DF (DHF) series vertical froth pump or centrifugal foam pump are designed with double casing design, including rubber lined froth pump, centrifugal pump, mining froth pump. These centrifugal foam pumps feature high efficiency, wear-resistance, stable performance and great interchangeability. The material of liner and impeller is wear-resistant metal or rubber. The centrifugal froth/foam pumps do not need sealing, and the hopper can use liners. They may deliver the slurries of more flow and higher head with small installation space. The vertical froth pumps may be driven by belt or direct coupling. DF (DHF) series centrifugal foam pump should rotate clockwise viewing from the drive end.
Application of Vertical Froth Pump
Centrifugal foam pump can be used for the flotation industrial process, ideal for delivering foaming slurries.
Feature of Vertical Froth Pump
Froth pump is suitable for transporting slurry with froth, especially for flotation processing .It can eliminate the froth or foam in the running slurry and work normally even if the feeding slurry is not enough. The pump wet parts are made of Ni-hard and high chromium wear-resistant alloy materials. Funnel charging box is of steel structure. It can be lined according to different kinds of material. The discharge direction of pump can be oriented at intervals of 45°.This series of rubber lined froth pump adopts double-casing structure, with stable performance, high efficiency; wear resistance, and great interchangeability of components. The materials of liner and impeller can adopt anti-wear metal or rubber.
