ULVAC CR air-cooled multistage dry Roots vacuum pump

ULVAC CR is a multistage oil-free Roots-type vacuum pump with air cooling. The rotors do not touch the cylinder, which gives a stable service life, and no cooling water circuit is required.

The pump complies with CE and cTUVus. The neighbouring ULVAC LR, HR and GR series are selected according to process temperature.

Key features:

• Air cooling — no water circuit needed
• Non-contact rotor–cylinder design
• No oil in the pumping chamber
• CE and cTUVus compliant

Specifications:

• Type: multistage dry, Roots
• Cooling: air
• Rotor–cylinder contact: none
• Oil in pumping chamber: none
• Standards: CE, cTUVus

Application: General industrial vacuum and instruments where water cooling is not available.

Before ordering: Before ordering, specify the required pumping speed, pumped gases and process temperature, which determines the choice between the CR, LR, HR and GR series.
