PNSL vertical sludge pump is upgraded and developed by our company on the basis of like products at home. The improved PNSL pump has high efficiency, good overflowing condition, abrasion resistance and long service life, and is widely applied to cleaning up and filling sludge in lake and river.

The pump can be combined with high-pressure clean water pump to form a hydraulically excavating and filling machine set for dredging and filling operations. In addition, it can also combined in series with several vertical pumps and a marine-land purpose horizontal sludge pump to form an operation group.
