CAT Pumps 1531 Stainless Steel Plunger Pump

 

The CAT Pumps 1531 is a heavy-duty 15-Frame Triplex Plunger Pump engineered for continuous, high-capacity fluid transfer. Constructed with a highly durable 316 Stainless Steel manifold and valve assemblies, this positive displacement pump provides exceptional corrosion resistance. This specialized construction makes it the premier choice for handling aggressive fluids, such as deionized (DI) water, saltwater in Reverse Osmosis (SWRO) desalination systems, and harsh industrial chemicals that would rapidly degrade standard brass pumps.

Operating at an efficient 1450 RPM, the 1531 delivers a massive continuous flow rate of 15.6 GPM at 1500 PSI. Its advanced triplex design ensures smooth, low-pulsation performance, which is critical for protecting sensitive downstream components in high-purity processing and multi-nozzle industrial networks. Outfitted with standard factory NBR (Buna-N) seals, it safely handles liquid temperatures up to 140°F (60°C), while maintaining excellent durability and minimal maintenance requirements thanks to its easily serviceable "wet end" that can be accessed without entering the crankcase.
