PA1000AN0NN0000 Fluid-o-Tech 320 GPH 5.33 GPM No Bypass High Volume Brass Rotary Vane Pump

Fluid-o-Tech PA1000AN0NN0000 Brass Rotary Vane Pump – 320 GPH, 5.33 GPM, 290 PSI Max, No Bypass, NSF Compliant

The Fluid-o-Tech PA1000AN0NN0000 is a high-capacity, positive displacement rotary vane pump belonging to the heavy-duty PO 500-1000 Series. Engineered specifically for transferring clean water and water-based solutions at high volumes and elevated pressures, this robust pump features a durable lead-free brass housing. Internally, it utilizes a precision-machined AISI 303 stainless steel rotor paired with a high-density carbon graphite pumping chamber and vanes. This advanced internal metallurgy provides a self-lubricating wear surface, ensuring a smooth, pulsation-free fluid output, exceptionally quiet operation, and long-lasting durability during continuous-duty commercial applications.

Designed to maximize operational reliability for larger systems, the PA1000AN0NN0000 delivers a nominal flow rate of 264 gallons per hour (GPH) when operated at a standard 1450 RPM, and scales up to approximately 340 GPH at 1725 RPM. This specific model is configured without an internal relief valve (no bypass), making it highly suitable for systems that strictly manage pressure regulation externally. Utilizing high-flow 1/2" NPT(F) threaded ports and an NSF-approved elastomer seal, it strictly complies with regulations for handling potable water. Featuring a standard carbonator clamp (v-band) mounting configuration, it seamlessly couples to compatible NEMA 48Y or NEMA 56C electric motors, making it a dependable, industry-standard component for high-output reverse osmosis (RO) systems, commercial cooling loops, water treatment facilities, and booster systems.
