AF Series Froth Pumps

AF series froth pumps are designed for convey abrasive or corrosive froth slurries more efficiently by de-aerating or partially de-aerating the froth before it enters the pump head, utilising an induced vortex principal. AF Series Froth Pump is a vertical pump complete with vertical shaft configuration and comprise a hopper, with vertical bearing assembly. AF Froth pump utilises frame Plates, Cover Plates and wet parts liners as same as  AH series slurry pumps'. A typical feature of this vertical centrifugal slurry pump is the double-casing design which allows the case to be split open along its centerline. Wet parts are replaceable and made of abrasion resistant high chromium. Depending on yourspecific pumping task, we can rubber and polyurethane to construct the internal pump liner and impeller.

Features of AF Froth Pumps

• The advantages of the pump are of excellent performance, easy assembly & disassembly, high and etc.

• The AF series froth pumps is a efficiency pump are suitable for handing solids-liquid mixture, special for delivering frothy pulp generated in flotation machines in metalliferous and coal flotation circuits.

• The AF froth pump is ideal for all applications involving handling of air entrained slurries, such as flotation froth in base metal concentrators, phosphate and apatite washing plants and calcium carbonate upgrading plants.

• The pump can also be used as a mixing and distribution unit, where dry powder has to be mixed (and wetted) with water. It can also be used with cement in ready mixed concrete and for grouting and injection mixing.



Key Structure of AF Series Froth Pumps

a1

Structure Features:

• The basic principle of the froth pump operation is to de-aerate or partially de-aerate the froth before it enters the pumping. Its handling capacity of the pump is muchhigher than that of other types of slurry pump without shaft seal and sealing water.

• The construction of pump head is double casings slurry pump. All wet-parts can be supplied in Ni-hard, high chrome alloy iron and pressure-moulded natural or synthetic rubber.

• The driver end can be exchanged with that of type--SP(R) pumps. The hopper-tank is fabricated with steel plate. Its inner wall of the tank can be covered with liner according to different medium pumped.

• The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.
