The impeller and expeller of slurry pump

1.Impeller is the key components of slurry pump.

(1)According to its mechanical structure impeller can be divided into closed, semi-closed and open three. Closed impellers are suitable for conveying clean liquids; semi-closed and open impellers are suitable for conveying suspensions containing solid particles, which are inefficient.
(2)According to different suction method, the impeller can be divided into single suction type and double suction type. The single suction impeller has a simple structure and the liquid can only be sucked from one side. Double-suction impeller can be symmetrically drawn from both sides of the impeller of the liquid, it not only has a large liquid absorption capacity, and basically eliminate the axial thrust.
(3) According to the geometry of the blade on the impeller blade can be divided into back bending, radial and forward bending of the three, because the curved curved blade is conducive to the kinetic energy of liquid into static pressure, it is widely used.

2.Expeller is also one of the important parts of slurry pump.

It combined with the decompression cap slurry pump power seal, is one of three types of shaft seal.

Slurry pump expeller standard material is generally gray iron or ductile iron, but also in accordance with customer requirements to flow parts material A05 made in recent years, most customers to buy, more inclined to AO5 high chromium wear-resistant alloy material.
