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.
