PA401 / PA 401 Fluid-o-Tech 140 GPH 2.33 GPM Standard Bypass Compact Brass Rotary Vane Pump

Fluid-o-Tech PA401 Brass Rotary Vane Pump (Clamp Mount, 400 L/h)

The Fluid-o-Tech PA401 is a precision-engineered, positive displacement rotary vane pump designed for high-performance fluid transfer in industrial and commercial applications. As a cornerstone of the Fluid-o-Tech PO/PA 70-400 series, this pump features a robust lead-free brass housing and a stainless steel (AISI 303) rotor, ensuring durability and corrosion resistance. The internal pumping chamber is constructed from high-density carbon graphite, which provides a self-lubricating, low-friction wear surface that facilitates smooth, consistent liquid delivery. This advanced internal architecture is specifically engineered to maintain structural integrity under continuous-duty cycles, making it the industry standard for reverse osmosis (RO) systems, post-mix beverage dispensing, and specialized industrial water treatment circuits.

Engineered to prioritize operational reliability and efficiency, the PA401 delivers a nominal flow rate of approximately 140 GPH (gallons per hour) at standard operating speeds. It includes a factory-integrated relief valve (bypass) that protects the hydraulic system from over-pressurization and allows for fine-tuned pressure control. The pump utilizes a standard carbonator clamp (V-band) mounting configuration, enabling direct, secure coupling to NEMA 48Y or 56C electric motors. With its 3/8" NPT(F) inlet and outlet ports and optimized flow dynamics, the PA401 provides the steady, non-pulsating pressure required for mission-critical liquid handling.
