This two-stage rotary vane pump has nominal pumping speed of 72 m3/hr, ultimate base pressure of 0.005 mbar, is equipped with 3 thermistor sensors, vacuum safety valve and magnetic coupling. Configured for 230/400 V (50 Hz), 250-440 V (60 Hz). This pump has been customized for Oxford Instruments and is ideally suited for He3 recirculation in dilution refrigerators as the magnetic coupling provides the highest level of reliability against a costly He3 leak, even when the pump is unused for an extended period. Leak rate <1 x 10-7 mbar l sec-1.
