Heavy Duty Centrifugal Coal Mine Slurry Pump

Heavy duty centrifugal coal mine slurry pump

Design and Products                                                                                

Be adapt to covey heavy abrasion,high concentration dreg, NH slurry pump's body is used double-deck structure,in other words, being made of inside lining and outside shell. 

1, Bearing assembly – a large diameter shaft with short overhang minimizes deflection and contributes to long 

    bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.

2, Liners – easily replaceable liners are bolted, not glued, to the casing for positive attachment and east of

    maintenance. Hard metal liners are completely interchangeable with pressure molded elastomer. Elastomer seal

    rings back all liner joints.

3, Casing – Casing halves of cast or ductile iron with external reinforcing ribs provide high operating pressure 

    capabilities and an extra measure of safety.

4, Impeller – front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Hard

    metal and molded elastomer impellers are completely interchangeable. Cast in impeller threads require no inserts

    or nuts. High efficiency and high head designs are also available.

5, Throatbush – wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive

    accurate alignment during assembly and simple removal.

6, One-piece frame – a very robust one-piece frame cradles the cartridge type bearing and shaft assembly. An

    external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller

    clearance.

There are three types of shaft seal for choose, expeller seal, packing seal and mechanical seal.

A wide variety of impellers and shaft seals provide a perfect fit for a wide range of applications. The NH slurry pump provides excellent wear life while maintaining efficiency during the wear cycle providing the best total operating cost. The NH slurry pump provides a complete selection for most all duties in the mill. From cyclone feed to regrind, flotation and tailings, the NH slurry pump is the best choice.
