PA311 / PA 311 Fluid-o-Tech 100 GPH 1.67 GPM Standard Bypass Stainless Steel Rotary Vane Pump

Fluid-o-Tech PA 311 Stainless Steel Rotary Vane Pump (111 GPH, Standard Bypass)

The Fluid-o-Tech PA 311 is a high-performance, positive displacement rotary vane pump engineered for precision fluid transfer in commercial reverse osmosis, water treatment, cooling systems, and beverage dispensing applications. Designed to meet stringent hygiene and performance standards, this NSF-listed pump features a robust AISI 303 stainless steel housing that provides exceptional structural integrity and long-lasting corrosion resistance in continuous-duty, high-demand commercial environments.

Internally, the PA 311 is constructed with a precision-machined AISI 303 stainless steel rotor paired with a durable carbon graphite pumping chamber and vanes. This advanced engineering guarantees smooth, self-priming operation and provides natural self-lubricating properties, minimizing internal wear over its operational lifespan. Configured for a standard clamp mount directly to the motor, it features 3/8-inch threaded ports and is equipped with a built-in relief valve to safely regulate system pressure. When driven at a standard 1725 RPM, it delivers a robust nominal flow rate of up to 111 gallons per hour (GPH) and can safely withstand a maximum system pressure of 290 PSI, making it a highly dependable solution for precision fluid management.
