Shimadzu Rotor Coating — an OEM option part for original-parts repair of TMP-2203 series molecular pumps — is a factory-specified surface restoration treatment applied to the high-speed rotor of Shimadzu TMP family pumps. It restores the rotor’s original surface finish, mechanical endurance and vacuum compatibility after wear or mechanical service.
Key compatibility: SHIMADZU TMP-2003 through TMP-3603 series (including TMP-2203 family). For ordering and non-standard maintenance options, please refer to Shimadzu molecular pump non-standard maintenance parts.
- Primary function: restore rotor surface for low outgassing, low friction, and consistent aerodynamic performance at high rotational speeds.
- Typical coating characteristics: proprietary low-outgassing ceramic-metal composite (micron-range thickness, typically 1–5 µm), engineered for high hardness, chemical resistance and excellent adhesion to original rotor substrate.
- Benefits: maintains pumping speed and ultimate vacuum, reduces particulate generation and wear, extends service life of the rotor and bearings, minimizes rework compared with rotor replacement.
The coating is manufactured and applied under controlled OEM procedures to ensure balance tolerance and surface uniformity compatible with TMP rotors. For spare-parts lists and specific repair options, consult Original parts repair for TMP-2203.
(for layout only)
Typical inspection and replacement indicators:
- Visible erosion, scratches, or surface pitting on the rotor blade edges or surfaces.
- Increased vibration or noise after balancing and bearing checks.
- Degraded vacuum performance or increased base pressure despite normal maintenance.
Recommended service & installation notes:
- Installation and coating replacement should be performed by qualified service technicians experienced with molecular pumps.
- After coating application, the rotor must be rebalanced to OEM tolerances and inspected for runout before final assembly.
- Use clean-room procedures for assembly; perform a controlled bake-out per Shimadzu repair instructions to remove adventitious adsorbates.
Ordering information:
- Provide pump model and serial number (e.g., TMP-2203, TMP-2403, TMP-3603) when requesting a rotor coating service or replacement rotor.
- OEM re-coating is offered as a service or as an option part to be returned for repair. Contact sales with application details — for example see Shimadzu Rotor Coating Option Parts.
Packaging & warranty:
- Coated rotors are delivered protected in anti-static, low-contamination packaging and shipped with handling instructions.
- Limited warranty applies to coating adhesion and workmanship when installed per OEM procedures; warranty terms available on request.
If you require photos, dimensional checks, or a quotation for rotor re-coating or OEM replacement, please provide the pump model and serial number so we can prepare an accurate repair quote and lead time.
