PB301 / PB 301 Fluid-o-Tech 100 GPH 1.67 GPM Standard Bypass Standard No Lead Brass Rotary Vane Pump

Fluid-o-Tech PB 301 Rotary Vane Pump

The Fluid-o-Tech PB 301 is a premium positive displacement rotary vane pump from the highly versatile PO/PA/PB 70-400 Series. What specifically sets the PB series apart from the standard PA series is its Low-Lead / No-Lead Brass housing. This construction makes the pump fully compliant with strict drinking water regulations (such as NSF 169), ensuring it is safe for high-end commercial espresso machines, potable water dispensers, and reverse osmosis systems where water purity is critical. It delivers a reliable nominal flow rate of approximately 100 GPH (300 LPH) at standard motor speeds, providing excellent capacity for multi-group beverage equipment.

Engineered for longevity and consistent performance, this model utilizes standard 3/8" NPT inlet and outlet ports and the industry-standard Carbonator Clamp interface for quick, secure mounting to NEMA 48Y motors. It is equipped with a Standard Internal Bypass Valve, which allows the operator to easily adjust the working pressure while simultaneously protecting the pump and the broader system from over-pressurization events. With a durable stainless steel rotor and self-lubricating carbon vanes, the PB 301 provides smooth, pulsation-free flow even under demanding, continuous-duty commercial conditions.
