Product Description

NP-A H Slurry pump is horizontal centrifugal heavy duty slurry pump and it is designed for the continuous pumping of high abrasive, high density slurries with minimal maintenance requirements. It will maintain high efficiency over the wear life of its components. The rubber and metal lined pumps feature casings which are radially split into two halves. Minimum casing bolts reduce maintenance and minimise downtime. The pumps of HS can be installed as multi-stage series.

Features:
1.Replaceable wear-resistant metal or rubber liners and impellers, long service life time. 
2. Easy to adjust the space between impeller and front liner and can be removed completely when maintaining. 
3.Bearing assembly use grease lubrication. 
4. Seal types: packing seal, expeller seal and mechanical seal. 
5. Discharge direction can be installed at intervals of 45 degrees as request and oriented to any eight positions to suit applications. 
6. Drive types: V belt drive, gear reducer drive, fluid coupling drive, and frequency conversion drive devices. 
7. Wide application, good NPSH and high efficiency. The series pump can be installed in multistage to meet the delivery for long distance.

Possible faults and Solution:

Type A H(R) series pump has a compact construction. If it is correctly installed and operated, the pump will have a long life.

 

Faults	Reason	Removal
Pump fails to discharge any liquid.	Air leaking into suction or gland Incorrect direction of pump rota- tion and impeller worn. Suction pipe blocked	Sealed leakage. Check direction of rotation and replacing a new impeller. Removal lockage.
Shaft Power consumption is excessive	Gland excessively tightened against packing rings. Rotating component is rubbing on a stationary part. Bearing worn. Drive belt tension too tight Flow rate too large Pump speed and 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 and pump shaft.
Bearing is over hearing	Lubricants too much or less. Containing impurities in the lubricant Bearing worn.	Lubricating as requirements. Replace clean lubricant. Replace new bearing.
Bearing 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 is none-uniform and pump not primed.	Replaced by new bearings. Replaced by new impeller. Discharge air and remove block. Improve on the pump feeding.
