Patent number: 11236747Abstract: An eccentric screw pump for pumping fluids or flowing conveying media from a suction side to a pressure side, which includes a rotor and a stator, the stator being flexible and is connected to the pump housing on one side, in particular on the suction side. The rotor is connected to the drive shaft by means of an articulation. When the eccentric screw pump is in the idle state, there is no sealing contact at least in areas between the rotor and the stator in the sealing areas. When the eccentric screw pump is in the operating state, the stator is surrounded, at least in sections and/or, essentially, on the periphery by the conveying medium. The rotor and the stator are brought into contact with each other in the operating state along the sealing area.Type: GrantFiled: April 10, 2018Date of Patent: February 1, 2022Assignee: NETZSCH Pumpen & Systeme GmbHInventors: Josef Hauck, Hisham Kamal, Reinhard Denk
