CAT Pump Model 2530E Plunger Pump 25 GPM @ 1025 RPM Pressure 100-1200 PSI


Model: 2530E

This triplex (three plunger rods) positive displacement, reciprocating plunger pump is constructed with chrome-plated brass manifolds, 304 stainless steel valve assemblies, solid ceramic plungers and standard NBR (Buna-N) seals and O-rings.

This pump also features a durable blue two mil epoxy paint treatment on the crankcase, rear cover and bearing covers and a unique liquid gasket between the crankcase and manifold to seal moisture out.


• Triplex plunger design ensures high efficiency and low pulsation.
• Durable high-pressure seals are lubricated and cooled by pumped liquid.
• Preset low-pressure seals provide secondary protection against external leaks and require no packing adjustments.
• Belt-driven option provides precision flow setting.
• Direct-drive option offers a compact footprint for SAE hydraulic motors with a bell housing/flexible coupler assembly.
• Model 2531C offers an external flush for high-temperature or low-lubricity liquids.
• Pump comes standard with NBR seals. Alternative seal materials are available for higher temperature or chemical compatibility.
