Instruction of pump type
For example 300CRS19A
300: Inlet diameter is 300mm
CR: Company Code,means producedby CREDO PUMP
S: Single-stage double-suction centrifugal pump with horizontal split casing.
19: Max Head
A: A, B, C separately represents that outer diameter of impeller is changed the first, the second and the third time.
Structure
Type CRS pumps are horizontally installed, the casing and the cover of 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 elements will be removed without disturbing the inlet piping and the outlet piping, only dismantling the pump cover while maintenance. The shaft seal uses packing seal or mechanical seal.
The direction of rotation
Looking from the motor to the pump, i.e. the pump inlet is on the left and the outlet is on the right. The rotation for type CRS pump is clockwise. The driver (motor) can be connected with the other end of pump shaft according to customers' requirements, meantime, the rotation, the direction of inlet and outlet are opposite to the above-mentioned rotating .
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.
