parts range

Pump, Motor, common bedplate, coupling, check value and sluice valve.
