ULVAC GV Series Magnetically Coupled Oil Rotary Vane Vacuum Pump

The ULVAC GV Series is a magnetically coupled two-stage oil rotary vane vacuum pump developed for laboratory, analytical, and industrial applications. Thanks to its non-contact magnetic coupling technology, power is transmitted between the motor and the pump without the use of a mechanical shaft seal, completely eliminating the risk of oil leakage at the power transmission section. With its low noise level, high vacuum performance, and anti-suckback mechanism, it provides a clean, reliable, and long-lasting vacuum solution.

Key Features

• Non-contact power transmission with magnetic coupling technology that prevents oil leakage
• High vacuum performance with a two-stage rotary vane design
• Anti-suckback mechanism that protects equipment during power failures
• Stable operation in applications involving water vapor thanks to the gas ballast system
• Quiet operation, making it ideal for laboratory and analytical environments
• Safe operation with a built-in thermal protection system
• Compact design, easy maintenance, and long service life

Application Areas

GV Series vacuum pumps are preferred in a wide range of laboratory and industrial applications requiring clean and reliable vacuum:

• Analytical instruments
• Electron microscope systems
• XRD and XRF analytical instruments
• Helium leak testing systems
• Backing pump applications for turbomolecular pumps
• Vacuum coating systems
• Laboratories and research centers
• General industrial vacuum applications

Technical Advantages

The GV Series offers solutions for different capacity requirements with the GV135 and GV200 models. With pumping capacities ranging from approximately 135 L/min to 240 L/min, the series stands out with its ultimate pressure of up to 0.5 Pa, low noise level, and magnetic coupling technology. Thanks to its oil leak-free design, anti-suckback system, and reliable mechanical construction, it delivers high performance and long-term operation across a wide range of applications, from laboratories to advanced technology manufacturing facilities.
