Overview

Horizontal froth pumps are specialized centrifugal pumps designed to handle aerated slurries, frothy mixtures, and viscous fluids in mineral processing (especially flotation circuits). They feature unique designs to prevent air locking and maintain steady flow.

Key Features

✔ Froth-Handling Design

Large volute & impeller to handle air bubbles (up to 30% air content)

Anti-vortex impeller prevents air blockage

✔ Robust Construction

High-chrome alloys (Cr27, Cr30) or rubber-lined for wear/corrosion resistance

Reinforced shafts for high torque

✔ Specialized Sealing

Expeller + gland packing (standard)

Double mechanical seals (for hazardous fluids)

✔ Efficient Air Management

Deaeration ports to vent excess air

Stable performance in flotation cells, tailings, and CIP circuits

Typical Applications

Flotation Cells (Copper, Gold, Coal processing)

Leach & CIP Circuits

Tailings Froth Handling

Scavenger & Rougher Feed
