🔨 CAT Pumps Model 340 Plunger Pump | 4 GPM / 1800 PSI
The CAT Pumps Model 340 is a durable, industrial-grade 5-Frame Triplex Plunger Pump designed for high-pressure systems such as vehicle wash bays, pressure cleaning, and industrial equipment requiring steady, high-pressure flow. This standard model is built with a rugged Forged Brass manifold for reliability and the best value in a non-stainless steel offering. The pump is designed for Direct Drive applications, typically coupling to a motor at 1725 RPM.
The Model 340 delivers a maximum flow of 4.0 GPM (15 LPM) and can handle pressures up to 1800 PSI (124 bar). Key features that ensure long operational life include pre-set low-pressure seals for secondary leak protection, durable high-pressure seals that are lubricated and cooled by the pumped liquid, and precision-polished Solid Ceramic Plungers for maximum resistance to abrasion and corrosion. The standard pump comes equipped with NBR (Buna-N) seals.
