Fluid-o-Tech PA 511 Rotary Vane Pump

 

Product Description

 

The Fluid-o-Tech PA 511 is a high-volume, positive displacement rotary vane pump engineered for continuous-duty service in medium-to-large commercial and light industrial systems. Constructed with a standard brass housing, the PA 511 is commonly used in high-demand beverage dispensing, large cooling circuits, and medium-capacity low-pressure Reverse Osmosis (RO) units. It excels at delivering a stable, smooth, and pulsation-free flow, which is vital for maintaining precise system performance. The pump is built for durability, featuring a stainless steel rotor and long-lasting carbon graphite vanes to ensure extended operational life and minimal maintenance requirements. Designed for direct clamp mounting to an external motor, the PA 511 is rated for a maximum static pressure of 290 PSI (20 Bar), providing reliable flow and pressure for systems where efficiency and quiet operation are priorities.

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.
