PA0501BNENN0000 Fluid-o-Tech 165 GPH 2.75 GPM Standard Bypass High Volume Stainless Steel Rotary Vane Pump

Fluid-o-Tech PA0501BNENN0000 Stainless Steel Rotary Vane Pump – 500 L/hr (132 GPH) @ 145 PSI, 260 PSI Max, Built-In Relief Valve, NSF Compliant

The Fluid-o-Tech PA0501BNENN0000 is a high-volume, positive displacement rotary vane pump belonging to the heavy-duty PO/PA 500-1000 Series. Engineered specifically for continuous-duty commercial and industrial fluid transfer, this robust pump features a high-grade stainless steel 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 smooth, pulsation-free fluid flow, exceptionally quiet operation, and long-lasting durability when handling clean water and moderately aggressive liquids.

Designed to maximize operational reliability for larger systems, the PA0501BNENN0000 delivers a robust nominal flow rate of approximately 165 gallons per hour (GPH) when operated at a standard 1725 RPM, safely handling a maximum operating pressure of 230 PSI. This specific model is equipped with an integrated, adjustable internal relief valve (bypass) designed to safely regulate system pressure directly at the pump head and protect against system pressure spikes. 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 standard NEMA 56C electric motors, making it a dependable, industry-standard component for high-output reverse osmosis (RO) systems, commercial cooling loops, and water treatment facilities.
