The challenge

Mining operations are particularly challenging for all kinds of equipment and Sulzer provides a pump repair service that includes slurry pumps from other OEMs.

  • The original stainless steel guards are manually TIG welded and painted
  • Making new parts took a skilled fabricator 4-6 hours
  • OEM lead times could be 6-8 weeks
  • Downtime for the mining operation needed to be minimized

We are always looking for ways to improve our service to pump operators, and this was a solution that increased the speed of repair and offered excellent performance. The original parts are often missing when these pumps come in for repair and we wanted to minimize the turnaround time using an alternative, high-quality solution.

The first prototype was checked for fit and finish

The solution

Sulzer created a 3D scan of the original components and developed a set of prototype parts to check for fit and finish. The design was optimized for additive manufacturing and put into production.

The new components were manufactured using Acrylonitrile Styrene Acrylate (ASA) material:

  • Parts manufactured in yellow – no painting required
  • Superior corrosion resistance to stainless steel
  • Impact resistance and toughness suitable for the application
  • Improved fit and consistency compared to hand-made OEM parts
  • Reduced lead time for parts

Customer benefit

The main benefit for these additive manufactured guards is reduced lead time allowing a “faster and better” service to the customer. The AM process also allows optimization of the design for improved performance, fit and finish than would be possible with handmade stainless steel parts. The benefits achieved by the first customer will be appreciated by all others that are operating this model of pump.
