Fluid-o-Tech PA 071 Brass Rotary Vane Pump with Built-in Bypass Valve
The Fluid-o-Tech PA 071 is a brass rotary vane pump from the Rotoflow® line, renowned for its positive displacement technology that delivers stable, pulsation-free flow at high pressures. Specifically designed for use with water and mildly aggressive liquids, the PA 071 is a common component in commercial reverse osmosis (RO) boost systems, carbonators, espresso machines, and chilling applications.
The PA prefix indicates that this model includes a built-in bypass/relief valve, allowing the operator to adjust the maximum discharge pressure and protect the system from pressure spikes without requiring external plumbing. Constructed with a durable brass housing, a stainless steel rotor, and carbon graphite vanes, the PA 071 is engineered for direct motor coupling via a stainless steel clamp, ensuring a compact and reliable footprint.

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.
