PB3501 / PB 3501 Fluid-o-Tech 125 GPH 2.08 GPM Standard Bypass Standard No Lead Brass Rotary Vane Pump

Fluid-o-Tech PB 3501 Low-Lead Brass Rotary Vane Pump (125 GPH, Standard Bypass)

The Fluid-o-Tech PB 3501 is a high-performance positive displacement rotary vane pump belonging to the renowned PO/PA/PB 70-400 Series. The PB series is specifically distinguished by its Low-Lead / No-Lead Brass housing, ensuring full compliance with stringent drinking water standards (such as NSF 169 and California AB 1953). This specialized construction makes the PB 3501 exceptionally safe and highly sought after for commercial espresso machines, post-mix beverage dispensers, and advanced reverse osmosis (RO) drinking water systems. It reliably delivers a flow rate of approximately 125 GPH (2.08 GPM), providing steady, high-capacity water output for demanding commercial applications.

Engineered for continuous duty and quiet, pulsation-free operation, this compact pump features a durable stainless steel AISI 303 rotor combined with self-lubricating carbon graphite internal vanes. The PB 3501 utilizes standard 3/8" NPT inlet and outlet ports, and it is designed to securely mount to a standard NEMA 48Y motor using an industry-standard Carbonator Clamp. Additionally, it is equipped with a built-in Standard Internal Bypass Valve, which allows operators to easily regulate the operating pressure while safeguarding the internal components and plumbing from unexpected pressure spikes.
