The Shimadzu rotor listed here is an original-quality repair part designed for high-speed molecular (turbomolecular) pumps of the TMP-803 / 1003M family and is used in maintenance and upgrades for the TMP-1303 and TMP-1503 series. This rotor is intended as a direct replacement for the TMP-1003 unit and is manufactured to meet the precision and dynamic requirements of turbomolecular pump rotors.
Key features:
- Precision-machined rotor body produced to OEM-level dimensional tolerances for correct fit and reliable balance.
- High-strength, corrosion-resistant materials selected for stability at high rotational speeds and in vacuum environments.
- Dynamic balancing and vibration control optimized for turbomolecular pump operation to minimize bearing stress and extend service life.
- Surface finishes and clearances compatible with molecular flow regimes and vacuum-grade cleanroom assembly procedures.
- Supplied as a repair/original part ready for installation, minimizing downtime during maintenance.
Compatibility and application:
- Primary compatibility: TMP-1003 (direct fit).
- Also applicable when repairing or refurbishing TMP-803 / 1003M type rotors used in the TMP-1303 and TMP-1503 molecular pump series.
- When ordering for complex repairs, verify serial and model numbers to ensure proper matching with your turbopump assembly.
Inspection and quality control:
- Each rotor undergoes visual, dimensional and dynamic balance inspection before shipping.
- Quality checks include runout measurements, balance verification and surface integrity checks to ensure consistent performance in vacuum service.
- Parts are packaged and labelled to preserve cleanliness and prevent mechanical damage during transport and storage.
Handling, installation and maintenance tips:
- Handle the rotor only with lint-free gloves; avoid touching machined surfaces and sealing interfaces.
- Install and align per the pump manufacturer’s service manual; improper torque or misalignment can cause excessive vibration and premature failure.
- Always replace bearings and seals as recommended when performing rotor replacement to ensure optimal pump life.
- Perform a controlled run-in and vibration check after installation to confirm the rotor balance and bearing condition.
Packaging and storage:
- Delivered in protective, vacuum-safe packaging with end caps and corrosion-inhibiting materials when required.
- Store in a clean, dry environment away from strong magnetic fields and mechanical shock.
Why choose this rotor for repair?
- Specifically manufactured as an original-style repair component for Shimadzu turbomolecular pumps, helping preserve pump performance.
- Reduces downtime with a direct-fit replacement and tested balance quality.
- Prepared and inspected to meet the demands of high-speed vacuum systems.
