Tobee® AFR Rubber Lined Vertical Froth Pumps are designed to increase the pumpability of corrosive frothy suspensions. The principle of operation is similar to that of hydro- cyclone separation. Air is separated from the corrosive slurry in a vortex created by the impeller rotation and the tangential inlet to the pump’s conical sump. This results in more efficient pumping at higher capacities and a smooth operation, free from pulsations caused by air locking.
Design Features:
√ Integrated unit for layout flexibility.
√ Smooth operation of the open vortex created in the sump and vertical “wet end” inlet prevents air locking.
√ Cantilever design does not require submerged bearings or shaft seals.
√ Bearing assembly with double protection sealing arrangement to prevent ingress of slurry.
√ Wear parts are available in a variety of different materials.
√ Simplified maintenance.
