FAHF Froth Pumps

FAHF Series Horizontal Froth Pumps are heavy-duty, horizontal centrifugal pumps specifically designed to tackle thick froth slurries and high-viscosity media that pose challenges for standard slurry pumps. Engineered with a unique impeller-driven blade and an oversized inlet, these pumps efficiently handle dense, air-entrained slurries, making them ideal for flotation processes, mineral processing, and other industries where foam and viscosity hinder pump performance.

Typical Applications of FAHF Froth Pumps

FAHF pumps excel in industries where frothy, high-viscosity slurries are prevalent:

Mineral Processing: Copper, iron ore, gold, molybdenum, and potash flotation plants, where strong flotation agents create persistent foam that standard pumps struggle to handle.
Chemical Processing: Applications involving frothy slurries in chemical synthesis or separation processes.
Pulp & Paper Industry: Handling viscous pulps and frothy by-products.
Non-Ferrous Metal Beneficiation: Efficiently transporting froth-laden slurries during ore concentration.

Key Design Features of FAHF Froth Pumps

Robust Construction for Durability:

Through-bolt design ensures easy maintenance and minimizes downtime, enhancing operational efficiency.
Fully lined ductile iron casing offers exceptional strength, wear resistance, and long service life.
Wear-Resistant Materials: High chrome alloy, natural rubber, or polyurethane to suit different slurry abrasiveness and chemical compatibility needs.

Optimized Fluid Handling:

Large-diameter, low-speed impellers deliver high efficiency while extending component life.
Generous internal passages reduce flow velocities, minimizing wear and lowering operating costs.
Unique impeller design with an inducer blade effectively breaks down foam and prevents air-locking, even in the most stubborn frothy applications.

Enhanced Mechanical Design:

Minimal shaft/impeller overhang reduces deflection, extending seal life and ensuring stable operation.
Cartridge bearing assemblies allow maintenance in a clean environment without disassembling the pump, promoting reliable performance and prolonged bearing life.
Drive Types & Installations: Multiple configurations (e.g., belt drive, direct drive) and mounting options to adapt to site-specific requirements.
