1、Barrel casing

Centerline mounting absorbs high forces and momentsPre-warming not required

2、Diffuser type

High head per stage and balanced radial loadsAllows replacement of individualstage pieces

3、Impeller

Each impeller is securely retained in both directions by a split ring with a key to transmit the torque

4、Rotor design

Dynamically balanced rotor for smooth operationShaft of areas subject to wear are protected

5、Hydraulic thrust balancing system

Axial thrust can be balanced by balance drum with thrust bearing or by balance disc withoutthrust bearing

6、Winding gasket

Casing sealing by metal winding gasket, therefore unaffected by rapid temperature variationsand high pressures

7、Multiple bearing types

Antifriction bearings for low cost and hydrodynamic bearings for higher energy servicesSelf-equalized tilting pad thrust bearing to accommodate thrust variations in translent conditions
