🧪 CAT Pumps 3811HS Stainless Steel Plunger Pump

The CAT Pumps 3811HS is a heavy-duty 38-Frame Block-Style Triplex Plunger Pump engineered for continuous, high-capacity fluid transfer in harsh industrial environments. Constructed with a highly durable 316 Stainless Steel block-style manifold and valve assemblies, this positive displacement pump provides exceptional corrosion resistance and high strength. This specialized construction makes it the premier choice for handling aggressive fluids, industrial chemicals, and demanding high-pressure applications where standard brass pumps would quickly degrade.

Operating at an efficient 800 RPM, the 3811HS delivers a substantial continuous flow rate of 14.0 GPM at 3000 PSI. Its advanced triplex design ensures smooth, low-pulsation performance, which is critical for protecting sensitive downstream components in large-scale fluid networks. Outfitted with reliable Buna-N (NBR) seals, it safely handles elevated liquid temperatures, while the robust block-style manifold design maximizes structural integrity for continuous-duty operations and reduces the frequency of maintenance.
