Product Description

NP® G 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.
The heavy-duty Dredge pump typically for low head high volume duties whereas the Gravel pump is best suited to the higher head cyclone feed and long distance pipeline duties.
