Shimadzu G Rotor Coating Original Parts Repair for TMP 2203LMTG Molecular Pump

Materials and surface treatment
The coating is applied to precision-machined rotor geometry using vacuum-compatible processes. Materials are selected to minimize particulate generation and hydrocarbon contamination. Typical treatments include adhesion primer, wear-resistant outer layer and final low-outgassing finish. All parts are processed in a controlled environment and are cleaned and packaged to prevent recontamination.

Quality & testing
Each coated rotor undergoes:

• Dimensional inspection against OEM drawing tolerances
• Dynamic balance testing to specified RPM range
• Surface adhesion and hardness checks
• Cleanroom packaging and vacuum compatibility verification

These steps ensure restored pumps meet original performance specifications after installation and break-in procedures.

Installation & service notes
- Handle rotors with clean, lint-free gloves. Avoid fingerprint contamination on coated surfaces.
- Verify rotor balance and free rotation before final assembly. Follow the pump manufacturer’s torque and assembly sequence for bearings and housing.
- Run a controlled bake-in / conditioning cycle as recommended by the pump service manual to stabilize the coating under operating temperature and vacuum.
- If replacing only the rotor coating, inspect stator, bearings and seals; replace worn bearing components to prevent premature re-wear of the new coating.

Compatibility and part identification
This coating/repair part is specifically tailored for the TMP-2203LMTG configuration but is compatible across the broader SHIMADZU TMP-2003 to TMP-3603 family when correct rotor size and balance specification are confirmed. Provide your pump model, serial number and any original part numbers when ordering to ensure correct match.

Ordering, lead times & packaging
Typical delivery includes:

• Coated rotor unit (single piece) or rotor+repair kit by request
• Certificate of conformity and inspection report
• Cleanroom packaging with protective caps

Lead time depends on stock and coating schedule — request a quote with your pump details for accurate lead times. For spare part options and non-standard maintenance components, see our parts page: Shimadzu molecular pump non-standard maintenance parts.

Why choose an OEM-grade coating repair?
Restoring rotor surfaces with an OEM-grade coating is generally more cost-effective than full rotor replacement and brings back aerodynamic efficiency and vacuum performance. Properly applied coatings help reduce micro-leak sources, decrease recovery time after venting, and extend bearing and seal life when combined with full-service inspection.
