Positive Displacement Pumps


 
Positive Displacement (PD) pumps move fluid by repeatedly enclosing a fixed volume and moving it mechanically through the system. The pump action is cyclic and can be driven by gears, pistons, screws, rollers, diaphragms, or vanes. There is a wide variety of pump options narrowed down into two common categories: reciprocating and rotary. R.F. MacDonald Co. offers a great selection of all types of positive displacement pumps manufactured by Blackmer, Viking, Boerger, Wrightflow, and more.
