polyurethane slurry pumps model 4/3C

Shijiazhuang Naipu pumps' strength lies in the advanced hydraulic design and the high standard of casting technology, high performance of wear life, which helps clients reduce the cost and easy operation. The wearing partsinclude impeller, volute liner, throat bush, FPL insert, shaft sleeve, seals, etc. These parts are very easily worn-out because they work under longtime impact of abrasive and corrosive slurries in the high speed. So clients will be strongly suggested to prepare enough wearing parts in  stock in case of emergent repair or maintenance, making sure the continuous steady running.

The wet parts material:
M: metal (wear-resistant ultra chrome alloy)
R: rubber (R26; R33; R55; R08; S31;S42 ...)

Slurry Pump Main parts:
• Impeller - front and rear shrouds have pump out vanes that reduce recirculation and seal contamination.
Hard metal and molded rubber impellers are complete interchangeable. Cast in impeller threads require no
inserts or nuts. High efficiency and high head designs are also available.
• Liners - Easily replaceable liners are bolted, not glued, to the casing for positive attachment and ease of
maintenance. Hard metal liners are completely interchangeable with pressure molded elastomers. Elastomer
seal rings back all liner joints.
• Throat Bush - Wear is reduced and maintenance simplified by the use of tapered mating faces to allow
positive accurate alignment during assembly and simple removal.
• Bearing Assembly - A large diameter shaft with short overhang minimizes deflection and contributes to long
bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.
