The impeller is one of the key components of a centrifugal pump. Wear of the impeller is a frequent problem due to the frequent operation in harsh environments. Pump impeller wear can also have some serious consequences. For example:

1 The current and outlet pressure is unstable, causing the pump to swing violently;
2 The vibration of the pump increases. There are abnormal noises such as metal friction in the pump.
3. The axial movement of the pump increases. The temperature of the pump casing and bearing increases;
4 The flow at the pump outlet is reduced.
