⚙️ Fluid-o-Tech PA 3511 Rotary Vane Pump
Product Description
The Fluid-o-Tech PA 3511 is a high-volume, positive displacement rotary vane pump engineered for demanding commercial and light-industrial applications requiring consistent, high flow at moderate pressure. This specific model is typically supplied with a Stainless Steel housing, making it highly resistant to corrosion and suitable for demineralized water and aggressive liquids. It is widely used in high-capacity beverage dispensing, large cooling systems, and medium-scale Reverse Osmosis (RO) booster applications. The pump features a built-in adjustable bypass valve to protect the system from unexpected pressure spikes. Utilizing a stainless steel rotor and carbon graphite vanes, the PA 3511 is designed for direct clamp mounting to an external motor and is rated for a maximum static pressure of 290 PSI (20 Bar), ensuring quiet, pulsation-free, and efficient continuous operation.

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.
