设计特点Design

◆Hydraulic design: Double or single suction.single or double stage, volute discharge casing,and spiral suction casing.

◆Casing: Top discharge, top suction, nozzles loadcompliance with APl 610, radially split,centerline support. Casing cover distributed symmetrically.

◆Flange: The suction and discharge nozzles with same pressure grade, are vertically arranged.Allowable nozzle loadings complie with APl610.

◆Shaft seal: Various cartridge mechanical seals available, single, double or tandem mechanical seal with various APl682 auxiliary system.Camber dimension compliance with APl682.The shaft seal box could be cooled by water.

◆Bearing Housing: Large diameter bearing housing with cooling plans made by CS, oil lubrication be available.

◆Shafting: Heavy duty shaft design and bearings support have heavy duty carrying capability.Sleeve bearing or antifriction bearing could be selected.

◆The direction of rotation is clockwise seen from drive end.
