The invention discloses an energy-saving and environment-friendly pump for vacuum pumping and belongs to the field of vacuum servo and the field of vacuum pumping of automobile braking. An electromagnetic coil is installed in a protection shell of the energy-saving and environment-friendly pump for vacuum pumping and is arranged outside the lower portion of a negative-pressure shell. The annular inner end of the protection shell is fixed to the outer face of the negative-pressure shell. A gas outlet valve is fixed in a center hole of the negative-pressure shell. A pushing spring and a magnetism induced piston are arranged in the negative-pressure shell. The pushing spring is pressed on the magnetism induced piston. A gas pumping channel of a gas pumping cavity is sealed through a sealing cone or a sealing ball, and a gas pumping channel of a gas extruding cavity is sealed through a sealing cap. A gas distribution limiting plate is fixed in a limiting hole in the upper end of the magnetism induced piston. A sealing cone or a sealing ball is installed in an inner cone hole of the magnetism induced piston. The energy-saving and environment-friendly pump for vacuum pumping is compact in structure, low in vibration, high in power, high in electric energy utilization rate, high in vacuum pumping efficiency, suitable for installation and use of automobiles driven by internal combustion engines and electric automobiles and use of industrial vacuum pumping, good in market prospect and beneficial to industrial production.
