turbo molecular pump utm-B series
Turbo Molecular Pump UTM-B SERIES The compound turbo molecular pump with the ceramic ball bearings,and has excellent compression ratio. Compact design by integrated controller design. Excellent high back pressure performance allows to use smaller backing pump.
Features
- No limitation in the mounting direction The degree of freedom in system design is high because of free mounting direction.
- On-board controller Integrated controller to the pump body is capable to reduce wire work and downsize pumping system.
- High compression ratio and high back pressure High compression ratio made it possible to run the pump at high back pressure and downsize its backing pump.
- Three kinds of flange Inlet port flange is selectable from ISO100-K, ICF152, and VG100.
- Clean vacuum environment Less back flow of hydrocarbon gases while both the pump is running and stopping.
- Low noise Noise level at the no load is 50dB or less（with ISO-100K flange）
- Applicable standard CE and NRTL
applications
- Main pumping system for analytical equipments, R&D systems, experimental devices, etc.
- Main pumping system for evaporators and sputtering systems, etc.
- Main pumping system to evacuate low molecule gases such as H2, He

Note Turbo Molecular Pump UTM-B SERIES
*1 Inlet flange is from VG100, ICF152 and ISO100-K when ordering.
*2 Baking is available only for forced air cooling type with ICF flange.
*3 Value at the time of the ambient air temperature is 25℃. If ambient air temperature changes, an acceptable value will change.
*4 Maximum outlet pressure and maximum inlet pressure can not be satisfied at the same time.
*5 Maximum inlet port pressure which can accept continuous running.
*6 Maximum pressure at exhaust port which can accept continuous running when gas flow coming from inlet port is 0 mL/min.
*7 Value when ambient temperature is 5~25℃. In addition, N2 should be used for gas purge and its flow rate should be 0.4mbarL/sec(25sccm).
*8 Select appropriate backing pump not to maintain exhaust port pressure less than maximum exhaust port pressure when gas flow increases.
*9 Do not flow reactive gas, corrosive gas, and gas includes Gallium. Please contact us when using other gases.
*10 This value is measured by ULVAC standard for ISO flange type.
