International Standard Chemical centrifugal pump
Inlet diameter is50mm
Outlet diameter is32mm
Nominal impeller diameter is 160mm
Impeller first cut
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 ording 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.
