AK series foam pumps are high efficiency and energy saving products, the type of pump can partially eliminate the foam in the slurry when working, the transmission capacity is far more than other types of products, and does not require any shaft seal and shaft seal water, is the ideal type of pump for conveying foam slurry. The structure of the pump head part is similar to the structure of AA slurry pump, it is a double pump shell structure, the flow parts are made of hard nickel, high chromium or rubber materials, and the transmission part is common with the Warman AB and ABR type pump transmission part. The funnel-shaped material box is a steel plate structural part, and can be covered with a lining on the inner wall of the material box according to the different conveying medium. The outlet position of the pump can be installed and used at a 45° interval and rotated at eight different angles. The pump has the advantages of excellent performance, convenient disassembly and high reliability.
