PA111 / PA 111 Fluid-o-Tech 45 GPH 0.75 GPM Standard Bypass Stainless Steel Rotary Vane Pump

The Fluid-o-Tech PA 111 is a durable, highly compact positive displacement rotary vane pump engineered for reliable, continuous commercial operation. Distinguished by its robust stainless steel housing, this pump provides superior corrosion resistance for applications involving mildly aggressive fluids, deionized water, or those requiring strict high-purity standards. It serves as an optimal fluid transfer solution for commercial reverse osmosis (RO) systems, cooling circulation loops, espresso machines, and laboratory water treatment setups.

Utilizing a stainless steel rotor and long-lasting carbon graphite vanes, this pump ensures a smooth, pulsation-free flow. Designed for direct clamp mounting to an external motor, it operates efficiently to deliver a nominal flow rate of 45 gallons per hour (GPH) at a standard test pressure of 100 PSI and 1725 RPM. The PA 111 is equipped with a built-in, adjustable bypass relief valve, allowing operators to easily regulate discharge pressure and protect the hydraulic circuit from unexpected pressure spikes. Built for rigorous demands, it safely handles a maximum operating pressure of 230 PSI and liquid temperatures up to 158°F (70°C), while only requiring a 1/4 HP motor to reach outputs of 200 PSI.
