Zusammenfassung:	A two functional reciprocation pump linear motor lifting device consists of cables, a double-functional pump, a linear motor and oil pipes. The linear motor is in cylinder shape and made by permanent magnetic materials with large thrust and low speed. It is comprised by stator and rotor. The main part of stator is coil and the main part of rotor is permanent magnet. The rotor is connected to the double-functional pump through a bar. The stator coil is power-on through the cables to generate a magnetic field. The magnetic field with the permanent magnet on the rotor moves the rotor so as to drive the pump. This pump is characterized with liquid exhaustion in both procedures of up and down stroke that increase the pumping rate and lower down the pump load.
