Our Flowserve Rebuild Process

Every Flowserve rebuild follows a documented process — from teardown through load test. No shortcuts, no guesswork.

01

Teardown & Inspection

Complete disassembly with photographic documentation. Every gear, bearing, shaft, seal, and housing is inspected and measured against OEM specifications.

02

Failure Analysis

We identify the root cause — not just the symptom. Overloading, misalignment, lubrication failure, contamination, and fatigue are all documented before rebuild begins.

03

Precision Machining

Worn bores are re-machined to OEM tolerances. Shafts are repaired or replaced. Housings are cleaned, inspected for cracks, and restored to spec.

04

Component Replacement

Worn or damaged components are replaced — gears cut in-house to AGMA standards, bearings and seals replaced with OEM-equivalent or upgraded parts.

05

Assembly

Rebuilt units are assembled to OEM torque specs with fresh lubricant and new seals throughout.

06

Load Testing

Every major rebuild is load-tested on our 500 HP test stand. Vibration, temperature, and flow are verified before shipment.
