KREBS millMAX™ Pumps

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 clearances at expelling vanes prevents large solids from being crushed.

Tight clearances at the wear ring pre-vents suction-side recirculation.

Tight clearances at backliner ensures that shaft sealing system works 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 millMAX™ Pump is a new design, hard metal pump and wet end conversion kit, designed exclusively for mill discharge and other abrasive slurries. The Krebs millMAX™ Pump adapts to a variety of power frames without disturbing the foundation or bearing frame assemblies.

The millMAX™ design can be applied to an existing pump through a wet end conversion kit, including impeller, casing, backliner, and gland seal.

The millMAX™ conversion 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.
