Froth pumps are of heavy duty construction, designed for continuous pumping of highly abrasive and corrosive frothy slurry. They have a vertical shaft configuration, and comprise a hopper, with vertical Bearing Assembly, and Type‘NP-AF’ pump wet-end. They feature a wide choice of replaceable abrasion resistant metal or moulded elastomer casing liners and Impellers.
AF froth pump has been designed to increase the pump ability of frothy slurry. The principle of operation is similar to that of hydrocyclone separation. Air is separated from the 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.
Standard pumps are supplied with parts in wear resistant Natural Rubber or High Chrome Iron Alloy, with a nominal hardness. Other wear part materials available. The wear parts have large material sections for extra longwear life and are designed for the toughest applications.
