1. Installation Orientation & Structure

AHF Horizontal Froth Pump

• Horizontal mounting with a base-mounted design

• Uses heavy-duty bearing assembly and through-bolt construction

• Double-shell (casing + liner) structure similar to AH slurry pumps

• Suitable for ground-level installation

• Impeller type: Large-diameter, slow-speed, typically open design optimized for froth

AF Vertical Froth Pump

• Vertical cantilever design with no submerged bearings

• The pump is installed directly in the sump or flotation cell

• Semi-open type impeller (IMPELLER – 5 VOG for your model) designed for foam breaking

• No shaft seal required, reducing maintenance

2. Froth Handling Capability

AHF Horizontal Pump

• Designed with large, open passages

• Enhanced ability to separate air from froth before entering the impeller

• Stable flow and higher efficiency in foam-rich slurry pipelines

AF Vertical Pump

• Gravity-assisted froth feeding

• The vertical design allows froth to naturally drop into the pump inlet

• Better handling of extremely high froth concentrations in flotation cells

3. Application Differences

AHF Horizontal Froth Pump

Best for:

• Long-distance transport of frothy slurry

• Flotation concentrate delivery

• Pipeline transportation where installation space allows

• Copper/moly/iron ore flotation plants

• Applications requiring high head and higher flow rates

AF Vertical Froth Pump

Best for:

• Direct installation in sump/foam tank

• Handling froth directly from flotation cells

• Situations where no sealing system is preferred

• Areas with limited floor space

• Medium-head applications with continuous foam overflow

4. Maintenance & Operation

AHF Horizontal Froth Pump

• Easier access to pump components

• Higher maintenance convenience

• Requires shaft seal (packing or expeller seal)

AF Vertical Froth Pump

• No need for shaft seals

• No submerged bearings, reducing failure risks

• Lower maintenance cost

• More suitable for unstable foam conditions

5. Performance Characteristics

AHF Horizontal Pump

• Higher efficiency and longer wear life

• More stable pressure output

• Compatible with Warman® AHF design (CNSME Pump full interchangeability)

AF Vertical Pump

• Strong adaptability to foam surges

• Lower power consumption

• Handles coarse particles and high-density froth

• CNSME Pump AF vertical froth pump improves foam-breaking efficiency
