Froth Pumps
Heavy-Duty Horizontal Froth Pumps for High Air-Entrained Slurries
SMI’s AHF/MF/LF Horizontal Froth Pumps are specifically engineered to handle frothy, viscous and high air-content slurries commonly encountered in flotation circuits and mineral processing applications. Their robust heavy-duty construction, combined with specialised hydraulic design, delivers reliable performance while reducing maintenance and operating costs.
Featuring large-diameter impellers, oversized internal passages and modular components, the AHF/MF/LF range provides exceptional wear resistance and dependable operation in demanding industrial environments.
Key Features
- Heavy-Duty Through-Bolt Construction
- Large Diameter, High-Efficiency Impellers
- Oversized Internal Flow Passages for Reduced Wear
Advantages of the AHF/MF/LF Horizontal Froth Pump
Purpose-built for handling froth and gas-rich slurries, the AHF/MF/LF Series combines robust construction with efficient hydraulic performance to maximise uptime and minimise operating costs.
Specialised Large Inlet Impeller
The uniquely designed large-diameter impeller inlet efficiently handles viscous slurries, froth and high-solid concentrations while reducing the risk of air blockages. This improves slurry flow and maintains consistent pumping performance.
Exceptional Wear Resistance
Manufactured using premium high chrome alloy or wear-resistant elastomer components, the wet-end parts are built to withstand highly abrasive operating conditions, delivering extended service life and reduced maintenance requirements.
Optimised Hydraulic Performance
Large internal flow passages reduce slurry velocity and minimise internal turbulence, lowering wear rates while improving overall pumping efficiency.
Efficient Low-Speed Operation
High-efficiency impellers are designed to maintain excellent hydraulic performance at lower operating speeds, reducing energy consumption while extending component life.
Heavy-Duty Pump Construction
A reinforced pump casing provides exceptional structural strength, allowing the pump to perform reliably in demanding mining, mineral processing and industrial environments.
Modular Bearing Assembly
The modular bearing arrangement simplifies maintenance and replacement, reducing downtime while improving equipment availability and serviceability.
Easy Maintenance
Replaceable high chrome or rubber liners allow wear components to be replaced quickly without replacing the entire casing.
The accessible bearing assembly enables servicing and component replacement without complete pump disassembly, significantly reducing maintenance time.
Shaft Sealing Options
The AHF/MF/LF Horizontal Froth Pump can be configured with the sealing solution best suited to your application.
Expeller Seal
Provides an effective sealing solution with minimal leakage and reduced dependence on external sealing water under suitable operating conditions.
Gland Seal
A robust and proven sealing option for demanding slurry applications requiring reliable performance.
