<p>A pump comprises a first enclosure and a second enclosure, a pumping mechanism (3) and an electromotive means operable to drive the pumping mechanism (3). The electromotive means includes a solenoid assembly having a solenoid coil (13) and an armature assembly (23), the solenoid coil (13) being sealed within the first enclosure. The pumping mechanism (3) is supported within the second enclosure, and the armature assembly (23) being in operational relationship with the pumping mechanism (3). A diagnostic sensor (19) is sealed within the first enclosure for detecting fluid flow through a flow path in the second enclosure. A flow-responsive member (28) is supported within the flow path, the diagnostic sensor (19) detecting displacement of the flow-responsive member (28).</p> |
