⚙️ Fluid-o-Tech PA 401 Rotary Vane Pump
Product Description
The Fluid-o-Tech PA 401 is a reliable, positive displacement rotary vane pump designed for continuous and pulsation-free flow, making it ideal for high-precision liquid transfer. This pump features a durable brass housing (often specified as low-lead brass) and a carbon graphite pumping chamber, approved for use with potable water.
The PA 401 delivers a nominal maximum flow rate of approximately () and is rated for a maximum operating pressure up to . This model typically includes a built-in pressure bypass/relief valve for system protection and features a clamp-on mounting style for direct coupling to NEMA 48Y motors. The pump is widely used in commercial Reverse Osmosis (RO) systems, post-mix drink dispensers, carbonators, and general high-pressure water dispensing applications.

The PO 70-400 series positive displacement rotary vane pumps are available with brass or stainless steel housings with 3/8” GAS or NPT ports and internal relief valve. The nominal flow rates range between 70 and 400 l/h at 1450 rpm. Any vane pump of this series may be operated at 1725 rpm as well and will provide about 20% more capacity, with a maximum of 530 l/h. Maximum discharge pressure is 16 bar (230 psi). This series mounts directly to NEMA 48Y motors by means of a v-band clamp and to M71, M80 IEC and NEMA 56C motors by means of an adapter and relevant coupling.
