Grave Sand Slurry Pump Application....................................................................................

Naipu® Sand gravel slurry pumps are designed to handle very large particles for gravel and dredging operations. Naipu dredge and gravel slurry pumps are designed for the continuous handling of the most difficult higher abrasive slurries, containing solids too large to be pumped by a standard slurry pump.
They are suitable for delivering slurries in Mining, explosive-sludge in metal melting, dredging in dredger and course of rivers and other fields.

1. Construction of this pump is of single casing connected by means of clamp bands and wide wet passage.

2. The wet-parts are made of Ni-hard and high chromium abrasion-resistance alloys.

3. The discharge direction of pump can be oriented in any direction of 360°.

4. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and Abrasion-resistance
