Audited Supplier NP Horizontal heavy duty slurry pump HM HR Mine MR MM slurry pump HeB
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
Dewatering

Faults |
Reasons |
Removal |
|
Pump fails to discharge any liquid.
|
Air leaking into suction or gland. Incorrect direction of pump rotation &impeller worn.. Suction pipe blocked. |
Sealed leakage. Check direction of rotation and replacing impeller. Removal blockage. |
|
Shaft power consumption is excessive. |
Gland excessively tightened against packing rings. Rotating component rubbing on a stationary part. Bearings worn. Drive belt tension too tight. Flow rate too large. Pump speed & ratio too high. Misalignment or unparallel of drive shaft and pump shaft. |
Loosen gland bolts Removal the rubbed part. Replace the bearing Adjusting belt. Modifying the pump duty and speed. Adjusting drive&pump shaft. |
|
Bearing is over heating |
Lubrications too much or less Containing impurities in the lubricant. Bearing worn. |
Lubricating as requirements. Replace new lubricant. Replace new bearing. |
|
Beraing has short life |
Misalignment or unparallel of drive and pump shaft. Shaft bent. Impeller unbalanced due to wear. Foreign object entered into the Bearing or insufficient lubrication. Incorrect procedure followed in fitting bearings. |
Adjusting drive and pump shaft. Replacing shaft. Remove rubbing and Replacing new impeller. Clean the bearing Replacing or refitting the bearings. |
|
Excessive leakage from stuffing box |
Packing rings excessive worn. Shaft sleeve worn Dirty sealing water. |
Replace new packing rings. Replace shaft sleeve Change clean sealing water. |
|
Pump vibrates or is noisy |
Bearings worn. Impeller unbalanced. Air entered into suction pipe or blocked. Flow rate non-uniform and pump not primed. |
Replaced by new bearings. Replaced by new impeller. Discharge air and remove block.. Improve on the pump feeding. |
