PA611 / PA 611 Fluid-o-Tech 195 GPH 3.25 GPM Standard Bypass High Volume Stainless Steel Rotary Vane Pump

The Fluid-o-Tech PA611 is a high-capacity, positive displacement rotary vane pump designed for high-flow and high-pressure fluid transfer in demanding commercial applications. As a member of the PO/PA 500-1000 Series, this pump features a robust AISI 303 Stainless Steel housing and rotor, offering exceptional corrosion resistance and structural durability. The internal pumping chamber and precision vanes are constructed from high-density carbon graphite, providing a self-lubricating surface that ensures smooth, pulsation-free liquid output and quiet performance. It is an industry-standard component widely specified for reverse osmosis (RO) systems, ultra-filtration, industrial cooling loops, and high-volume water boosting systems.

Engineered for operational reliability, the PA611 delivers a nominal flow rate of approximately 190 GPH (at 1725 RPM) and is equipped with an integrated, adjustable bypass relief valve. This valve is critical for protecting the pump and downstream hydraulic components from unexpected pressure spikes and allows for fine-tuned pressure regulation. The pump utilizes a standard carbonator clamp (V-band) mounting configuration, enabling secure, direct coupling to compatible NEMA 48Y or 56C electric motors. With its optimized flow dynamics and durable construction, this pump provides the consistent, non-pulsating pressure required for mission-critical commercial and industrial equipment.
