CAT Pumps 3537HS Triplex Plunger Pump

 

The CAT Pumps 3537HS is a heavy-duty Triplex Plunger Pump designed for continuous high-load industrial applications. This model is distinguished by its Nickel Aluminum Bronze (NAB) manifold, a specialized alloy that offers superior corrosion resistance compared to standard brass, particularly in environments involving saltwater, brackish water, and compatible chemicals. It is part of the "HS" (High Strength) series, meaning it is built with upgraded connecting rods and plunger rods to withstand the rigorous demands of continuous duty cycles.

As a positive displacement pump, the 3537HS delivers a consistent flow rate of 36 GPM at pressures up to 1,200 PSI, making it a preferred choice for large-scale reverse osmosis (SWRO), saltwater disposal, and wash-down systems in harsh marine environments. The unit features a solid shaft design for universal mounting (belt or direct drive) and comes factory-installed with standard NBR (Buna-N) seals, though the block-style manifold allows for easy field conversion to alternative seal materials if required.
