CAT 3531CHS (Flushed Stainless Steel Plunger Pump)
Product Description
The CAT Pumps Model 3531CHS is an industrial-grade, 35-Frame triplex plunger pump designed for high-capacity, heavy-duty applications. It is constructed with a durable 316 Stainless Steel manifold and solid ceramic plungers, providing superior corrosion resistance for demanding tasks like high-volume reverse osmosis, saltwater injection, and chemical processing.
The key feature of the 3531CHS is its flushed inlet manifold (indicated by the 'C'), which allows for an external liquid source to provide added lubrication and cooling to the seals when pumping low-lubricity liquids (like deionized water) or high-temperature fluids. Rated for a maximum continuous flow of 36 GPM and pressure up to 1,200 PSI, this pump ensures high efficiency, low pulsation, and extended seal life, making it a reliable choice for continuous industrial operation.
