multistage centrifugal booster pump  

1,What are the details about Credo D/MD/DF/DY Series pump ?

1) The serial pump is multi-stage sectional centrifugal pump with the excellent hydraulic model, it has advantages of high-efficiency, energy-saving, wide performance range, oprating safely and steadily, low noise, long life and convenience for installing and repairing etc. It can delivery heat water, oil, corrosive or wearable medium by changing material of pump.

2) Type D 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 are not be over 80 °C.

3) Type MD pump is used to deliver nertral water with solid particles below 1.5% (viscosity less than 0.5mm) and other sewage. It is suitable for using in steel factory and mine etc. The temperature of liquids can not exceed 80°C.

4) Type DF pump is used for delivering corrosive liquids without solid particles, the temperature of liquids is -20 °C ~105 °C. 

5) Type DY pump is used for delivering oil and pertroleum products without solid particles and viscosity below 120 centistokes, the temperature of liquids is -20 °C ~150 °C. The inlet pressure of all above pumps is less than 0.6Mpa.

2,What are the struction of the Credo D/MD/DF/DY Series pump ?

Type D/ MD/ DF/ DY multistage horizontal centrifugal 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 D pump is horizontal, its discharge direction is upword; the discharge direction of MD/DF/DY pumps are upward, the suction direction is horizontal, they can be made upword according to user requirement.

2) Rotor: it is consist of shaft, impeller, balance disc, and shafe 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) 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 D pump pressure water come from pump itself; type MD/DF/DY pump pressure water is come from pump itself or outer water, type MD/DF/DY pump usually adopt mechanical seal. 

4) Drive: The pump is driver directly by motor through coupling.
