2SFQ25SEEL Cat Pump 2.5 GPM / 9.5 LPM 1200 PSI 1725 RPM 316 Stainless Steel Triplex Positive Displacement Plunger Direct Drive 3/8" NPT(F)

Cat Pumps 2SFQ25SEEL 316 Stainless Steel Direct-Drive Plunger Pump (2.5 GPM, 1200 PSI)

The CAT Pumps 2SFQ25SEEL is a specialized, industrial-duty direct-drive triplex plunger pump from the highly regarded 2SFQ Series. Engineered to deliver highly reliable fluid transfer while significantly reducing operational noise, this "Quiet" series positive displacement pump features a wetted end constructed entirely of 316 Stainless Steel. This premium manifold metallurgy ensures exceptional structural integrity and high chemical compatibility, making it an ideal choice for continuous-duty applications such as large industrial reverse osmosis, seawater desalination, and specialized chemical injection systems where both corrosion resistance and lower decibel levels are critical priorities.

Designed to maximize uptime and operational efficiency, this model utilizes a precision-engineered 5/8" hollow shaft configuration that allows it to bolt directly to a standard NEMA 56C-face electric motor, completely eliminating the need for external belts, pulleys, and mounting plates. It operates at a consistent flow rate of 2.5 GPM with a maximum pressure capacity of 1200 PSI. Factory-equipped with standard NBR (Buna-N) seals and O-rings, the pump safely accommodates continuous liquid temperatures up to 160°F. By combining a true low-friction wear surface via concentric solid ceramic plungers with a compact, noise-reducing footprint, this plunger pump delivers consistent, reliable performance for high-purity fluid systems.
