Product: Shimadzu Rotor Disk (Part No. 3003) — original repair part for TMP-2003 ~ TMP-3603 series molecular (turbomolecular) pumps.
This replacement rotor disk is an OEM-quality component manufactured to the original Shimadzu specifications for the TMP-2003 through TMP-3603 series. It is intended for use during repair and refurbishment of turbomolecular pumps where the rotating assembly has experienced wear, surface damage, or balancing degradation. Restoring the rotor disk to factory condition is essential to recover pumping speed, reduce vibration, and extend service life of the pump.
Main features
- Direct replacement for Shimadzu TMP-2003 ~ TMP-3603 series (Rotor Disk model 3003).
- Manufactured from high-strength, vacuum-compatible alloy with precision machining and surface treatment to resist wear and maintain geometry at high rotational speeds.
- Dynamically balanced to tight tolerances to minimize vibration and bearing loads at rated RPM.
- Surface finishes and concentricity controlled to ensure optimal gas flow and molecular pumping efficiency.
- Supplied with identification marking and quality inspection records (where applicable) for traceability.
Typical benefits
- Restores original pump performance (pumping speed and compression ratios) after rotor wear or damage.
- Reduces bearing wear and operating vibration through precision balance and concentricity control.
- Helps avoid costly full rotor replacements by enabling targeted repair of the rotating assembly.
- OEM-fit component simplifies installation and avoids compatibility issues common with lower-quality aftermarket parts.
Compatibility
- Designed for SHIMADZU TMP-2003 through TMP-3603 turbomolecular pump models.
- Intended as an original parts repair item for service centers and field technicians performing rotor/impeller replacement.
Installation notes
- Installation should be performed by trained service personnel with appropriate cleanroom or clean-bench procedures to prevent particle contamination.
- Inspect mating surfaces, bearings, and shaft runout before assembly. Replace bearings or seals if wear is detected.
- Follow manufacturer torque specifications for fasteners and perform dynamic balancing after assembly if required by the service procedure.
- Perform a vacuum leak check and vibration/runout test at low speed before returning the pump to full operating RPM.
Inspection & maintenance
- Regularly inspect the rotor disk surface for nicks, grooves, or material loss that can unbalance the rotor.
- Monitor vibration signatures and bearing temperatures; sudden changes often indicate rotor damage or imbalance.
- Maintain cleanliness during handling. Use gloves and soft, lint-free tools to avoid scratches or contamination.

Quality assurance & warranty
Each rotor disk is inspected for dimensional accuracy and dynamic balance prior to shipment. Parts are shipped in protective packaging to prevent handling damage. Confirm warranty and return policy with your supplier; for certified parts and after-sales service information visit Taixing Pump Catalog.
Safety & handling
- Handle with care — rotor disks are precision-machined parts sensitive to surface damage and contamination.
- Store in a clean, dry environment away from corrosive atmospheres.
- Use appropriate personal protective equipment when installing or removing rotating assemblies.
If you require technical drawings, dimensional data, or compatibility confirmation for a specific pump serial number, provide the pump model and serial when contacting your service provider so they can verify fit and recommend any associated repair parts (bearings, seals, fasteners) that should be replaced at the same time.
