AF™ T Series multi-stage liquid ring vacuum pumps utilize the same axial flow design as the A Series single stage pumps with an additional stage to achieve deeper vacuum levels. When packaged in oil sealed systems, T series pumps can operate in dry gas applications to vacuum levels as low as 4 Torr (5.3 mbar a).
This patented pump style is designed for high wet vacuum applications where they can operate with the lowest partial gas pressure without cavitation. Ideally suited for evaporators, deaerators, autoclaves, dryers and other applications requiring vacuum higher than 27"Hg. Available in closed coupled motor configuration.
Show more about how AF™ Liquid Ring Pumps work
AF™ series vacuum pumps consist of a shrouded motor rotating freely within an eccentric casing. Centrifugal force acting on liquid within the pump causes the liquid to form a ring inside the casing. A fixed port cylinder concentric with the rotor directs the gas into the suction ports.
Gas is trapped between the blades by the liquid pistons formed by the centrigual force as the liquid receds from the port cylinder. It is rapped at the point of maximum eccentricity and is then compressed by the liquid ring as it is forced radially inward toward the central port cylinder. After each revolution the compressed gas and accompanying liquid are discharged.
During the pumping cycle the gas is in intimate contact with the sealing liquid and compression is nearly isothermal. When handling saturated vapor-gas mixtures the liquid ring acts as a condenser greatly increasing the effective capacity of the pump.
