In Alpha Magnetic Spectrometer-02 (AMS-02) experiment a large scale superconducting magnet separates charged particles coming from cosmic radiation. Two thermo-mechanical pumps (TMP), operating by use of the Fountain-effect, will be used to supply the current leads and the magnet coil after quench with superfluid helium. These TMP are currently under development at ILK Dresden. Due to the applications the TMP are required to pump a mass flow of 0.2 g/s. After introduction into the basic principles essential for TMP function, we report on the development and tests of the TMP for AMS-02.
