ULVAC PMB Series Mechanical Booster Vacuum Pump

The ULVAC PMB Series is a high-performance mechanical booster vacuum pump developed for use in various industrial applications. When used in combination with dry vacuum pumps, oil rotary vacuum pumps, or liquid ring vacuum pumps, it significantly increases pumping speed within the pressure range of 10 kPa to 0.1 Pa, where the performance of backing pumps decreases. Thanks to its high-efficiency motor design and wide range of applications, it provides reliable performance in many vacuum processes.

Key Features

• Compatibility with different power infrastructures through a high-efficiency multi-voltage motor option
• Air-cooled operation capability depending on the application
• High corrosion resistance through special anodized coatings applied to key components
• Durable structure resistant to wear and scratches thanks to high surface hardness
• Shorter evacuation times with the atmospheric pressure start-up option
• Optional explosion-proof motor configurations
• Design compliant with international standards and a reliable operating principle

Application Areas

PMB Series mechanical booster pumps are used in a wide range of vacuum applications where high pumping speed is required:

• Evaporation systems
• Sputtering and ion coating processes
• Vacuum drying systems
• Freeze drying applications
• Vacuum degassing systems
• Analytical instruments and leak testing systems
• Gas exchange and gas filling applications
• Vacuum insulation systems
• Heat treatment and melting furnaces
• General industrial vacuum systems

Technical Advantages

The PMB Series covers a wide range of applications with various capacity options. When used together with backing pumps, it significantly increases the overall pumping performance of the system, reducing process times. Thanks to its corrosion-resistant structure, high-efficiency motor technology, and optional atmospheric pressure start-up capability, it provides a reliable and efficient vacuum solution for semiconductor, thin-film coating, laboratory, and industrial manufacturing applications.
