Structure
*CRGS pumps are horizontally installed, the casing and the cover of the pump are divided along the axis.
*The pump cover is above the shaft and the casing is under the shaft.
*The inlet and the outlet are under the shaft.
*The centerline of inlet and outlet is perpendicular to the axis.
*The rotor can be removed without disturbing the inlet pipe and the outlet pipe, only dismantling the pump cover while maintenance.
*The shaft seal uses packing seals or mechanical seals.
The direction of rotation
The rotation for CRGS series pump is clockwise looking from the motor to the pump, for example, the pump inlet is on the right, and the outlet is on the left. The motor can be connected with the other end of pump shaft according to customer's requirements, meantime, the rotation, the direction of inlet and outlet are opposite to the above mentioned.
Material of main parts
The medium-contacting parts are made of cast iron.
The material of impeller: cast steel /brass /according to customer's requirements.
Parts range
Pump, Motor, Coupling joint, Foundation plate and Mounting resistant cushion will be supplied when inlet diameter of pump is less than 200mm, more than 200mm inlet diameter will only supply pump, motor, coupling joint.
