Overview
Krebs millMAX™ severe-duty slurry pumps have a unique patented design developed exclusively for grinding mill discharge duties and other abrasive slurries.
FLSmidth Krebs offers wet end conversions or complete pump assemblies to meet customer desires and demands.
The key advantage of the Krebs Metal Slurry Pumps is the 10% to 30% lower power, long even wear life and less pump downtime, which results in lower cost-per-ton pumped, along with better cyclone separation.
Applications
Mill discharge, crusher slurry, sand and aggregate or any coarse solids or other severe, abrasive slurries especially in the copper, gold, lead-zinc, coal, or phosphate plants. The most dramatic savings will be in these applications, though savings will also be realized on fine solids, like iron ore or kaolin.
Benefits
The millMAX™ Pump features a patented on-line wear clearance adjustment.
Minimizes cost per ton pumped compared to conventional hard metal and rubber lined pumps through:
- Increased Wear Life
- Lower Power Consumption
- On-line Wear Clearance Adjustment
- Increased Mill Throughput
- More Consistent Hydrocyclone Separation
- Less Downtime
Features
Casing- designed for minimum slurry turbulence and even wear. Includes (14x12 and smaller) integral wear ring, carrier, and adjustment screws for on-line adjustment and elimination of suction side recirculation.
Wear Ring - 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 - designed for high slurry efficiency and hydraulic performance. Machined surface at the eye for wear ring adjustment and high expelling vanes.
Backliner - designed for close clearance at the back (14x12 and smaller), or SUCTION LINER with integral wear ring (16x14 and larger). 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.
Flanges - loose intake and discharge flanges drilled to suit various pipe requirements.
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.
High Radial Vanes
- Clears large solids
- Prevents solids from being crushed
- Reduces casing slurry pressure at the eye of the impeller
External Wear Adjustment Screw
- 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 clearance at the impeller
- Adjusted during operation
- Reduces suction side recirculation
- Maintains hydraulic performance
