Type XR 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.
