The Heart of the DesignThe patented on-line suction side wear
clearance adjustment permits the initial
clearances to be maintained throughout
the life of the pump. This extends the life of
the impeller and suction wear faces to near,
or equal that of, the casing for a one time
maintenance rebuild.
The reduction of solids grinding between
the impeller and suction side reduces power
consumption and wear. The millMAX
Hybrid Suction Sealing System maintains
constant flow and pressure, without
increasing speed or the danger of motor
overload.
KREBS millMAX TECHNOLOGYThe millMAX Pump has a unique
patented design developed exclusively for
mill discharge duties and adapted for other
severe abrasive slurries.
The same wet end components can be
offered as a conversion kit to existing
pumps, without the need to disturb the
foundation or existing bearing frame
assembly.
The millMAX Pump features a patented
on-line wear clearance adjustment, which
minimizes the cost per ton pumped
compared to conventional hard metal and
rubber lined slurry pumps through:
Increased wear life
Even wear life of all wet end parts
Less down time
Lower power consumption
Increased mill throughput
More consistent cyclone separation
Improved gland seal performance
Low-cost no risk wet end
replacement
Wide clearancesat expelling vanesprevents largesolids from beingcrushed.
Tight clearances atthe wear ring pre-vents suction-siderecirculation.
Tight clearances atbackliner ensures thatshaft sealing systemworks well.

Krebs millMAX Pumps treat the cause of
pump wear and loss of efficiency, whereas
competitive pumps treat the symptoms
through materials or predictive uneven wear
rates.
In most established millMAX installations,
wear life of parts has been even and in
the majority, overall wear life has generally
improved by 50% to 100%. This increase
in wear life is achieved together with a
reduction in power, generally in the 10% to
20% or lower range.
The reduction in power can then be taken
as a cost savings, or through additional
pumping capacity with the same installed
motor.
With the millMAX Hybrid Suction Sealing
System, the front clearance is adjusted
while the pump is running, and takes only
five minutes to perform. This clearance
is adjusted normally six to eight times
throughout the life of the wet end parts.

The Krebs millMAXPump is a new design,
hard metal pump and wet end conversion
kit, designed exclusively for mill discharge
and other abrasive slurries. The Krebs
millMAXPump adapts to a variety of power
frames without disturbing the foundation or
bearing frame assemblies.
The millMAXdesign can be applied to an
existing pump through a wet end conversion
kit, including impeller, casing, backliner, and
gland seal.
The millMAXconversion kit is supplied
with an adapter ring, seals, and all hardware
to adapt to a variety of power frames. This
achieves the same results as a complete
pump on a maintenance budget.

SPECIFICATIONS
CASING- designed for minimum slurry turbulence and evenwear. Includes (14x12 and smaller) integral wear ring, carrier,and adjustment screws for on-line adjustment and elimination ofsuction side recirculation.
WEAR RING- adjustable wear ring assembly to permit closingof suction side impeller clearance during operation. This reducesslurry recirculation and lowers pressure at the suction area,thereby maintaining ow and reducing wear.
IMPELLER- designed for high slurry efficiency and hydraulicperformance. Machined surface at the eye for wear ring adjust -ment and high expelling vanes.
BACKLINER- designed for close clearance at the back (14x12and smaller), or SUCTION LINERwith integral wear ring(16x14 and larger). Matching full impeller diameter and prolefor close operating clearance.
High Radial Vanes Clears large solids. Prevents solids from being crushed. Reduces casing slurry pressure at the eye
of the impeller.
External Wear AdjustmentScrew Four screws for on-line wear
clearance adjustment. Adjusted while the pump is
operating. Adjusted six to eight times
during the life of the pump.
Adjustable Wear Ring Wear ring takes up clear-
ance at the impeller. Adjusted during operation. Reduces suction side recir-
culation. Maintains hydraulic per-
formance.
WEAR PARTS- designed hydraulically to wear evenly. Construct-ed of high chrome at 680/720 Brinell hardness.
POWER FRAME- heavy duty cast iron pedestal with externalbearing assembly adjustment mechanism. Drilled for overheadmotor mounting assembly.
FLANGES- loose intake and discharge anges drilled to suit vari -ous pipe requirements.
BEARING ASSEMBLY- heavy duty shaft and indirect fittedtaper roller bearings rated at 100,000 hrs B-10 life minimum.Bearing arrangement designed to prevent over greasing and ingressof slurry.
Slurry pumps are Krebs millMAXdesign and include the following:
No adjustment of impeller oncethe pump is installed.
Narrow ClearanceReduces pressure at gland toassist centrifugal dry gland seal orreduce gland water pressure.
Wide Clearance Dramatic reduction in crushing of
solids. Increased wear life. Reduced power consumption.
