Five things you likely didn't know about rotary PD pumps:

  1. PD pumps don't develop head like centrifugal pumps: they move flow.
  2. The flow rate of a PD pump‚ unlike a centrifugal pump‚ increases as the fluid viscosity increases.
  3. PD pump performance is not dependent on specific gravity‚ unlike centrifugal pumps.
  4. Rotary PD pump performance is not governed by the BEP like centrifugal pumps.
  5. Unlike centrifugals‚ most PD pumps are self-priming and can pull almost a pure vacuum.
