PB601 / PB 601 Fluid-o-Tech 195 GPH 3.25 GPM Standard Bypass High Volume Stainless Steel Rotary Vane Pump

Low-Lead Brass Pump with Built-In Relief Valve for Beverage and Water Treatment Systems

The Fluid-o-Tech PB601 is a positive displacement rotary vane pump from the PO 500-1000 high-volume series, built with a low-lead brass housing and a built-in relief valve. The PB designation marks Fluid-o-Tech pumps that are NSF 169 listed and meet the low-lead requirements of California AB 1953, so this version suits drinking water and beverage equipment.

The rotor is AISI 303 stainless steel, and the pumping chamber and vanes are carbon graphite. The pump delivers 600 L/h (158 GPH) at 1450 RPM and about 190 GPH (3.1 GPM) at 1725 RPM through 1/2-inch NPT ports. It clamp-mounts directly to the motor and drives through a slotted shaft with a brass key. Seals are NBR (Buna-N).

The PB601 is rated for a maximum static pressure of 290 PSI (20 bar), a maximum differential pressure of 230 PSI (16 bar), and liquid temperatures up to 158°F (70°C). The relief valve is adjustable, and Fluid-o-Tech sets it at 170 PSI (12 bar) unless a different setting is requested. It protects the pump from overpressure and should not be used to regulate flow. Fluid-o-Tech recommends a 10-micron filter ahead of the pump and advises against running it dry. Main applications are post-mix drink dispensers, cooling systems, water treatment, and booster systems.
