Beschreibung
Zusammenfassung:	An eccentric screw pump for delivering fluid and/or granular media. The pump body of the eccentric screw pump includes an inlet region, a pump unit and an outlet region. A drive unit is assigned to the inlet region. The pump unit includes a rotor and a stator, wherein the rotor moves eccentrically in the stator. The inlet region constitutes the suction side and the outlet region constitutes the pressure side of the eccentric screw pump. A bypass connection with at least one safety valve is assigned to the eccentric screw pump in order to take up and return back-flowing medium between the pressure side and the suction side of the eccentric screw pump. The bypass connection and the safety valve may also be integrated into the pump body of the eccentric screw pump.
