Fluid-o-Tech PA 811 Rotary Vane Pump
The Fluid-o-Tech PA 811 is a robust positive displacement rotary vane pump from the high-capacity PO/PA 500-1000 Series. Distinguished by its Stainless Steel (AISI 303) housing, this model is engineered for applications requiring superior corrosion resistance and sanitary performance, such as commercial reverse osmosis (RO) systems, ultra-pure water circulation, and chemical injection. Unlike the brass versions, the stainless steel construction allows it to handle aggressive fluids and demineralized water without leaching contaminants.
Designed for high-volume demands, the PA 811 delivers a nominal flow rate of approximately 260 GPH (1000 LPH) at standard 60Hz motor speeds. It features larger 1/2" NPT inlet and outlet ports to accommodate the increased flow volume and utilizes a Carbonator Clamp interface for secure mounting to NEMA 48Y motors. This model comes equipped with a Standard Internal Bypass Valve, which safeguards the system against over-pressurization and allows for pressure regulation directly at the pump head (typically adjustable up to ~230 PSI).

The PO 500-1000 series positive displacement rotary vane pumps are available with brass or stainless steel housing with ½” GAS or NPT ports and internal relief valve. The nominal flow rates range between 500 and 1000 l/h at 1450 rpm. Any vane pumps of this series may be operated at 1725 rpm as well and will provide about 20% more capacity, with a maximum of 320 GPH. Maximum discharge pressure is 230 psi (16 bar). This series mounts directly to widely available NEMA 48Y motor by means of a v-band clamp and to M71, M80 IEC and NEMA 56C motors by means of an adapter and relevant coupling.
