Eccentric screw pump with telescoping housing

An eccentric screw pump comprising:

• a stator;
• a rotor rotatable in the stator about an axis;
• a drive for rotating the rotor about the axis;
• a pump housing connected with the stator and having at least one port for intake or output of a medium to be conveyed;
• a drive-connection housing provided between the pump housing and the drive;
• a drive shaft connected with the drive and in the drive-connection housing;
• a drive-side coupling connected to the drive shaft of the drive;
• a rotor-side coupling connected to the rotor;
• a coupling rod in the pump housing and connected with the drive shaft by the drive-side coupling and with the rotor by the rotor-side coupling;
• a drive-side housing connector connected between the pump housing and the drive-connection housing, surrounding the drive-side coupling, and having a section that is fixed and a movable section that is telescopically and axially displaceable toward the at least one port of the pump housing into a disassembly position with the moveable section axially in or on the fixed section to fully expose the drive-side coupling and axially away from the at least one port from the disassembly position into a functional position surrounding and protecting the drive-side coupling;
• a stator-side housing connector connected to the stator and the at least one port being between the drive-side housing connector and the stator-side housing connector;
• and
• a support engaged to the coupling rod to support the coupling rod in the disassembly position of the drive-side housing connector.
