General

Type CRXR hot water circulating pump, according to API610 and VDAM24297(light/medium duty), it is advanced products developed from type R hot water circulating pumps with high serialization, standardization and generalization. The pumps have advanced performance, stable operation, safe and reliable. It is  used in metallurgy, power stations, chemical industry as well as heating system or closed circle system for handling hot water circulating and exchange-heating. The highest temperature of the liquid can not be over 250℃. Working pressure is not allowed more than 5.O MPa.

Construction

Type CRXR hot water circulating pump is the kind of single-stage, single-suction overhanging centrifugal pump with horizontal axial suction and radial upward discharge. 

The pump casing is radial split which installed horizontally with supported on the center line. Especially suitable for high temperature and high pressure and transport inflammable and explosive liquids.

The shaft seal is mechanical seal or packing seal. The pump used rolling bearings which get lubricated with dilute oil.

The direction of rotation

The rotation of the pump rotor is clockwise looking from the motor to the pump.
