PA2511 / PA 2511 Fluid-o-Tech 90 GPH 1.50 GPM Standard Bypass Stainless Steel Rotary Vane Pump

Fluid-o-Tech PA2511 Brass Rotary Vane Pump (66 GPH, Standard Bypass)

The Fluid-o-Tech PA 2511 is a high-capacity positive displacement rotary vane pump belonging to the robust PO/PA 2000-4000 Series. Constructed with a durable Brass housing, this model is engineered to deliver high flow rates for demanding commercial applications, such as large-scale reverse osmosis systems, car wash recirculation, and industrial cooling circuits. Unlike smaller espresso-style pumps, the 2500 series provides a substantial volume of water while maintaining the quiet, pulsation-free operation characteristic of rotary vane technology.

This specific model delivers a nominal flow rate of 2,500 LPH (660 GPH), making it one of the more powerful brass options in the Fluid-o-Tech lineup. It comes equipped with 1/2" NPT inlet and outlet ports to handle the increased fluid volume and is designed to mount to standard motors using a Clamp Mount (or compatible flange adapter depending on the specific motor bell housing). The "11" configuration typically indicates the presence of an internal adjustable bypass valve, allowing for system pressure regulation and safety relief directly at the pump head.
