description The invention discloses a safety screw pump. The safety screw pump comprises a pump body. A rotor of the pump body comprises a framework and a nonmetal layer which wraps and is fixed to the outer portion of the framework. The framework and a stator of the pump body are both made of metal materials. The safety screw pump is good in heat conductivity, heat dissipation is facilitated, and the work temperature of the pump body is reduced; and the matching precision and using performance of all components are guaranteed, and the service life is prolonged. The abrasion between the rotor and the stator of the screw pump is reduced, meanwhile, sparks between the rotor and the stator are avoided, and the screw pump can be used for conveying inflammable materials. The application range is enlarged, conditions are created for the metal materials to manufacture the stator, and the safe and stable running of the screw pump is facilitated.
