Abstract

An adaptive eccentric screw pump, which enables, if necessary, an increase of the output, the pressure and/or the simultaneous output of more than one output medium, and wherein the eccentric screw pump has comparably low energy consumption and the production and maintenance expenditure thereof is kept low. For this purpose, the eccentric screw pump is equipped with a modular output system, including at least two output modules having in each case one rotor and one stator, wherein the output modules are coupled to one another and merely one actuation unit is associated with the output system, and wherein the output system for an output medium has more than one inlet and/or outlet or at least one modular perfusion housing.

Claims

exact text as granted — not AI-modified
1 . An eccentric screw pump with a modular delivery system, comprising at least two delivery modules comprising in each case a rotor and a stator, wherein the delivery modules are coupled together and only one drive device is assigned to the delivery system and wherein the delivery system comprises more than one inlet and/or outlet or at least one modular through-flow housing for the delivery medium. 
     
     
         2 . The eccentric screw pump according to  claim 1 , wherein the delivery modules are coupled together in each case by a suction housing, a pressure housing or a through-flow housing. 
     
     
         3 . The eccentric screw pump according to  claim 1 , wherein the rotors of the delivery modules are coupled together in the suction housing or pressure housing by a rigid connection. 
     
     
         4 . The eccentric screw pump according to  claim 3 , wherein the rotors are coupled together detachably. 
     
     
         5 . The eccentric screw pump according to  claim 1 , wherein the rotor for the delivery modules is constituted in one piece. 
     
     
         6 . The eccentric screw pump according to  claim 1 , wherein a specific mixing ratio of the delivery media can be fixed by the selection and configuration of the delivery modules. 
     
     
         7 . The eccentric screw pump according to  claim 1 , wherein the axial force acting in the direction of the drive device approaches zero. 
     
     
         8 . The eccentric screw pump according to  claim 1 , wherein the delivery modules are disposed in series. 
     
     
         9 . The eccentric screw pump according to  claim 1 , wherein two adjacent delivery modules are coupled together by a suction housing or a pressure housing and are constituted for mutually opposite delivery directions. 
     
     
         10 . The eccentric screw pump according to  claim 1 , wherein two adjacent delivery modules are coupled together by a through-flow housing and are constituted for identical delivery directions. 
     
     
         11 . The eccentric screw pump according to  claim 1 , wherein the delivery system comprises two delivery modules. 
     
     
         12 . The eccentric screw pump according to  claim 11 , wherein the delivery system comprises a pressure housing and a suction housing. 
     
     
         13 . The eccentric screw pump according to  claim 11 , wherein the delivery system comprises a pressure housing and a through-flow housing. 
     
     
         14 . The eccentric screw pump according to  claim 1 , wherein the delivery system comprises four delivery modules. 
     
     
         15 . The eccentric screw pump according to  claim 14 , wherein the delivery system comprises two suction housings and two pressure housings. 
     
     
         16 . The eccentric screw pump according to  claim 14 , wherein the delivery system comprises a suction housing, two through-flow housings and a pressure housing. 
     
     
         17 . The eccentric screw pump according to  claim 1 , wherein means for mixing coupled with the rotor are disposed in the coupling region of the delivery modules. 
     
     
         18 . The eccentric screw pump according to  claim 17 , wherein the means for mixing are disposed in the pressure housing. 
     
     
         19 . A housing for a delivery system of an eccentric screw pump according to  claim 1 .
