2SF42SEEL CAT Pump 4.2 GPM / 15.9 LPM 1200 PSI 316 SS Direct Drive

Cat Pumps 2SF42SEEL Stainless Steel Triplex Plunger Pump (4.2 GPM, 1200 PSI)

The CAT Pumps 2SF42SEEL is a highly efficient, industrial-duty direct-drive triplex plunger pump belonging to the renowned 2SF Series. Engineered for high-pressure fluid transfer in highly corrosive and demanding environments, this positive displacement pump features a wetted end constructed entirely of 316 Stainless Steel. This premium metallurgy ensures maximum structural integrity, exceptional chemical compatibility, and long-lasting durability, making it an industry standard for continuous-duty applications such as reverse osmosis, seawater desalination, industrial misting, and specialized chemical injection systems.

Designed to deliver precise and reliable performance, the 2SF42SEEL operates at a steady flow rate of 4.2 GPM with a maximum pressure capacity of 1000 PSI. It incorporates advanced, concentric solid ceramic plungers that provide a true, low-friction wear surface, substantially extending the operational life of the standard NBR (Buna-N) seals. Utilizing a space-saving, hollow-shafted configuration, this pump is designed to bolt directly to a standard NEMA 56C-face electric motor. By eliminating the need for external belts, pulleys, and mounting plates, this compact direct-drive assembly delivers the highly consistent, continuous-duty operation required for mission-critical liquid handling systems.
