Dry Roughing Pumps Cat. # $/Each 7901-34 Login

Compact Dry Roughing Pumps

• Reliable, clean, high-performing laboratory and cleanroom dry pumps for inert gas pumping
• Oil-free operation with universal single-phase power featuring multi-stage Roots type pumping concept
• With a frictionless design and no wearing parts, no particulate contamination can result
• No hydrocarbon backstreaming due to lubricant-free pumping module
• Constant pumping speed and ultimate pressure due to constant internal clearances
• With complete overhauls due only every 20,000 hours, maintenance costs are low

These Dry Roughing Pumps are extensively field proven and provide clean, low-maintenance, reliable operation in laboratories and cleanrooms. Their compact design allows for easy integration into any application.

The single-phase frequency converter allows these pumps to be powered in the range of 100 V to 230 V 50/60 Hz through a standard IEC connection with automatic voltage range selection. Rotational speed and pumping speed remain constant regardless of voltage and frequency.

A digital timer gives information about accumulated operational hours for maintenance purposes.

Remote control is facilitated through the Sub-D Connector located at the rear side.

Units are air cooled, so no water supply is required.

Designed for non-corrosive applications:

• Analytical instruments—electron microscopes, surface analyzers, leak detectors, spectrometers
• R&D—particle accelerators and laboratories
• With a frictionless design and no wearing parts, no particulate contamination can result
• Industrial—light bulbs
• Load Locks of clean processes
