General Description

Type CRS pumps are single-stage double-suction centrifugal pumps with horizontal split casing. They are widely used for water supply & drainage in fields of factories, cities, mines, power stations and faemlands sa well as water conservancy. The are provided for delivering clear water without solid particles or other liquid which is physically and chemically similar to clear water. The temperature of the liquid is 0℃～80℃. Permissible maximum inlet pressure is 0.6MPa.

Performance range

Capacity: 72~20000m³/h

Head:  11 ~ 186m

Instruction of pump type

For example    300CRS19A

300: Inlet diameter is 300mm

CR: Company Code，means produced  by 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.
