Cat Pump Model 1540E Plunger Pump 19.3 GPM @ 1180 RPM, Pressure 100-1200 PSI


Model: 1540E

This triplex (three plunger rods) positive displacement, reciprocating plunger pump is constructed with forged 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.
• Special high-density, polished, concentric plungers provide a true wear surface and extended seal life.
• Preset low-pressure seals provide secondary protection against external leaks and require no packing adjustment.
• Models 1540EC and 1541C offers an external flush for high-temperature or low-lubricity fluids.
• Belt-driven option provides precision flow setting.
• Direct-drive option offers a compact footprint for electric motors with a NEMA or IEC frame, or SAE hydraulic motors with a bell housing/flexible coupler assembly.
• Pump comes standard with NBR seals. Alternative seal materials are available for higher temperature or chemical compatibility
