OUTOTEC GIW SLURRY PUMPS
MDX SERIES
Mill Duty Xtra Heavy pump (MDX), the heart
of the mill circuit, is designed specifically for
the most extreme duty conditions. The pump’s
service cycles can be matched with scheduled
mill outages, increasing the mill’s availability
and productivity. With a long wearing design
and use of high abrasive resistant materials,
these pumps deliver reliable tonnage while
keeping annual operating expenditure to a
minimum.
BENEFITS
• Improved availability by matching
service cycles with mill outages
• Reduced maintenance costs with long
wearing white iron materials
• Maximized suction liner and impeller
wear life to reduce component costs
• Safe and consistent maintenance

OPTIMIZED PRODUCTIVITY FOR GRINDING CIRCUITS
The MDX series of Outotec GIWTM slurry pumps* is optimized for heavy-duty use in the grinding mill circuit of a
concentrator plant. With Outotec’s extensive expertise in comminution processes and global service and support network,
we support you throughout the pump’s life cycle, improving the productivity of your process and operations.
The MDX pumps offer many unique features that improve reliability, performance and productivity of the grinding circuit.
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
MDX slurry pumps offer a wide range of white iron
materials designed specifically to resist the abrasive
nature of aggressive slurries. This, combined with thicker
cross sections, translates into long and reliable pump
service life.
Deep base circle
Minimizes aggressive particle impingement and
encourages sliding wear. Typical abrasive wear drops
dramatically.
Slurry diverter
The latest technology 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
minimize vibration.
Reduce downtime by matching life cycles
Select the MDX pump for your next mill circuit application
to help ensure cost-effective and continuous operations.
The MDX pump maximizes productivity and minimizes
cost by matching operating cycle times with scheduled
mill outages.
