Rotary and Static Equipment Repair Services

Saudi Hydrodynamics Co. Ltd. (Saudi Hydro) provides specialized rotary and static equipment repair services to support the maintenance and reliability of critical industrial assets used in the oil & gas, petrochemical, power, and marine sectors. Our machine shop in Jubail is equipped to recondition and restore equipment components to original OEM specifications, ensuring extended service life and dependable performance.

Shaft and Rotor Reconditioning

We perform complete repair, buildup, and re-machining of shafts, rotors, and couplings damaged due to wear, corrosion, or operational stress. Using precision lathes and VTLs, our technicians restore proper concentricity, straightness, and balance. We employ metal spraying, welding buildup, and precision grinding techniques to recover original dimensions with tight tolerance control.
Applications: motor shafts, turbine rotors, pump shafts, gearbox couplings, and fan rotors.

Pump Casing and Housing Reboring

Our workshop performs precision reboring, keyway cutting, and facing of pump, compressor, and gearbox casings. Misaligned or oval bores are re-machined to correct tolerances, ensuring proper bearing alignment and sealing performance. Each casing is inspected dimensionally before and after machining, following API and OEM standards.

Impeller, Rotor, and Component Restoration

We recondition impellers, sleeves, and rotating elements through machining, polishing, and dynamic balancing. This process restores smooth operation, reduces vibration, and improves overall mechanical efficiency. We also carry out vane buildup, hub bore restoration, and face machining for both metallic and alloy components.

Valve Body and Cover Machining

Saudi Hydro offers machining, refacing, and lapping of valve bodies and covers to restore sealing surfaces and proper fit-up. Our workshop supports gate, globe, check, and control valve components of varying sizes.

Balancing and Run-Out Correction

Dynamic and static balancing is carried out on rotors, fans, and impellers to reduce vibration and prevent bearing damage. All components are verified for concentricity, alignment, and run-out, supported by detailed inspection reports.

Benefits to Clients

• Extended equipment life through accurate re-machining and alignment
• Reduced replacement costs with reconditioning instead of new fabrication
• Improved reliability and reduced vibration levels
• Rapid turnaround during shutdown or emergency maintenance

Every repair is completed under strict quality assurance and dimensional verification, with traceable documentation aligned with Saudi Aramco and SABIC QA/QC procedures.
