Application and Feature
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 slurypump.
They are suitable for delivering slurries in Mining, explosive sludge in metal melting, dredging in
Dredger and course of rivers and other fields.
Construction of this pump is of single casing connected by means of clamp bands and wide
Wet passe.
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
