SC Standard Chemical Process Pump

General

Type SC standard chemical process pumps are horizontal,single-stage,single-suction,radial-split centrifugal pumps with their dimensions andperformance in conformity with ISO2858.The size 150-400 and up are proprietary.The indexes of efficiency and cavitation performance both exceed that of IH pump type.Making exchange with the single pump of these two type is allowed.

The designing of pump SC is according to ASMEB73.1,IS05199.

Application

The chemical and petrochemical industries

Refineries

The pulp and paper industries

The sugar industries

Product Features

Hydraulic design the axial force is balanced by back vanes or balancing bores at the impeller. For some sizes, the casing is designed double volute to compensate the radial forces.

Shaft seal design the shaft is sealed either by soft packing or by single or double mechanical seal with various flush plans. The secondary impeller seal will be designed when necessary.

Flange grade the suction branch and discharge branch are the same pressure grade. PN2.5Mpa is standard.They can also be designed PN1.6Mpa or 150lbs.

Structure design the pull out back structure and a spacer-type coupling is used, the volute casing and the driver need not to be removed from the pipework when maintenance.
