Positive Displacement Pumps
Positive displacement pumps are a type of pump that moves a constant volume of fluid with each revolution or cycle of the pumping mechanism. Unlike centrifugal pumps, which transfer fluid using centrifugal force, positive displacement pumps create a vacuum and force the fluid to move by trapping a fixed amount and forcing it through the discharge valve. These pumps are widely used in various industries due to their ability to handle a wide range of fluid viscosities and generate high discharge pressures.
