FAF Vertical Froth Pumps

FAF Series Vertical Froth Pumps represent the latest generation of froth handling technology, integrating advanced domestic and international innovations. Engineered to efficiently pump frothy slurries, these pumps utilize an induced vortex principle to de-aerate or partially de-aerate the froth before it enters the pump head, enhancing operational efficiency and reducing air-induced performance losses.

Designed as double-casing vertical pumps with a hopper, FAF models feature replaceable abrasion-resistant high-chrome white-iron or moulded rubber casing liners and impellers, ensuring durability in abrasive or corrosive environments. The hopper-tank, fabricated from steel plate, can be lined with specialized materials based on the medium being pumped, offering versatile adaptability to diverse industrial needs.

Typical Applications of FAF Vertical Froth Pumps

FAF Vertical Froth Pumps excel in industries requiring the transport of frothy, abrasive, or corrosive slurries, including:
Iron, copper, gold, and molybdenum ore dressing plants
Potash fertilizer and mineral processing facilities
Metallurgy, coal chemical, paper, and pulp industries
Flotation processes and other froth-intensive applications
