Typical Applications: 

Naipu NP-G Series dredge and 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.
