PA401X / PA 401X Fluid-o-Tech 140 GPH 2.33 GPM Standard Bypass Compact Brass Rotary Vane Pump

Fluid-o-Tech PA 401X Brass Rotary Vane Pump

The Fluid-o-Tech PA 401X is a highly reliable positive displacement rotary vane pump from the versatile PO 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 nominal maximum flow rate of approximately 144 GPH (2.4 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.

What sets the PA 401X apart from the standard PA 401 model is the addition of a built-in 70-mesh (75-micron) strainer. This integrated filtration screen provides critical frontline defense, protecting the internal carbon graphite pumping chamber and vanes from damaging particulates without requiring a bulky external pre-filter assembly. Designed for maximum system safety and ease of installation, this pump also features a Standard Internal Bypass Valve to regulate pressure spikes. It seamlessly mounts to standard NEMA 48Y electric motors using an industry-standard Carbonator Clamp and utilizes standard 3/8" NPT threaded ports.
