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.

The PO 70-400 series positive displacement rotary vane pumps are available with brass or stainless steel housings with 3/8” GAS or NPT ports and internal relief valve. The nominal flow rates range between 70 and 400 l/h at 1450 rpm. Any vane pump of this series may be operated at 1725 rpm as well and will provide about 20% more capacity, with a maximum of 530 l/h. Maximum discharge pressure is 16 bar (230 psi). This series mounts directly to NEMA 48Y motors by means of a v-band clamp and to M71, M80 IEC and NEMA 56C motors by means of an adapter and relevant coupling.
