The RDP series of Reciprocating Plunger Pumps is suitable for handling most liquids for Oil & Gas, Industrial and Wastewater Treatment applications. RP's RDP pump series are a type of positive displacement pumps where a smooth cylindrical plunger slides through the seal, making it different from piston pumps and allowing higher pressures.
