Pacer's HP series hand dispensing pump is a double acting piston-type which will handle a wide range of solutions. The pump body, valves and valve seats and piston are all made of chemically-resistant, performance engineered plastics, especially compounded to give the pump strength and rigidity. All internal metal parts in contact with the liquid are made of stainless steel. The O-ring and gasket materials are cork-nitrile, Viton® or EPDM.
