KREBS® gravelMAX™ slurry and dredge pump

Optimized design for abrasive slurries with large solids

Our innovative hydraulic design makes the gravelMAX the perfect solution for optimized passing size, efficiency and wear life.

Key Benefit

Efficient pumping of large, abrasive solids – lower cost per ton
Pumps large and abrasive solids expand_more

The wide diameter impeller and increased cutwater clearance allows for the passing of large solids. The wide clearance between the impeller and suction side ensures that solids are not ground up in the pump as they would be with conventional designs.

Adjustable while in operation expand_more
With our millMAX suction-side sealing system, the wear ring, the front clearance is adjustable during operation, and takes only five minutes to perform. Because the wear ring can be adjusted while the pump is in operation, the pump achieves a constant flow and pressure, without the need to speed it up. This extends the life of all wet end parts and reduces power consumption.
Pulls a higher vacuum expand_more
By eliminating the suction-side recirculation that breaks the vacuum at the eye of the impeller on conventional pumps, the wear ring advantage allows the gravelMAX to pump a higher percent solids and higher density solids than any other pump in its class. The ability to pull a higher vacuum makes our gravelMAX ideal for the dredging industry.
Reduces cost per ton expand_more
Lower power requirements, long wear life and less pump downtime all result in lower cost-per-ton pumped.
Longer service life expand_more
The gravelMAX’s increased clearances, wide diameter impeller and suction-side sealing system work together to offer even and predictable wear rates, less downtime, increased throughput and lower electricity consumption.

PRODUCT FEATURES

Patented, proprietary features eliminate common problems
The gravelMAX pump has a unique patented design developed for severe abrasive slurries. It features a proprietary suction-side sealing system and patented online wear clearance adjustment, which minimises the cost-per-ton pumped, compared to conventional hard metal and rubber lined slurry pumps.
 
 

 

The gravelMAX not only eliminates inefficient recirculation but also the grinding of slurry. Our gravelMAX pumps are part of the ONLY pump line in the market that can eliminate both problems effectively. Additional features include:

Adjustable wear ring

  • Allows pumping of higher percent solids and higher-density slurries
  • Reduces suction-side recirculation
  • Maintains hydraulic performance

millMAX™ power frame

  • Heavy-duty cast pedestal
  • External bearing assembly adjustment
  • Wide bearing centres
  • Heavy-duty shaft and bearings

Reverse-taper roller bearings

  • Increase the effective load span to improve B-10 life
  • Pumping action of taper rollers discharges grease to the outside, preventing ingress of slurry and eliminating
    possibility of failure due to over-greasing
