ABSTRACT:
A cartridge or plug-in pump for use in a fluid holding receptacle such as an aircraft fuel tank. A pump housing on the fluid holding receptacle has an inlet opening to allow passage of fluid from the receptacle into the pump housing. A plug-in pump assembly is axially and rotatably positionable in the pump housing. A pump inlet closure is mounted on the pump housing for movement between inlet open and closed postions. Seals are provided between the pump housing and the pump assembly. A first actuator moves the closure to its inlet closed position in response to rotational movement of the pump assembly relative to the pump housing. A second actuator moves the pump assembly axially relative to the pump housing to break the seals also in response to rotational movement of the pump assembly relative to the pump housing. The first and second actuators are synchronized whereby the closure is in its inlet closed position at the time the seals are broken.
