Keeping Slurry Pumps in Peak Condition—Without the Manufacturer Wait Times

When a slurry pump from a mining client mine arrived at Southern Pumping for an overhaul, we knew exactly what to expect—heavy wear, signs of abrasive duty, and the usual battle scars from pumping tough slurries. But instead of a long, expensive wait for manufacturer servicing, our team stepped up to provide a timely and budget-friendly solution.

The Challenge: Wear and Cavitation

After stripping the pump down, our inspection revealed extensive wear on the wet-end components—impeller, volute liner, and frame plate liner—all showing heavy abrasion. We also noticed localized damage suggesting possible cavitation issues, which, if left unaddressed, could lead to premature failures in the future.

Beyond wear and tear, some modifications had been made to the pump’s gland follower, adding an extra Teflon flinger. Our job wasn’t just to replace worn parts—it was to rebuild the pump to perform at its best for the long haul.

Our Solution: Expert Overhaul and Precision Rebuild

Southern Pumping doesn’t just swap out components; we take a meticulous approach to pump overhauls. Here’s what we did:

• Surface Prep: All pump components were grit-blasted and primed to ensure longevity and proper adhesion of new parts.
• Replacement of Critical Components: The volute liner, impeller, frame plate liner, shaft sleeve, and packing were replaced.
• New Bearings and Seals: Timken bearings, O-rings, and labyrinth seals were installed to restore full operational integrity.
• Precision Engineering: The bearing barrel was rebuilt with tolerances set precisely to manufacturer specifications, ensuring smooth operation.
• Custom Modifications Retained: We replaced the modified Teflon flinger like-for-like, maintaining the customer’s preferred setup while ensuring functionality.
