Shimadzu GA Unit of Motor Stator Original Parts Repair for TMP 2203 Molecular Pump

This listing describes the GA Unit of the Motor Stator — an original repair part designed for the Shimadzu TMP-2203 molecular pump family. The unit is supplied as a complete motor stator assembly intended for direct replacement in affected pumps, restoring motor performance and mechanical integrity without the need for extensive on-site rewinding or rework.

Overview

The GA Unit of Motor Stator is an OEM-quality assembly used to service and rebuild Shimadzu TMP-2003~3603 series molecular pumps, including the TMP-2203LMTG and related TMP-2203 variants. Supplied as an original parts repair component, the assembly includes the stator core, windings, insulation, mounting interfaces, and connectors matched to factory tolerances for fit and alignment.

Key Features and Benefits

• Factory-matched replacement: Designed to match original Shimadzu specifications for direct drop-in replacement.
• Complete assembly: Delivered as a fully assembled stator unit to minimize downtime and simplify service procedures.
• High-quality insulation and winding: Ensures electrical reliability and longer service life compared with field repairs.
• Precision fit: Mounting surfaces and connector placements align with TMP-2203 mechanical interfaces to preserve rotor clearance and balance.
• Tested before shipment: Each unit is inspected for continuity, insulation resistance, and dimensional accuracy.

Compatibility

Compatible models: SHIMADZU TMP-2003 ~ 3603 series, with specific application to TMP-2203 and TMP-2203LMTG variants. If you are repairing a TMP-2203 series pump, replacing the motor stator with this GA Unit restores original motor geometry and electrical characteristics.

Typical Applications

• Service centers performing original parts repairs and rebuilds
• Laboratories and production facilities seeking to return TMP-2203 pumps to OEM performance
• Situations where field rewind is impractical or where OEM tolerances must be preserved

Replacement and Installation Notes

1. Disconnect the pump from power and any connected systems. Allow rotating elements to cool and spin down fully.
2. Remove the pump housing and rotor per Shimadzu service manual instructions, taking care to preserve axial and radial clearance settings.
3. Extract the damaged stator unit and inspect the rotor, bearings, and sealing surfaces for collateral wear or contamination.
4. Install the GA Unit stator assembly, ensuring correct alignment and torque on mounting fasteners as specified by the service manual.
5. Reconnect electrical connectors and verify insulation resistance before energizing the pump.
6. Perform a balanced run-in and leak check in accordance with Shimadzu guidelines.

Quality Assurance and Testing

Each motor stator assembly is supplied after passing routine quality checks: visual inspection, dimensional verification, insulation resistance measurement, and continuity testing. Where applicable, dynamic fit verification is performed to confirm rotor-stator clearances within factory tolerances.

Storage and Handling

• Store in a dry, temperature-controlled environment and avoid exposure to corrosive atmospheres.
• Handle the assembly by its mounting points; avoid contact with the winding surfaces and insulation.
• Keep the unit in original packaging until ready for installation to prevent contamination.
