Date Oct. 5, 1995A pump including a first enclosure (10) and a second enclosure (20), a pumping mechanism (3) and an electromotive means (11,23) operable to drive the pumping mechanism (3). The electromotive means (11,23) includes a solenoid assembly (11) having a solenoid coil (13), and an armature assembly (23), the solenoid coil (13) being sealed within the first enclosure (10). The pump mechanism (3) is supported within the second enclosure (20), the armature assembly (23) being in operational relationship with the pumping mechanism (3). A diagnostic sensor (19) is sealed within the first enclosure (10) for detecting flow through a flow path (22) in the second enclosure (20). A flow responsive member (28) is supported within the flow path (22), the diagnostic sensor (19) detecting displacement of the flow responsive member (28).
