PA401F / PA 401F Fluid-o-Tech 140 GPH 2.33 GPM Standard Bypass Standard Brass Rotary Vane Pump

PA 401F Rotary Vane Pump – Brass, Flange Mount, 400 L/hr (105 GPH) @ 145 PSI, NBR Seal, Positive Displacement Pump with Relief Valve

The Fluid-o-Tech PA 401F is a highly reliable positive displacement rotary vane pump belonging to the versatile PO/PA 70-400 Series. Built with a durable, corrosion-resistant Brass housing and a stainless steel AISI 303 rotor, this pump is expertly engineered for pumping water and moderately aggressive liquids at low flow and high pressure. Delivering a maximum flow rate of approximately 140 GPH (2.3 GPM) at standard 60Hz motor speeds, it is widely utilized across commercial reverse osmosis (RO) systems, post-mix beverage dispensers, espresso coffee machines, and advanced water treatment networks.

Engineered for continuous-duty applications, the PA 401F is a Flange Mount ("F") model. This means it utilizes a specialized bolt-on flange for direct and highly secure coupling to compatible electric motors, providing a more rigid connection than a standard band clamp setup. Designed for maximum system safety, this pump features a Standard Internal Bypass Valve to carefully regulate the system and protect the internal plumbing from unexpected pressure spikes. It operates quietly and provides pulsation-free flow, utilizing standard 3/8" NPT threaded ports for secure integration into high-pressure liquid transfer systems.
