ATH 2804 M and 3204 M

Product catalog summary

Overview: The document provides detailed information about the ATH 2804 M and ATH 3204 M compact, magnetically levitated turbopumps, which are designed for high-performance applications requiring a pumping speed of 3,000 l/s. These pumps are suitable for harsh environments due to their high gas throughput and temperature tolerance.

Customer Benefits:

High gas throughput and temperature operation for demanding applications.
Exhaust pressure tolerance up to 3.4 mbar.
Low vibration operation with automatic out-of-balance compensation.
Compact design for space-saving installation.
Integrated drive electronics for versatile applications.
Easy installation and start-up.
Energy-efficient with low electricity and cooling water consumption.

Technical Specifications:

Gas throughput: Over 5,000 sccm for nitrogen and up to 1,500 sccm for argon at 65°C.
High temperature operation: Up to 85°C for aggressive applications.
Dimensions: ATH 2804 M/MT - D 335 mm, H 347 mm; ATH 3204 M/MT - D 425 mm, H 275 mm.
Pumping speeds: N2 - 2,350 l/s (ATH 2804 M), 3,050 l/s (ATH 3204 M); Ar - 2,350 l/s (ATH 2804 M), 2,900 l/s (ATH 3204 M).
Rotation speed: ±2% at 25,000 min-1.
Run-up time: Less than 8 minutes.
Compression ratios: N2 > 1 · 10⁸, Ar > 1 · 10⁹, He 9 · 10⁴, H2 4.9 · 10³.
Cooling: Water cooling with 1 l/min consumption at 15 – 25°C.
Sound pressure level: ≤ 45 dB (A).
Operating voltage: 220 – 240 V AC; 50/60 Hz, single phase.

Design and Operation:

5-axis magnetic levitation for wear-free, low vibration operation.
Maintenance-free bearings requiring no lubrication.
Integrated drive electronics for easy plug-and-play installation.
Flexible mounting orientation.
