The invention discloses a safety pump for efficiently pressurizing heat source gas with energy conservation and belongs to heating equipment. An upper magnetic body and a lower magnetic body are arranged on the upper and lower sides of the external of a pump shell respectively; a protective shell is fixed to the pump shell; a gas outlet valve is fixed in a central hole of the pump shell; an induction magnetic piston is arranged in the pump shell; a sealing ball or a sealing cone seals a channel, for the heat source gas to enter, of a gas inlet cavity; a sealing plate seals a channel, for the heat source gas to enter, of an extrusion cavity; a fixing plug is fixed in a plug hole in the induction magnetic piston; a sealing ball or asealing cone is installed in an inner conical hole; and an accommodating hole is formed in the lower end of the induction magnetic piston. The safety pump for efficiently pressurizing heat source gas with energy conservation has a compact structure, is small in vibration, high in electrical energy utilization rate, strong in power, good in industrial market prospect, high in commercial value and very convenient in both manufacturing and use and is suitable for pressurization transportation of the heat source gas.
