    Product Introduction

    The SF Froth Pump is a vertical centrifugal slurry pump specially designed for handling air-entrained frothy slurry generated during flotation processes.

    During mineral flotation, large amounts of air bubbles are introduced into the slurry, creating low-density froth with high air content. Conventional slurry pumps may experience unstable operation, reduced efficiency and air blockage when transporting this type of slurry.

    The SF series froth pump adopts a specially designed vertical structure to improve froth transportation performance. It can continuously handle low-density, high-air-content slurry and maintain stable operation even under unstable feed conditions.

    The pump is widely used in mining, metallurgy, coal preparation, phosphate processing and other mineral separation industries.

    Why Use SF Froth Pump in Flotation Applications?

    Flotation circuits generate slurry containing a large amount of trapped air. This makes transportation more challenging than normal slurry handling.

    Compared with standard slurry pumps, SF froth pumps provide:

    • Better air-entrained slurry handling capability
    • Reduced risk of air locking
    • Stable operation under fluctuating feed conditions
    • Improved flotation circuit reliability
    • Lower maintenance requirements

    The vertical design allows the pump to operate efficiently in applications where slurry flow conditions are unstable.

    Structure & Design Features

    The SF froth pump adopts a simple and efficient vertical centrifugal structure.

    Main Design Features:

    Vertical Cantilever Structure

    The vertical arrangement reduces installation requirements and allows reliable operation without additional shaft sealing systems.

    Tangential Inlet Design

    The tangential inlet helps reduce slurry turbulence and improves the transportation of frothy slurry.

    Overflow Return System

    The overflow system helps maintain stable operation by returning excess froth and reducing air accumulation.

    Wear Resistant Wet-End Components

    The impeller and wet-end parts are manufactured from high wear-resistant materials, including high chrome alloy, to withstand abrasive slurry conditions.

    Flexible Drive System

    The pump supports direct drive or pulley drive systems, allowing speed adjustment according to process requirements.
