Medium duty slurry pumps
Cantilevered slurry pumps /horizontal centrifugal slurry pumps/slurry pumps handling highly abrasive slurries/coal mine slurry pumps/wear-resistant metal liner slurry pumps /mechanical seal slurry pumps/expeller seal slurry pumps
Naipu® NP-M 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.
Structure:
The frame plates of this kind of Slurry Pump have replaceable wear-resistant metal liners. The impellers are made of wear-resistant metal. The frame plate liner and impeller for M slurry pump are adoptable of hard metal only.
Bearing Assembly of this kind of slurry pump use cylindrical structure, adjusting the space between impeller and front liner easily, being removed completely when being repaired. Bearing assembly use grease lubrication.
The shaft seal of this kind of slurry pump could use the packing seal, expeller seal and mechanical seal. The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.
Here are the drive types, such as V belt drive, gear reducer drive, fluid coupling drive, and frequency conversion drive devices. The pump of this type may be installed in multistage series to meet the delivery for long distance.
Typical Applications---
Dense media transfer
Dense media make-up
Bottom boiler and fly ash
Ferrosilicon make up
Thickener underflow
Dewatering
