Overhaul
TOP > Service Solutions > Overhaul
The overhaul division transports the customer’s pump back to our service facility, disassembles the pump, and thoroughly inspects every component in detail.
By repairing parts as necessary and replacing parts according to the customer’s specifications, we can significantly improve the pump’s efficiency and performance.
Regular Inspection and Maintenance Process

- Inspection
-
PT Inspection
Check the condition of the sliding surface of the balance disk, seat, thrust collar and/or bearing shell and determine whether it can be reused or a replacement is required.
-
Clearance Inspection

-
Re-lapping
Re-lapping of the mechanical seal faces is conducted when necessary.
- Balancing
-
Dynamic Balancing
Adjust the unbalanced rotor assembly and restore the rotor to its original condition.
- Testing
-
Performance Test
After all maintenance completed, we conduct a performance test to confirm that the efficiency is improved.
