Product Description

Naipu® NP-G series of Dredge and Gravel pumps is designed specifically for continuous pumping of extremely aggressive slurries, with a wide particle size distribution. Capable of handling large particles at consistently high efficiencies results in low cost of ownership. The large volume internal profile of the casing reduces associated velocities further increasing component life.

Typical Applications---

Slag Granulation
Suction Hopper Dredging
Dredging
Barge Loading
Sand Reclamation
Sugar Beet
