Product Description

Vertical centrifugal pumps are divided according to the installation method: the inlet part is underwater, the motor is above the water; the inlet part and the motor are both underwater
Vertical centrifugal pumps are divided according to the conveying medium: one is to convey solid particles, the other is to convey foam


Naipu® NP-SP 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.
