AF® Series Liquid Ring Vacuum Pumps

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.

AF® Series Motor mounted single stage liquid ring vacuum pumps

• Flat power curve over entire vacuum range prevents motor overload.
• Reduced stress on motor shaft and bearings.
• Increased water handling capability prevents heat build-up, extends life of mechanical seals.
• Compact, close - coupled design eliminates need for interstate manifold or motor alignment.

Cavitation: AF pumps are not as susceptible to cavitation compared to flat plate design because the flow path through the pump is an axial flow. This flow allows the velocity through the pump to be unchanged and carries the air out effortlessly.

Performance data based on 68°F inlet air with 50% relative humidity and using water as a sealant at 60°F.
