Increase Power & Reduce Cost in your mining enterprise
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.
The gravelMAX™ Pump has a unique patented design developed for severe abrasive slurries.
The gravelMAX™ 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:
-
Pump higher percent solids
-
Maintenance of suction vacuum
-
Increase deposit life by digging deeper
-
Reduce power costs
-
Reduce the cost per ton
-
Adjust pump while running
-
Longer wear life of parts
Features
Casing
The gravelMAX Casing is designed for minimum slurry turbulence and even wear. Includes integral wear ring, carrier, and adjustment screws for on-line adjustment and elimination of suction side recirculation.
Wear Ring
The adjustable wear ring assembly to permit closing of suction side impeller clearance during operation. This reduces slurry recirculation and lowers pressure at the suction area, thereby maintaining flow and reducing wear.
Impeller
The imperller is designed for high slurry efficiency and hydraulic performance. Machined surface at the eye for wear ring adjustment and high expelling vanes.
Backliner
(Dependent on pump size), these are designed for close clearance at the back. Matching full impeller diameter and profile for close operating clearance.
Wear Parts
Designed hydraulically to wear evenly. Constructed of high chrome at 680/720 Brinell hardness.
Power Frame
Heavy duty cast iron pedestal with external bearing assembly adjustment mechanism. Drilled for overhead motor mounting assembly.
Bearing Assembly
Heavy duty shaft and indirect fitted taper roller bearings rated at 100,000 hrs B-10 life minimum. Bearing arrangement designed to prevent over greasing and ingress of slurry.
