PA311F / PA 311F Fluid-o-Tech 100 GPH 1.67 GPM Standard Bypass Stainless Steel Rotary Vane Pump

Fluid-o-Tech PA 311 F Brass Rotary Vane Pump (80 GPH, Flange Mount)

For commercial fluid transfer applications that require consistent, pulsation-free pressure, reliable component engineering is critical. The Fluid-o-Tech PA 311 F is a compact, positive displacement rotary vane pump designed specifically for continuous-duty commercial operation. Constructed with a robust brass housing, this pump provides excellent durability for standard fluid transfer tasks. It serves as an optimal solution for commercial beverage dispensers, espresso machines, cooling circulation loops, and light water treatment setups that require precision flow control.

Inside the pump housing, a high-precision AISI 303 stainless steel rotor and long-lasting carbon graphite vanes work in tandem to ensure a smooth, highly efficient output. Engineered for direct flange mounting to an external motor, the PA 311 F operates efficiently to deliver a nominal flow rate of 80 gallons per hour (GPH) at a standard test pressure of 100 PSI and 1725 RPM. It is equipped with a built-in standard bypass relief valve, allowing operators to accurately regulate discharge pressure and safeguard the hydraulic circuit from unexpected pressure spikes. Built for rigorous daily demands, it safely handles a maximum operating pressure of 230 PSI and continuous liquid temperatures up to 158°F (70°C), providing an ideal balance of robust construction and precise fluid transfer.
