1、Casing support

Foot or shaft centerline mounted for large sizes and high temperatures

2、Suction branches

Large suction branches optimize inlet flowReduce noise levels through low branch velocitiesAllow higher forces and moments

3、Impeller

Modular hydraulics for high efficiency in a wide range of operating conditionsLow net positive suction head required (NPSHR) first stage; double suction first stage canbe provided for selected sizes

4、Shaft

Stiff design resulting in higher critical speed than running speed and small shaft deflectionAreas 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、O-rings

Casing sealing by confined O-rings, therefore unaffected by rapid temperature variationsand high pressures

7、Multiple bearing types

Antifriction bearings for low cost and hydrodynamic bearings for higher energy services

8、Material Options

API 610 Material codes: S-5 S-6 S-8 C-6 A-7 A-8 D-1 D-2
