Abstract (en)
[origin: EP2634366A2] The pump (10) has a screw thread with screw (38) that is provided in a connection hole (37) for locking an attachment element (27) and a gear wheel (26). The gear wheel and the attachment unit are rotated in opposite directions using the connection hole so that backlash between edges of feed screws (17,18) is adjusted. An opening is formed in gear section (14) of pump housing (11) and is covered by a lid which is released in mounted state of the pump.
