1. Mainly slurry pump spare parts

Naipu Slurry pump and standard spare parts with high anti-abrosive can be supply with huge amount within a short period.


Impeller, Casing, shaft, throat bush, wear plate, case, cover, stuffing box, lantern restrictor, cover plate bolt, volute, throat bush, shaft sleeve, cover plate liner, frame plate liner...

2. Sand pump spare parts feature

The impeller is the main rotating component which normally has vanes to impart the centrifugal force to the liquid.

Most slurry pump casing are "slower" than their water pump cousins, primarily to reduce wear though lower internal velocities.


Wear resistant cast alloys are used for slurry pump liners and impellers where conditions are not suited to rubber, such as with coarse or sharp edged particles, or on duties having high impeller peripheral velocities or high operating temperatures.

Front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Hard metal and molded elastomer impellers are completely interchangeable. Cast in impeller threads require no inserts or nuts. High efficiency and high head designs are also available.
