Abstract (en)
[origin: EP2216550A2] The pump (10) has shaft journals (18B) rotatably connected with a drive gear (16A) and rotatably mounted in housing covers (14A, 14B) at both sides of the drive gear. A shaft seal (26) controls leakage of fluid to be pumped and seals an actuator pivot (18A) with respect to one of the housing covers penetrated by the actuator pivot. The shaft seal is arranged at an inner side of one of the housing covers that is penetrated from the actuator pivot, where the inner side faces the drive gear and another drive gear (16B).
