Shimadzu TMP B70 Turbo Pump

The Shimadzu B70 Turbo Pump is a high-performance, compact, and reliable 70l/s turbomolecular pump designed for demanding vacuum applications. It offers excellent pumping speed and compression ratios suitable for a wide range of processes in research, industry, and electronics. This size of pump is typically suitable for smaller vacuum chambers such as load locks. Key advantages include:

  • Combination of ceramic and magnetic bearings for long service intervals and lower running costs
  • Suitable for UHV pressures in combination with a small dry backing pump
  • Integrated controller allows simple push button operation, or optional display unit for detailed operating information
  • High compression ratio for optimised operation with light gases
  • Mountable in any orientation
  • Fast delivery times
  • Low power consumption and heat generation

Key Features


  • Pumping speed (N2/He/H2): 70/60/49 l/s
  • Available mounting: DN63CF, ISO63-K, KF40
  • Option for no cooling / air cooling / water cooling (affects maximum allowable gas flow)
  • Compression ratio (N2/He/H2):  >1×109/4×107/4×105
  • Maximum allowable N2 gas throughput without cooling: 15sccm at 25ºC, 10 sccm at 35ºC
  • Addition of the optional air cooling fan increases this to 40sccm and 30sccm respectively
