ULVAC PMB-D Series Mechanical Booster Vacuum Pump
The ULVAC PMB-D Series is a high-efficiency mechanical booster vacuum pump developed to significantly increase pumping speed in low and medium vacuum applications. When used in combination with oil rotary vacuum pumps, dry vacuum pumps, or liquid ring vacuum pumps, it increases the overall pumping capacity of the system, particularly in pressure ranges where the performance of backing pumps decreases. With its multi-voltage motor option, air-cooled operation capability, and optional atmospheric pressure start feature, it can easily adapt to various industrial processes.
Key Features
- High pumping speed in low and medium vacuum ranges
- International compatibility through a multi-voltage motor option
- Air-cooled operation capability depending on application conditions
- Shorter evacuation times with the optional atmospheric pressure start feature
- Optional special surface coating providing high surface hardness and superior corrosion resistance
- Design compliant with CE and cTUVus standards
- Low maintenance requirements and long service life
Application Areas
PMB-D Series mechanical booster pumps are used in a wide range of vacuum applications where high pumping speed is required:
- Thin film coating systems (Sputtering, Evaporation, Ion Plating)
- Vacuum drying systems
- Freeze drying applications
- Vacuum degassing systems
- Helium leak testing systems
- Analytical instruments and research laboratories
- Gas exchange and gas filling systems
- Vacuum insulation applications
- Heat treatment and melting furnaces
- General industrial vacuum systems
Technical Advantages
The PMB-D Series offers a wide capacity range with PMB100D, PMB300D, PMB600D, PMB1200D, and PMB2400D models. Thanks to its mechanical booster technology, it significantly increases system pumping speed within the pressure range of 10 kPa to 0.1 Pa, resulting in shorter cycle times and higher process efficiency. With the optional inverter-controlled atmospheric pressure start feature, it can operate simultaneously with the backing vacuum pump and significantly reduce system evacuation times.
