Shimadzu TMP-203M NZK052 Turbomolecular Pump

Shimadzu TMP-203M NZK052 Turbomolecular Pump (50,000 RPM)

The Shimadzu TMP-203M NZK052 is a magnetically levitated turbomolecular vacuum pump designed for high and ultra-high vacuum generation. Operating at a rated rotational speed of 50,000 RPM, this unit utilizes momentum transfer mechanics via multi-staged rotor and stator blade assemblies to evacuate process chambers efficiently down to the 10¯8  Pa range.

Key Features

1. Variable Speed Control: Rotational speed can be modulated between 25% and 100% to tune process chamber exhaust metrics precisely.
2. High Throughput Architecture: Optimized blade geometry provides high gas compression ratios for nitrogen, helium, and hydrogen.
3. Robust Thermal Management: Built-in internal water-cooling channels prevent thermal distortion during aggressive continuous industrial cycling.
4. Integrated Gas Purge Port: Standard purge line connection prevents corrosive process byproducts from entering bearing cavities.

Applications

• Semiconductor manufacturing, etching, and thin-film physical vapor deposition (PVD) systems.
• Analytical instrumentation including high-resolution Mass Spectrometry (GC-MS / LC-MS).
• Surface analysis systems (XPS, AES) requiring hydrocarbon-free ultra-high vacuum environments.
• R&D high-vacuum experimental chambers and particle accelerator beamlines.

Frequently Asked Questions

What is the primary function of the 5-axis magnetic bearing in the TMP-203M?

The 5-axis active magnetic bearing levitates the rotor completely without mechanical contact, eliminating mechanical friction, minimizing maintenance intervals, and ensuring zero lubricating oil contamination in the ultra-high vacuum chamber.

Can the rotational speed of the Shimadzu TMP-203M be adjusted?

Yes. The controller allows you to adjust the pump’s rotational speed between 25% and 100% of its rated 50,000 RPM capacity, allowing engineers to tune gas throughput rates relative to specific chamber pressures.

What backing pump capacity is recommended for this turbomolecular pump?

A backing pump with a minimum displacement speed of 160 L/min to 200 L/min (such as a dual-stage rotary vane or dry scroll pump) is recommended to maintain optimal foreline pressure thresholds under continuous gas load conditions.

How do I verify if the unit is compatible with an MKS 325 Moducell setup?

The TMP-203M interfaces via standard I/O control and power cables through its matching controller (e.g., EI-S04M), which can be tied into broader MKS 325 Moducell process automation frameworks using standard interlock signal loops.
