Tri-Plex Plunger Pumps

Three piston high pressure pumps, designed to meet the toughest jobs

RR Series - 322

These 3-piston volumetric pumps are designed for use in cleaning units and industrial systems and can be coupled directly to various types of motors or attached with a flexible joint. The pump body and cover are made of durable die-cast aluminum alloy, with a side cover that incorporates an oil sight glass, allowing for easy monitoring of the oil level. The rear cover features an oil drain outlet, and the pump body itself also displays the oil level. The pistons are driven by a crank-connecting rod, with the pump shaft pressed from high-strength steel and equipped with oversized friction bearings. The connecting rods are crafted from a special low-friction zinc-aluminum alloy, while the one-piece ceramic pistons are highly efficient and reliable. The pump head is made of pressed brass and features a double gasket sealing system, while the intake and delivery valves have plugs for easy maintenance.
