Compatibility and model notes
This stator is intended for the Shimadzu TMP series molecular pumps and is commonly used in maintenance and repair of TMP-2003 through TMP-3603 models. If your pump model is TMP-3003 ~ TMP-3603, this part has been widely used as the direct repair component. To confirm fitment for a specific serial number or sub-model, consult the pump service documentation or request a compatibility check through our parts service: Shimadzu molecular pump non-standard maintenance parts.
Installation guidelines (summary)
- Work must be performed by qualified service personnel familiar with molecular pump disassembly and motor assembly procedures.
- Ensure the pump is fully isolated from power and the vacuum chamber is vented and safe to service.
- Document rotor orientation and rotor-stator axial clearance before removal.
- Remove motor end covers and carefully extract the rotor assembly to expose the stator.
- Install the new stator ensuring correct alignment of mounting holes, connectors and any sensor pickups.
- Verify electrical connections, insulation continuity, and phase wiring before reassembly.
- After reassembly, perform a low-speed spin test and vibration check prior to returning the pump to service.
Testing and quality checks performed before shipment
- Visual inspection for winding integrity and insulation coating
- Resistance and phase-to-phase balance measurements
- Dimensional inspection of critical mounting surfaces
- Basic run-in and balance verification where applicable
Troubleshooting after replacement
- If the motor fails to start: check wiring and controller compatibility, inspect connectors, and verify motor controller firmware supports the pump model.
- If excessive vibration occurs: verify rotor-stator axial clearance, check rotor balance and bearing condition, and confirm correct assembly torque values.
- If unusual noise or heating: confirm insulation continuity, measure winding resistances, and ensure adequate cooling path in the pump housing.
Packaging, delivery and spare part ordering
- Each stator is cleaned, wrapped, and packed in protective anti-static and anti-corrosion materials to prevent contamination and damage during transport.
- Available for single-piece replacement or bulk spares for service centers.
- To order repair parts or to request a quote, refer to our parts listing and service options at Shimadzu molecular pump non-standard maintenance parts.
Warranty and service support
- Parts are supplied with a standard supplier warranty against manufacturing defects (terms vary by order and region).
- Installation by qualified service personnel is recommended to preserve warranty.
- Support for installation guidance, compatibility checks, and return/repair processing is available through our service desk.
Safety and handling
- Handle the stator and windings with care to avoid mechanical shocks that could damage winding insulation.
- Avoid exposure to liquids or aggressive chemicals which can degrade insulation and coatings.
- Follow all electrostatic discharge (ESD) precautions when handling electronic components and connectors.
