2SF29SEEL Cat Pump 2.85 GPM 1200 PSI 316 Stainless Steel Direct Drive

CAT Pumps 2SF29SEEL Direct Drive Plunger Pump (316 Stainless Steel, 2.85 GPM, 1200 PSI)

The Cat Pumps 2SF29SEEL is a commercial-grade, direct-drive triplex plunger pump engineered specifically for continuous-duty operation in demanding Sea Water Reverse Osmosis (SWRO) and desalination systems. Featuring a precision-machined 316 stainless steel manifold, this heavy-duty positive displacement pump provides exceptional structural strength and maximum corrosion resistance against harsh saltwater environments and aggressive fluid transfer. The wet-end utilizes concentric, high-density, polished solid ceramic plungers to provide a true wear surface and significantly extend seal life during sustained, cyclic pressure loading.

Designed for uncompromising durability and high-efficiency fluid transfer, the 2SF29SEEL delivers a highly consistent flow rate of 2.85 gallons per minute (GPM) while operating at a standard test pressure of 1200 PSI. It features a compact, direct-drive configuration with a 5/8-inch hollow shaft that mounts seamlessly onto standard NEMA 56C face electric motors, eliminating the need for bulky pulleys or belts in tight marine spaces. Operating at a standard 1725 RPM, it produces a smooth, low-pulsation flow output that is essential for maintaining consistent recovery rates and maximizing the lifespan of commercial reverse osmosis membranes.
