Priming Pump Is Not Provided With All Centrifugal Pumps:

  • If the suction head of a centrifugal pump is positive or if the pump is used for circulating purpose then priming pump is not required.
  • When the suction head is positive as soon as opening the suction valve the system including suction line is filled with water, this water expels the air in suction side.
  • When the pump is in use of circulation, there almost the same thing happens, so priming is not required or has a very effectiveness.
