High Capacity Submersible Water Vertical Centrifugal Pump With Rubber Liner
1. Vertical type single stage centrifugal slurry pumps
2. Application for sump pumping, Single stage pump
NP-SP(R) centrifugal slurry pumps are mainly used to pump high-hardness, strong-corrosion and high-concentration liquids that contain suspended solid particles, such as finished ores, refuse ores, ashes, cinders, cements, mud, mineral stones and etc.
Sump pump specification:
D: 40-200 mm
Q: 17-891 mm
H: 4-37 m
Slurry Pump Function:
1. Wear-resistant metal, the impeller selection of wear-resistant metal or rubber material.
2. NP-SP(R) type sump pump parts, immersed in liquid rubber lining.
3. Different length of the pump drive shaft or inhaled could be selected
4. V-belt drive, direct drive, and flexible coupling.
5. Bearing to lubricate oils.
6. use of variable speed, the best condition in the pump operation, long service life, run- effective,meet many bad transportation conditions.

Possible faults and removal:
Type AH(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 | Air leaking into suction or gland Incorrect direction of pump rota- tion | 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. | Loosen gland bolts. Removal the rubbed part. |
Bearing is over hearing | Lubricants too much or less. | Lubricating as requirements. |
Bearing has short life. | Misalignment or unparallel of drive Foreign object entered into the bearing or insufficient lubrication. | Adjusting drive and pump shaft. |
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 | Bearings worn. | Replaced by new bearings. |
