Shimadzu Screw Stator 3000 Original Parts Repair for TMP 3203 3403 Series Molecular Pump

The Screw Stator 3000 is an OEM repair component designed for Shimadzu turbomolecular pump series TMP-3203 through TMP-3403 and is dimensionally compatible across the wider SHIMADZU TMP-2003–3603 family. Manufactured to meet original equipment tolerances, this stator element restores internal clearances and surface geometry that are critical for stable high-speed rotor operation and optimal vacuum performance.

Key features

• Direct replacement for Shimadzu Screw Stator 3000 — engineered for seamless fit in TMP-3203~3403 models.
• Precision machining and tight manufacturing tolerances to preserve rotor/stator clearance and reduce leak paths.
• High-grade materials selected for dimensional stability under thermal cycling and long service life.
• Surface finishes and coatings appropriate for vacuum service to limit outgassing and particulate generation.
• Supplied as an original-equivalent repair part suitable for workshop rebuilds or field swaps.

Compatibility

Applicable models (representative): SHIMADZU TMP-2003 through TMP-3603, specifically intended for TMP-3203 ~ TMP-3403 series rebuilds and component-level repairs. If you need confirmation for a particular model or serial number, provide the pump nameplate data for verification.

Materials & manufacturing

The Screw Stator 3000 is produced using vacuum-compatible metallurgy and industry-standard machining practices. Critical surfaces are finished to reduce friction and particle generation; parts are cleaned and packaged in a clean environment to preserve integrity prior to installation. Where applicable, anti-corrosion or low-friction coatings are applied according to OEM specifications.

Installation & fitment guidance

• Handle with clean gloves to avoid contamination; ensure the pump internals are free of debris prior to assembly.
• Follow the pump manufacturer's rebuild sequence—align stator features carefully and avoid forcing parts that do not seat smoothly.
• Do not attempt to machine or modify the stator without engineering approval; any alteration can compromise vacuum performance and rotor balance.
• After assembly, perform recommended leak checks, spin/balance verification and run-in procedures per Shimadzu service instructions.

Inspection & maintenance

• Inspect the stator for scoring, abrasion or deformation whenever the pump is opened for service.
• Replace the stator if wear increases rotor/stator clearance beyond specification or if surface defects are visible.
• Clean with solvents compatible with stator materials and vacuum systems; avoid aggressive chemicals that can leave residues or attack coatings.
• Keep a record of service intervals—timely replacement reduces the risk of rotor contact and catastrophic failure.

Performance impact

A correctly fitted Screw Stator 3000 restores the internal geometry and sealing performance that directly influence ultimate pressure, throughput and rotor stability. Using original-equivalent stators reduces vibration, lowers wear on rotor and bearings, and helps the pump meet its rated pumping curve reliably after a rebuild.

Quality assurance, packaging & supply

Each stator is inspected for dimensional conformity and cleanliness before shipment and is double-packed to prevent contamination or mechanical damage. For traceability, supplier batch information and inspection records can be provided on request. Warranty and return terms follow the supplier's standard commercial policies; contact the parts provider for details.
