AF Series Froth Pump



Product Description
The viscous chemical froth produced for mineral processing and oilsand extraction, though necessary, can quickly overwhelm the capabilities of a standard slurry pump. To address this concern, specifically the AF series froth pump to convey frothy, corrosive slurry. Among their many benefits, when working, these pumps can effectively eliminate the foam of slurry weight and can maintain normal function, despite insufficient incoming materials. They are especially suitable for various flotation processes and are also ideal for conveying foamed paste.


Product Features
Main Application
- Heavy-duty construction with through-bolt design provides ease of maintenance and increased productivity
- Casings are fully lined with ductile iron to assure strength, durability, and extended service life
- Large diameter, slow turning, impellers minimize wear and lower TOC
- Large, open internal passages reduce internal velocities, increasing efficiency and reducing operating costs
- Unique impeller design for most difficult froth applications
- Thick elastomer or metal bolt-in liners provide superior corrosion resistance
- Liners can be easily changed and intermixed to prolong the life of the pump and reduce associated maintenance costs
- Minimal shaft/impeller overhang reduces shaft deflection and increases packing life
- The cartridge-style bearing assembly allows for easy maintenance in a clean environment without removal of the pump, minimizing production delays and extending life of bearings
- Standard AH can be converted by replacing cover plate, throat bush, and impeller
- Full flush, low flow, or dry running centrifugal seals conserve water and cut operating costs
As the froth pump gain popularity and promotion, they have become widely used in metallurgical, mining, coal one, and chemical engineering industries, and are relied upon to handle abrasive and corrosive slurries with foam and froth.
