Definitions

  • the linear motor 34 comprises a stator 40 and a mobile part 42 displaceable according to the effect of the field magnetic generated by the stator.
  • the stator 40 is mounted outside the casing 20 inside of chamber 26.
  • Tubing 20, at least in region 43 adjoining the linear motor 34, is formed of material non-magnetic, which, in a preferred example, is ceramic.
  • the mobile part 42 is provided, at its end upper of a hooking head 44 which allows to go up on the surface, for example by means of a cable, the part mobile 42 as well as pump 30.
