Positive displacement pumps are available in a wide variety such as gear, lobe, piston, diaphragm, peristaltic, screw, progressive cavity, hydraulic and many others. Their advantages are:
Positive Displacement pumps operate by using a rotary, reciprocating, or diaphragm method of drawing fluid into the pumping chamber at the inlet and pushing it through a discharge outlet. Positive Displacement pumps move fluid at a constant rate regardless of pressure conditions, and they are typically the preferred choice for low to moderate flow rates at higher discharge pressures.
