Feed Pump Description
NP-ZJW series filter Press feeding pump accept unique hydraulic design and installation mode of the impeller, ensure that
its pump performance curve be more steep that normal pumps is more suitable to used in the filter press feed varies ccording to the changes of the resistance in order to realize the large capacity. low pressure feeding and low capacity, High pressure filter. the pump is widely used in the coal washery, environmental protection, alumium factory, smelting lant etc.

Selection Chart For Feeding Pump
Feed pump performance
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.
Naipu pump produce many kinds of centrifugal slurry pump for mining, sand and other solids slurry transporting.
