Main Features
1. AF series froth pump newly designed pumps by our factory based on advanced technology from home
and abroad .Being polularized and promoted ;now they are widely used in metallurgical industry .
2. Mining sector ,coal ore and chemical engineering to handle abrasive and corrosive slurries with foam
and froth .when operated , pumps can effectively eliminate foam and froth in slurry and will also
function properly even with inadequate feeding slurry,thus making them the ideal choice for the
delivering foam slurries .esp ,in flotation process.
Model meaning
2QV-AF
2----------------pump discharge (inch)
QV--------------bracket
AF---------------froth pump
Structure features
1. Bearing assembly of AF series in the same with that of SP,SPR series .Bearing housing with motor
base or supporting plate ,i.e.pump and motor are connected either directly with coupling or
through pulley operating conditions.
2. Feeding tank can be steel , stainless steel or coated with rubber with overflow box and tangential
inlet.the former can transmit be excessive incoming slurry back to its pit,while the latter will allow the
slurry quickly get into the pump body and make part of the foams disappear.
3. Double case for AF foam pump ,Wetted parts are metal lined ,rubber lined or of other
non-metallic liner based on you requiring
