Plunger & Piston Pump
Plunger and Piston Pump
Pumping of high pressure or with viscous media
Plunger pumps, also often just called piston pump by layman, belong to the group of oscillating positive displacement pumps - one of the oldest pump types. Plunger pumps and piston pumps are reciprocating positive displacement pumps that use a plunger or piston to move media through a cylindrical chamber. They are also called well service pumps, high pressure pumps, or high viscosity pumps because they can deliver high pump pressures and are capable of handling both viscous and solids containing media.
Due to the design, plunger pumps work with efficiencies of more than 90%! This makes their use interesting wherever energy saving is a priority. The high energy density – or small size – of plunger pumps facilitate their installation enormously.
