1. Slurry pumps PV-SP(R) series
Naipu® NP-SP(R) pumps are vertical, centrifugal slurry pumps submerged in sump to work.They are designed for delivering abrasive,large particle and high density slurries.These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties.Wet parts of type NP-SP pump are made of abrasion-resistant metal. All parts of type NP-SP(R) pump immersed in liquid are lined with rubber outer liner. They are suited to transport non-edge angle abrasive slurry.
