This is a triplex [three plunger rods] positive displacement, reciprocating, plunger pump, constructed of 316SS manifolds, 316SS valve assemblies, solid ceramic plungers and standard NBR [Buna-N] seals and o-rings. These higher capacity plunger pumps are suitable for multi-gun and multi-nozzle, industrial high pressure systems and pumping special liquids such as DI water and salt water.
