PA 3501 / PA3501 Fluid-o-Tech 125 GPH 2.08 GPM Standard Bypass Compact Brass Rotary Vane Pump

Fluid-o-Tech PA 3501 Rotoflow Rotary Vane Pump

The Fluid-o-Tech PA 3501 is a high-capacity, positive displacement rotary vane pump designed for precision fluid transfer at high pressures. As part of the renowned Rotoflow® series, this pump is engineered for continuous duty in demanding commercial and industrial environments, providing a smooth, pulse-free flow that is essential for sensitive systems.

The PA designation confirms the inclusion of an integrated, adjustable bypass valve, which provides critical over-pressure protection by recirculating fluid within the pump head when system limits are reached. Constructed with a heavy-duty brass housing and a stainless steel AISI 303 rotor, the PA 3501 utilizes self-lubricating carbon graphite vanes to ensure a long operational life with minimal maintenance. Its clamp-mount design allows for quick and secure attachment to standard motors, making it a versatile choice for high-volume reverse osmosis (RO) systems, cooling circuits, and beverage carbonation applications.
