CAT Pumps 2SF05SEEL 2SF-Series Plunger Pump

The CAT Pumps 2SF05SEEL is an ultra-compact, industrial-duty direct-drive triplex plunger pump from the highly regarded 2SF Series. Engineered specifically for high-pressure fluid delivery in demanding and corrosive environments, this positive displacement pump is constructed with a robust 316 Stainless Steel manifold and valve assemblies. This premium metallurgy provides superior structural integrity and exceptional chemical compatibility, making it an ideal choice for continuous-duty applications such as reverse osmosis, seawater desalination, and specialized chemical transfer systems.

Designed to maximize operational efficiency and component longevity, the 2SF05SEEL operates at a precise flow rate of 0.5 GPM with a maximum pressure capacity of 1200 PSI. It features advanced, concentric solid ceramic plungers that provide a true wear surface, significantly extending the life of the standard NBR (Buna-N) seals. The pump utilizes a hollow-shafted configuration designed to bolt directly to a standard 56C-face electric motor, providing a space-saving installation without the need for external belts or pulleys. By minimizing internal friction and utilizing premium wetted components, this plunger pump delivers the highly consistent, reliable performance required for specialized high-purity fluid systems.
