PA104 / PA 104 Fluid-o-Tech 45 GPH 0.75 GPM Balanced Bypass Compact Brass Rotary Vane Pump
Fluid-o-Tech PA 104 (Brass Rotary Vane Pump)
The Fluid-o-Tech PA 104 is a compact, positive displacement rotary vane pump engineered for high-pressure, low-flow applications that demand consistent and pulsation-free performance. Part of the PO/PA series, this pump features a robust brass housing (often lead-free, depending on the version) with a stainless steel rotor and durable carbon graphite vanes.
The PA 104 is rated for a nominal flow rate of approximately 40 Gallons Per Hour (GPH) and can handle a maximum static pressure up to 290 PSI (20 Bar). It is frequently used in commercial Reverse Osmosis (RO) systems, ultra-filtration, espresso coffee machines, and water dispensers. Designed for direct mounting to a motor using a standard stainless steel clamp, the pump's consistent pressure output and quiet operation make it a preferred choice for reliable, long-service-life fluid transfer.
