PB1001 / PB 1001 Fluid-o-Tech 320 GPH 5.33 GPM Standard Bypass High Volume Stainless Steel Rotary Vane Pump

1,000 L/h Clamp-Mount Vane Pump with Built-In Relief Valve for Beverage, Water Treatment and Booster Systems

The Fluid-o-Tech PB1001 is the highest-flow model in the PO 500-1000 high-volume series, rated at 1,000 L/h (264 GPH) at 1450 RPM. On a 1725 RPM motor it delivers about 320 GPH (5.33 GPM). It is a positive displacement rotary vane pump with a low-lead brass housing, a clamp mount, and a built-in relief valve.

PB pumps are NSF 169 listed and meet the low-lead requirements of California AB 1953, which makes this version a fit for drinking water and beverage equipment. The rotor is AISI 303 stainless steel, the pumping chamber and vanes are carbon graphite, and the seal is NBR (Buna-N). Ports are 1/2-inch NPT. The pump clamps directly to a 48YZ-frame motor and is driven through a slotted shaft with a brass key. Fluid-o-Tech makes adapter sets for NEMA 56C, M71 and M80 motors.

Maximum static pressure is 290 PSI (20 bar), maximum differential pressure is 230 PSI (16 bar), and the liquid temperature limit is 158°F (70°C). The relief valve is adjustable and is factory set at 170 PSI (12 bar) unless a different setting is requested. It guards against overpressure and is not meant to regulate flow. Fluid-o-Tech recommends a 10-micron filter ahead of the pump and warns against running it dry. Main applications are post-mix drink dispensers, cooling systems, booster systems, and water treatment, including reverse osmosis and ultrafiltration.
