PA411 / PA 411 Fluid-o-Tech 140 GPH 2.33 GPM Standard Bypass Stainless Steel Rotary Vane Pump

Fluid-o-Tech PA411 Stainless Steel Rotary Vane Pump (144 GPH)

The Fluid-o-Tech PA 411 is a high-performance positive displacement rotary vane pump belonging to the renowned PO/PA 70-400 Series. Engineered for medium-flow fluid transfer applications, this model is constructed with a robust Stainless Steel (AISI 303) housing and rotor. This premium metallurgy offers exceptional durability and superior corrosion resistance, making it an ideal choice for handling purified water and moderately aggressive liquids in commercial reverse osmosis (RO) systems, ultra-filtration setups, and industrial cooling loops where standard brass components are unsuitable.

Designed for continuous-duty reliability, the PA 411 features a high-density carbon graphite internal pumping chamber and vanes that ensure a smooth, pulsation-free flow. It utilizes a standard Carbonator Clamp Mount for secure, direct coupling to compatible NEMA 48Y or 56C motors using a stainless steel V-band clamp. Delivering a robust maximum flow rate of 144 GPH (approx. 545 LPH) at 60Hz, it can safely operate at pressures up to 260 PSI. Additionally, it is equipped with a Standard Bypass Relief Valve to precisely manage extraction pressures and protect downstream plumbing from unexpected pressure spikes.
