Fluid-o-Tech PA 3511F High-Flow Brass Rotary Vane Pump with Bypass Valve

The Fluid-o-Tech PA 3511F is a powerful brass rotary vane pump belonging to the high-capacity Rotoflow® line. This pump is engineered for large commercial and industrial systems requiring smooth, pulse-free fluid output up to 900 LPH (238 GPH) at moderate to high pressures.

The PA prefix confirms that this model includes a built-in, adjustable bypass/relief valve, which is essential for safely controlling the maximum discharge pressure and protecting the system and motor. The Flange Mount ('F') design ensures a stable, robust connection directly to a compatible motor shaft. Constructed with a durable brass housing, stainless steel rotor, and carbon graphite internals, the PA 3511F is widely used in high-volume reverse osmosis boost systems, large carbonators, chillers, and chemical metering systems involving non-aggressive liquids.

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.
