Naipu® G gravel sand 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.
Designed Feature
- Construction of this pump is of single casing connected by means of clamp bands and wide wet passage.
- The wet-parts are made of Ni-hard and high chromium abrasion-resistance alloys.
- The discharge direction of pump can be oriented in any direction of 360°.
- This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and Abrasion-resistance.
Typical Applications---
- Slag Granulation
- Suction Hopper Dredging
- Dredging
- Barge Loading
- Sand Reclamation
- Sugar Beet
