A digital display screw pump comprises a screw pump body and is characterized in that: an information emitting disc, which is used for magnet installation, is fixedly arranged on the driving shaft of the screw pump body; a magnetic information sensor is fixedly arranged at the same longitudinal position of the information emitting disc on the external side of the information emitting disc; the magnetic information sensor is connected to the signal output terminal of a data processor through a wire; and the signal output terminal of the data processor is connected to the input terminal of a digital display. The digital display screw pump has the advantages of simple assembly, high measuring accuracy, low cost, convenient maintenance, and excellent performance; can be applied to promotion and applications in automation, factory formula quantitative measurement, and medium measurement.
