How Is Slurry Pump Impeller Designed?

 How Is Slurry Pump Impeller Designed? - Introduction


Slurry pump parts - slurry pump impeller takes an important role of slurry pump in hydraulic performance of fluid flow and working head, the efficiency of slurry pump impeller achieve can also help the slurry pump engine power, in order to achieve long wearing life in slurry pump operation, a proper pump impeller must be designed.

Without understanding the function of slurry pump impeller, we will never understand how a slurry pump is designed.


In general saying, the slurry pump is equal to the slurry pump energy converter.


The function of slurry pump impeller is by using a rotating impeller to impact energy in centrifugal performance of slurry mass and accelerate the slurry transferring from one place to another.

How Is Slurry Pump Impeller Designed? - Vane Design


China slurry pump Do Pump shows below as the kinetic and hydraulic force which is generated by the slurry pump vanes, which are the heart of the impeller, whereas, the rest of the impeller design is to carry, protect and balance the impeller vanes during the slurry pump operation. 


How Is Slurry Pump Impeller Designed

Slurry pump impeller is designed with external and internal vanes. The external vanes are also known as pump out or expeller vanes are in shallow and located on the outside of the impeller shrouds, the external vanes are designed for pump sealing system and slurry pump efficiency. On the other hand, internal slurry pump vanes are designed as main vanes which actually the part for slurry pumping, the internal slurry pump vanes are two types, one type is Francis Vanes and the other is Plain Vane

How Is Slurry Pump Impeller Designed? - Number of impeller vanes?


”More vanes gives higher efficiency. This means that the maximum number of vanes is always used whenever practical”. (The exception is torque flow.) Limitations are created by the vane thickness required for good wear life and the need to pass a required particle size.

Maximum number of vanes in practice is five which are used on metal impellers with a diameter exceeding 300 mm and rubber exceeding

500 mm.

Below these diameters, the vane area relative to the impeller area becomes critical (too large vane area, giving too much friction) and

efficiency starts to drop and blocking can occur.
