| Design | Continuous pumping of highly abrasive, high density slurries with minimal maintenace requirements and can be applied Multi-staged in series. |
| Outlet instalation | The positions of the pump outlet can be positioned at an interval of 45°according to different requirements. |
| Wet end parts | Both metal or rubber liners and impellers, or a combination of both, are interchangeable within the same pump to facilitate use. |
| Seals | AH cantilever, horizontal and centrifugal pump shafts can be sealed by packing seals or centrifugal type seals. |
| Maintenace | A removable cartridge type grease lubricated bearing assembly can be replaced with the pump base in-situ. |
| Special materail | Polyurethane, stainless steel, Hastelloy 276-C, ceramic and various hard wearing alloys are available on request. |

FAQFaults |
Reason | Removal |
| Pump fails to discharge any liquid. |
Incorrect direction of pump rotation and impeller worn. Suction pipe blocked |
Check direction of rotation and replace a new impeller |
| Power consumption on shaft is excessive |
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. |
Removal the rub Replace the bearing Adjust belt Modify the pump duty and speed. Adjust 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 motor. 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 replace new impeller Clean the bearing. Replace or refit the bearings. |
| Pump vibrates or is noisy. |
Bearings worn. Impeller unbalanced. Air entered into suction pipe or blocked. Flow rate is non uniform and pump not primed. |
Replaced by new bearings. Replaced by new impeller. Discharge air and remove block. Improve on the pump feeding. |
