A few things you might not know about slurry pump


During the sludge pump running, various problems may occur, how to solve them quickly? Here, we list some common questions for your reference.


As below:


  1. 1.     Abrasive Slurry Pump fails to discharge any liquid

Possible reasons:  Air leaking into suction or gland

                 Incorrect direction of pump rotation & impeller worn

                 Suction pipe blocked

   Solutions: Sealed leakage

                 Check direction of rotation and replacing impeller

                 Removal blockage

  1. 2.     Shaft power consumption is excessive

Possible reasons: Gland excessively tightened against packing ring

                Rotation component rubbing on a stationary part

                Bearing worn

                Drive belt tension too tight

                Flow rate too large

         Misalignment or unparallel of drive shaft /pump shaf

Solutions:  Loose gland bolts

                Removal the rubber part

                Replacing bearing

                Adjusting belt

                Modifying the pump duty and speed

                Adjusting drive & pump shaft


  1. 3.     Bearing is over heating

Possible reasons:  Lubrications too much or less

               Containing impurities in the lubricant

               Bearing worn

  Solutions: Lubricating as requirements

               Replace new lubricant

               Replace new bearing


  1. 4.     Bearing has a short life

Possible reasons:  Misalignment or unparallel of drive shaft /pump shaft

                Shaft bent

                Slurry Pump Impeller unbalanced due to wear

                Foreign object entered bearing /insufficient lubrications

                Incorrect procedure flowed in fitting bearings

  Solutions:  Adjusting drive and pump shaft

                Replacing shaft

                Removing rubbing and replacing new impeller

                Cleaning the bearing


  1. 5.     Excessive leakage from stuffing box

Possible reasons:  Packing rings excessive worn

                 Shaft sleeve worn

                 Dirty sealing water

Solutions: Replace new packing ring

                 Replace shaft sleeve

                 Change clean sealing water


  1. 6.      Pump vibrates or is noisy

   Possible reasons:  Bearing worn

                     Impeller unbalanced

                     Air entered into suction pipe or blocked

                     Flow rate non-uniform and pump not primed

   Solutions: Replace new bearings

                     Replace new impeller

                     Discharge air and remove block

                     Improve on the pump feeding
