This product is a genuine replacement component for Shimadzu TMP-2403/W2403 series molecular pumps, supplied as a rotor coating / repair part for the rotating assembly. It is suitable for the wider SHIMADZU TMP-2003–3603 series and is designed to restore original operating performance, rotational balance, and long-term vacuum reliability. Typical use cases are repair service centers, OEM maintenance, and field refurbishments where original-spec surface finish and mechanical tolerances are required.
Key features and purpose:
- Function: precision rotor coating and related rotating assembly repair part to restore rotor surface properties and balance for molecular pumps.
- Compatibility: optimized for TMP-2403/W2403 series and cross-compatible with many models in the SHIMADZU TMP-2003–3603 family.
- Material & finish: proprietary vacuum-compatible coating selected to match original Shimadzu specifications — low outgassing, high hardness, and excellent adhesion to rotor substrate.
- Balance & tolerance: dynamically balanced after coating to meet OEM RPM and vibration limits; dimensional tolerances held to ensure correct clearances in fixed stator housings.
- Traceability: each part is serial-numbered and supplied with inspection records on request.
Note on related DC motor stator (part reference 27000): for assemblies where the rotor coating repair is performed in conjunction with motor maintenance, the DC motor stator (reference 27000) is commonly replaced or inspected to ensure the drive motor’s electromagnetic and thermal performance remains within specification for TMP-2403/W2403 pumps. When ordering a rotor coating repair, check the motor stator condition; many maintenance procedures recommend concurrent stator inspection or replacement to avoid rework.
Technical specifications (typical):
- Applicable pump models: SHIMADZU TMP-2003 ~ TMP-3603 (explicit fit for TMP-2403 / W2403)
- Coating type: vacuum-compatible hard coating (matched to original Shimadzu composition)
- Working balance: meets original OEM balance grade for molecular pump rotors
- Dimensional control: held within micrometer-level tolerances for rotor diameter and axial runout
- Outgassing: low total mass loss (TML) per vacuum-industry standards
Benefits of using the original rotor coating / repair part:
- Restores pump throughput and compression characteristics close to factory condition.
- Reduces risk of contamination and oil backstreaming due to proper surface finish and low outgassing.
- Extends service intervals and reduces unplanned downtime compared to non-OEM or improvised repairs.
- Preserves rotor balance and minimizes vibration that could damage bearings or seals.
Installation and service notes:
- Installation should be performed by trained vacuum-service technicians. Disassembly and reassembly require cleanroom-like procedures to avoid particle contamination.
- After installation, perform dynamic balancing and a run-in under monitored vacuum to verify vibration, ultimate pressure, and leak rates.
- If the DC motor stator (27000) shows signs of wear, overheating, or coating damage, replace or recondition it concurrently to ensure reliable operation.
Packaging, quality assurance and delivery:
- Parts are cleaned, packed in vacuum-safe, anti-static packaging, and shipped with material certificates and visual inspection reports on request.
- Each delivery includes a part identification sheet and recommended torque/assembly notes for reinstallation.
- Lead time varies by stock availability; expedited service and repair turnaround can be arranged for critical spares.
How to order and compatibility check:
Recommendations and warranty:
- Use original replacement or certified repair parts to maintain pump lifetime and performance.
- Parts supplied under repair or replacement typically come with a limited warranty against manufacturing defects and workmanship; contact sales for specific warranty terms.
- Keep service records and rotor serials to track lifetime and plan preventative maintenance intervals.
If you require further technical data, dimensional drawings, or advice on whether to perform rotor-only coating or a full rotor-plus-motor refurbishment (including the DC motor stator 27000), contact our technical sales team with your pump model, serial number, and operating history so we can recommend the correct repair path and provide a quote.
