Heavy Duty Centrifugal Dredging Suction Sand Pressure Gravel Pump
The ZG(GH) dredge pump or called as sand gravel pump is single-stage,single-suction,single-casing horizontal slurry pump,and the zGH pumps are high head ones.The pumps are designed for continuously transferring strong corrosive big-solid-contained slurry which the common slurry pump cannot transfer.They are widely used in mining ,explosive-sludge in metal melting,dredging in dredger etc.

Pump Prossible faults and removal:
Type ZG 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. |
Incorrect direction of pump rota- tion and impeller worn. Suction pipe blocked |
Check direction of rotation and replace a new impeller |
|
Power consumption on sh- aft 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 ddrive 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 none—uniform and pump not primed. |
Replaced by new bearings. Replaced by new impeller. Discharge air and remove block. Improve on the pump feeding. |
