PA 810 / PA810 Fluid-o-Tech 260 GPH 4.33 GPM No Bypass High Volume Stainless Steel Rotary Vane Pump PA0800BN0NN0000

Fluid-o-Tech PA 810 Rotary Vane Pump

The Fluid-o-Tech PA 810 is a high-capacity positive displacement rotary vane pump from the PO/PA 500-1000 series. Unlike the standard brass models, the PA 810 features a robust Stainless Steel (AISI 303) housing, making it the preferred choice for handling aggressive fluids, ultra-pure water, and sanitary applications where brass is not suitable. It is widely utilized in commercial reverse osmosis (RO) systems, chemical circulation, and high-purity cooling loops.

This specific model is designed with a Carbonator Clamp mounting interface for secure attachment to NEMA 48Y motors (via V-band clamp) or IEC motors with an adapter. It delivers a substantial flow rate of approximately 260 GPH (Gallons Per Hour) when operated at standard motor speeds. Notably, the PA 810 is a non-bypass unit, meaning it does not contain an internal relief valve; therefore, an external safety relief valve or pressure regulator must be installed in the system line to protect against over-pressurization.

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.
