6AHF Heavy Duty Froth Pump for Minerals Froth Handling

Tobee® 6 AHF Heavy-duty Froth Pumps

Tobee® 6 AHF Heavy-duty Froth Pumps are heavy duty horizontal pumps designed to handle difficult tenacious froth.

Tobee® Horizontal Froth Pumps

Tobee® Horizontal Froth Pumps are designed to handle heavy froth. A large oversized inlet with a unique impeller inducer blade handles heavy froth and higher viscosity dense slurries with ease. The horizontal froth pumps has proven valuable for very dense slurries where viscosity starts to become a pumping issue for the standard slurry pumps.

Design Features

Heavy duty construction with through-bolt design provides ease of maintenance and less down time. Ductile iron fully lined casing provides durability, strength and long service life. Large diameter, slow turning, high efficiency impellers maximize wear life and lower TOC. Large, open internal passages reduce internal velocities maximizing wear life resulting in lower operating costs. Unique impeller design for most difficult froth applications. Thick elastomer or metal bolt-in liners provide superior corrosion resistance plus offer ease of liner change-out and inter mixability to reduce over all maintenance costs and maximize wear life. Minimal shaft/impeller overhang reduces shaft deflection and increases packing life. Cartridge-style bearing assembly allows for maintenance in a clean environment without removal of the pump, resulting in reliable operation and prolonged bearing life. Standard TH can be converted by replacing cover plate, throat bush and impeller. Full flush, low flow or dry running centrifugal seals minimize water usage and operating costs.

AHF Froth Pump Applications

The mining industry is a primary example where pumping operations can be plagued by froth and high viscosity problems. In the liberation of minerals from ore, the minerals are often floated through the use of strong flotation agents. Tough bubbles carry the copper, molybdenum or iron tails to be recovered and further processed. These tough bubbles create havoc with many slurry pumps, often leading to the selection of overly large and inefficient pumps. horizontal froth pumps are small and efficient. The inducer impeller and oversized inlet very effectively enable the froth or viscous slurries to get into the impeller allowing the pump to transport it to the next destination. Low power costs, reliable operation, minimal surging, and feed tank overflow make horizontal froth pumps user friendly.
