MDX

Summary

Product identification

The GIW® MDX - Mill Duty Extra Heavy Pumps are designed for severe mill duty applications.

Operating limits

• Discharge: 150 to 850 mm
• Flow rates: up to 16,500 m³/h (up to 72,650 gpm)
• Total head: up to 51 m (up to 170 ft)
• Pressure rating: up to 14.2 bar (up to 206 psi)

Feed water

The pumps are designed for aggressive slurries encountered in mill circuits. GIW Minerals offers a wide range of white iron materials specifically designed to resist the abrasive nature of aggressive slurries.

Mechanical / hydraulic

Applications

• SAG, Ball and Rod Mill Discharge
• Cyclone and Screen Feed

Design Features

• Lower Specific Speed Design: A large diameter impeller results in slower pump rotational speed than competing designs, leading to extended wear life. The lower specific speed design also allows the pump to better meet the variable flow conditions encountered in mill circuits.
• Longer Wearing Materials: Wide range of white iron materials designed specifically to resist the abrasive nature of aggressive slurries. Combined with thicker cross sections, this translates into long and reliable pump service life.
• Deep Base Circle: Minimizes aggressive particle impingement and encourages “sliding” wear.
• Slurry Diverter: Dramatically increases suction liner life by reducing particle recirculation between the impeller and liner.
• Oversize Shrouds: Larger shrouds and extended vanes work in conjunction with the slurry diverter to provide additional clearing action, further reducing recirculation and grinding wear between the impeller and suction liner.
• Adjustable Suction Liner: Allows nose gap adjustment on the fly, which in turn reduces downtime and extends the wear life.
• Patented Inlet 5 Vane Impeller: Designed to efficiently transport aggressive slurries while maximizing pump performance and wear life, and minimizing vibration.
