G Series Large Heavy Duty Sand Pumps

Naipu® NP-G
Series of Dredge and Gravel pumps is designed specifically for continuous pumping of extremely aggressive slurries, feature larger impellers and heavier casing construction, 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. Sizes range from 100mm up to 600mm.
Typical Applications
High density slurry transfer;
Thickener underflow recirculation;
