Introduction to the technical terms of slurry pumps:

High lift pump: pump with regular point head higher than 50m.

Low-lift pump: pump with regular point head less than or equal to 50m.

Minimum size of flow passage section: Minimum size of flow passage section of impeller, shell and other flow passage components.

Vulnerable Overflow Parts: Parts that are easy to fail due to slurry abrasion, such as impeller, sheath and shield of double-shell pump, pump body and pump cover of single-shell pump.

Metal skeleton of rubber-lined parts: Metal components placed in rubber to support and fix rubber.

The first critical speed: the pump speed when the first (lowest) transverse natural vibration frequency of the rotating part of the pump is different from the rotating frequency.
