CRD, CRMD, CRDF, CRDY Multi-stage Single suction Centrifugal Pump

General Description

CRD CRND CRDF CRDY series pump is multi-stage single suction sectional centrifugal pump with excellent hydraulic model, it has advantages of high-efficiency, energy-saving, wide performance range, operating safely and steadily, low noise, long life and convenience for installing and repairing etc. It can deliver heat water, oil, corrosive or wearable medium by changing material of the pump or coupled with extra cooling system.

CRD series pump is used in mine and urban project for delivering clear water without solid particles or other liquids which are physically or chemically similar to clear water. The temperature of liquids must not exceed 80℃.

CRMD pump is used to deliver neutral water with solid particles below 1.5% (viscosity less than 0.5mm) and other sewage water. It is suitable for using in steel factory and mine etc. The temperature of liquids must not exceed 80℃.

CRDF pump is used for delivering corrosive liquids without solid particles, the temperature of liquids is -20℃~105℃.

CRDY pump is used for delivering oil and petroleum liquid without solid particles and viscosity below 120 centistokes , the temperature of liquids is -20℃~105℃.

The inlet pressure of above pumps is less than 0.6Mpa.

Performance Range

Capacity: 6.3-600m3/h

Instruction of pump type

For example CRD(CRMD, CRDF, CRDY) 85-67X3

CR: Company Code, means produced by CREDO PUMP

D: Multi-stage horizontal centrifugal pump

MD: Multi-stage wearable centrifugal pump

DF: Multi-stage anti-corrosive centrifugal pump

DY: Multi-stage oil centrifugal pump

85: Rate capacity is 85 m3/h

67: Rate head is 67m

3: 3 stage(3 impellers)


Type CRD (CRMD, CRDF, CRDY) pump consists of stator, rotator, bearing and shaft seal:

1. Stator: main parts is suction casing, stage casing, discharge casing and Diffusor, they are screw up by poles to become a working house. The suction direction of type CRD pump is horizontal, its discharge direction is upward; the discharge direction of type CRMD, CRDF, CRDY pumps are upward, the suction direction is horizontal, they can be made upward according to user requirement.

2. Rotor: it is consist of shaft, impeller, balance disk, and shaft sleeve etc. shaft supplied power to impeller. The axial force is balanced by disc. The shaft sleeve is mounted on shaft to protect shaft.

3. Bearing parts: it is consist of bearing body, bearing and bearing cover etc. The bearing of type 85-67, 155-67, 600-60 pump is sliding bearing, lubricated by dilute oil; the other pump bearing is rolling bearing, lubricated by grease.

4. Shaft seal: it is usually adopted soft packing seal, consist of sealing house on suction casing, packing , blocking water ring, the seal house have some pressure water to cool. Lubricate and seal pump. Type CRD pump pressure water come from pump itself, type CRMD, CRDF, CRDY pump pressure water is come from pump itself or outer water, type CRMD, CRDF, CRDY pump usually adopt mechanical seal .


The pump is driver directly by motor through coupling. View from motor end, the rotating direction of pump is clockwise.
