Reliable pulp transportation is the key to stable production in the concentrator. Naipu centrifugal pump has a solid structure and is suitable for the harshest operating conditions and most abrasive applications. It has high performance, low energy consumption, long service life and convenient maintenance .

 

Naipu® NP-HM series centrifugal slurry pumps and spare parts could fully interchange with world famous brand.These pumps are of heavy-duty construction, designed for continuous pumping of highly abrasive and corrosive slurries. They feature a wide choice of replaceable abrasion resistant metal casting liners and Impellers, which are all interchangeable within a common casting assembly.

Typical Applications

Dense media transfer
Dense media make-up
Bottom boiler and fly ash
Ferrosilicon make up
Thickener underflow
