Knowledge & Insights: Positive Displacement Pumps

Rotary Positive Displacement Pumps

Last month we discussed the internal operation of reciprocating pumps, one of two types of positive displacement pumps. This month we will analyze how the other type of PD pump – rotary pumps. Rotary pumps have rotating gears instead of the backward and forwards motion of cylinders like reciprocating pumps. In some cases, they can […]

What Exactly Is A Positive Displacement Pump?

Positive Displacement (PD) Pumps work by trapping a fixed amount of fluid, then displacing or forcing it into the discharge pipe. PD Pumps are engineered to use a reciprocating, rotary or diaphragm method to move a variety of fluids. These pumps are most commonly used for pumping viscous liquids and those that contain fragile solids. PD […]
