This Froth Pump provides two main structural configurations: horizontal double-casing type and vertical cantilever type. The enlarged tangential suction port cooperates with inducer semi-open impeller to break massive bubbles and discharge entrapped air inside slurry. Wetted components can adopt high-chromium alloy, natural rubber or polyurethane to handle abrasive and slightly corrosive frothy medium.We deliver professional flotation-condition selection calculation, factory performance test report, installation-operation manual and full set export-oriented technical documents. OEM service and full-range interchangeable wear spare-parts are available for mineral-processing plant requirements.

Product Advantages
Powerful Anti-air-locking Froth-handling Capacity
Unique inducer impeller plus oversized tangential inlet disintegrate froth and exhaust trapped air, avoiding air-binding failure common for standard slurry pumps on flotation froth service.
Two-type Structural Alternatives
Horizontal AHF for large-volume continuous froth transportation; vertical AF cantilever without submerged seals, perfectly suited for flotation cell overflow transfer scenarios.
Multiple Wetted-part Material Options
High-chromium alloy, rubber and polyurethane liners optional to match abrasive or mildly corrosive frothy slurry conditions.
Flexible Shaft-seal Solutions
Expeller dynamic seal supports zero sealing-water operation; packing seal and mechanical seal adapt different on-site water-supply resources.
Stable Operation Under Poor-feed Condition
Optimized hydraulic profile maintains stable running even with insufficient incoming froth from flotation cell overflow.
Convenient Maintenance & Complete Spare-parts
Quick-replaceable wear-resistant wetted components; interchangeable spare-parts with short lead-time minimize mine-site production downtime loss.
Product Customization
Structure Customization: Select horizontal AHF or vertical AF cantilever model according to site layout, liquid-level fluctuation and installation space constraints.
Wetted-part Material: Custom high-chromium alloy, natural rubber or polyurethane wetted components based on particle hardness and medium corrosiveness.
Performance Adjustment: Adjust impeller specification, rotating speed and drive mode (V-belt / direct coupling) to satisfy target flow and head. Shaft Seal Configuration: Configure expeller seal, packing seal or mechanical seal subject to on-site sealing-water supply actual situation. OEM & Spare-part Service: Accept customer-branded OEM production; supply impeller, liner, throat bush and other replaceable wear parts per drawings or samples.
FAQ
Q: Why cannot ordinary slurry pumps work reliably for flotation froth conveying?
A: Conventional slurry pumps easily suffer air-locking caused by high air volume inside froth, resulting in flow fluctuation, heavy vibration and even complete loss of delivery capacity.
Q: What working-condition parameters should be submitted for quotation of Froth Pump?
A: Please provide required flow rate, total head, froth volume air content, solid weight concentration, medium abrasion-corrosion property, installation pattern and destination port information.
Q: Can vertical froth pump be directly mounted below flotation-cell overflow outlet?
A: Yes. Vertical AF series without submerged bearing and shaft seal is purpose-built for flotation-trough overflow. Please keep medium immersion depth within allowable technical range.
