    The ICS Mill Master pump was born from Warman® SP/SPR® pump which is the world’s standard for heavy duties. With wide variety of impellers and shaft seals provide a perfect fit for a wide range of applications. Our Heavy Duty Mill Master SP pump provides exceptional wear life while maintaining efficiency during the wear cycle providing the best total operating cost. For the full spectrum of applications, the ICS Mill Master pump is the best choice.

    • Bearing assembly – a large diameter shaft with short overhang minimizes deflection and contributes to long bearing life.
    • Liners-easily replaceable liners are bolted, not glued, to the casing for positive attachment and ease of maintenance. Hard metal liners are completely interchangeable with pressure moulded elastomer.
    • Elastomer seal rings back all liner joints.
    • Impeller–front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Metal and moulded elastomer impellers are completely interchangeable.
    • Cast in impeller threads require no inserts or nuts. High efficiency and high head designs are also available.
    • Throatbush–wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal.
    • An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance
