CAT Pumps 781.4410 8PFR1 Plunger Pump
Product Description
The CAT Pumps 781.4410 is an 8-Frame Triplex Plunger Pump built for rugged industrial applications requiring high pressure and moderate flow. As a Model 781 variant, this pump delivers a maximum flow of 4.7 GPM at a powerful maximum pressure of 5,000 PSI.
The pump features a highly corrosion-resistant fluid end constructed with a 316 Stainless Steel block-style manifold, 316 Stainless Steel valve assemblies, and durable Solid Ceramic Plungers. This configuration is ideal for use with aggressive liquids, including saltwater, industrial chemicals, and high-purity water systems.
Crucially, the .4410 suffix denotes an upgrade to the seal material for enhanced chemical resistance: it utilizes Special Blend PTFE high and low-pressure seals with FPM (Viton) O-Rings, allowing for maximum fluid temperatures up to 200∘F (93∘C). The triplex plunger design ensures high efficiency, low pulsation, and extended seal life, making it a dependable choice for demanding industrial and mobile applications.
