Reliable Sealing Solutions for Positive Displacement Pumps

A positive displacement (PD) pump moves liquids and materials by repeatedly trapping a fixed volume and displacing it into a discharge pipe and through the rest of a system. They are often used to pump viscous materials and operate through a cyclical pumping motion that's driven by pistons, gears or screws.
