We are an Authorized Distributor for Cat Pumps
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.
