Eccentric disc pumps work to pump liquids by spinning an off-center disc inside of a pump housing. As the disc spins around inside the housing two low pressure and two high pressure zones are formed. These opposite high and low pressure zones move fluid through the pump. Because the volumes of these pressure zones is known, a constant, regular, measured flow rate can be achieved by varying the speed of the pumps spinning. This consistent flow is necessary for accurate chemical processing or distributors.
Because eccentric disc pumps are by design seal-less, fluids that would react with or corrode common seal materials are able to be pumped through a processing line. By protecting against unintended reactions valuable chemical materials are preserved saving the processing facility in materials costs.
