Key Benefits

  • Pumps large and abrasive solids
  • Pulls a higher vacuum
  • Adjustable while in operation
  • Reduces cost per ton
  • Longer service life

Treat the cause of slurry pump inefficiency with our gravelMAX™ pump

Many slurry pump applications in hard rock mining, coal and dredging require the ability to pump large solids. Why put up with a pump that is not built for your needs?

Easily adjustable wear ring while pump is in operation

Our wear ring maintains the suction side clearance in your pump and eliminates recirculation. Without the inefficiencies of conventional pump designs, our gravelMAX processes more slurry and pulls a higher vacuum. It processes a higher percent solids and higher density solids than any other pump in its class.

 

You can safely adjust the wear ring in minutes during operation to keep a constant pump flow and pressure. This eliminates the conventional process of increasing the pump speed to maintain the flow as the impeller or liners wear.

Industries and applications

  • Aggregates (sand plants, cyclone feed, tailings)
  • Coal (heavy media cyclone feed)
  • Hard rock mining
  • Dredging
  • Froth
  • Heavy-duty abrasive slurries
  • Any application requiring large solids passing

Higher quality pumping at a lower cost per ton—what’s not to love?

Passing large solids

It is no accident that gravelMAX slurry pumps are better at handling large solids—it’s in their design. A large clearance between the impeller and suction side prevents solids from grinding when they enter the pump. And a wide diameter impeller and increased cutwater clearance lets the pump easily pass them out the other side.

 

When your pump smoothly processes slurry without grinding, it has higher throughput, uses less energy, wears more slowly, runs longer between shutdowns and costs you less per ton pumped.

Lowered costs and energy consumption

It should be no surprise that a pump which operates more efficiently also operates less expensively. In established gravelMAX installations, parts wear evenly and overall wear life has improved by 50% to 100% compared to conventional slurry pumps. Longer wear life means less downtime and lower maintenance costs.

 

Our customers have also noted a 10% to 20% or greater reduction in power consumption, which saves them money and allows additional pumping capacity without getting a larger motor.

Designed for excellence

The gravelMAX slurry pump has a unique patented design developed for severe abrasive slurries in mining and dredging operations.

Power frame

  • Heavy-duty cast pedestal

  • External bearing assembly adjustment

  • Wide bearing centres

  • Heavy-duty shaft and bearings

 

 

Reverse-taper roller bearings

 

  • Larger effective load span to improve B-10 life
