Horizontal Multistage Centrifugal Pump
The Horizontal Multistage Centrifugal Pump is the largest multistage pump in the D range with the highest performance capabilities in terms of both flow and pressure. Designed with multiple impeller for the high pressure transfer of water and other clean, low viscosity fluids, this model of pump is ideal for water pressure boosting, circulation and large volume transferring across long distances.
Its long coupled design means that this multistage pump requires simpler and easier maintenance as you can get to the pump head without having to remove the motor first. It is also more durable for heavy duty, continuous operation as it has two separate bearing supports with separate oil chamber s to share the strain. This horizontal centrifugal pump is able to absorb any vibrations caused by operation thanks to its flexible rather than rigid coupling.
A further benefit of the Horizontal Multistage Centrifugal Pump is that its suction and discharge connections can be rotated in 90° stages at manufacturing stage to match existing pipework for easy retrofitting. It also benefits from wear rings, which limit the wear caused to the casing and impellers.

Model meaning
D -- indicates multi-stage clean water centrifugal pump
DF--indicates corrosion-resistant multi-stage centrifugal pump for mining
DY--indicates multi-stage centrifugal oil pump
MD--indicates mining wear-resistant multi-stage centrifugal pump
D
Used to transport clean water without solid particles and at a temperature below 80°C or liquids with physical and chemical properties similar to clean water. Suitable for mines, factories, and urban water supply and drainage projects.
DF
Used to transport corrosive liquids without solid particles and at a temperature of -20°C to 105°C. The allowable inlet pressure of the pump is less than 0.6MPa. Users can reasonably select the material, sealing form,and structure of the pump and determine the capacity of the motor according to the name, concentration, specific gravity, operating temperature, and inlet pressure of the transported medium.
DY
Used for conveying oils and petroleum products without solid particles, with a temperature of -20℃~105℃ and a viscosity of less than 120 centimeters.
MD
Used to transport neutral mine water and other similar sewage with particle content ≤1.5%, particle size ≤0.5mm, and temperature between -20~80℃.
Products Structure
Stator portion
Consists of suck-in section,middle-section,spitting section.guidevane,packing etc.,which are linked together with a take-up bolt,with both suck-in and spitting mouths vertically upward.
Rotor portion
Consists of ashaft, impeller, balancing disk, muff etc. parts.
Bearing portion
The whole rotor is supported by the roller bearings or sliding bearings on both ends of the shaft and the bearings are lubricated with grease or 20 engin oil.
