From severe corrosion to full restoration.
This BB1 pump arrived at our workshop with extensive corrosion affecting critical casing fits, stuffing box areas, and the rotor assembly.
Instead of replacing the complete pump, our team restored the equipment through a combination of precision machining, engineered inserts, rotor refurbishment, and complete reassembly.
The repair included:
★ Restoration of casing ring fits at DE/NDE using engineered inserts and final machining
★ Restoration of stuffing box fits at DE/NDE
★ Refurbishment and rebuilding of the rotor assembly
★ Final assembly of the complete pump for return to service
The before-and-after condition shows how severely deteriorated rotating equipment can often be recovered when the repair is approached from an engineering perspective rather than simply as a parts replacement exercise.
For aging, obsolete, or difficult-to-replace pumps, this type of restoration can significantly extend equipment life and reduce the need for complete replacement.
"Repair. Re-engineer. Restore. Extend equipment life."
