ABSTRACT:
An aquarium pump for use both as an air pump and a water pump, includes an electromagnet, a diaphragm reciprocally driven by the electromagnet, an outer casing in which said electromagnet and said diaphragm are accommodated, an inlet and an outlet each outwardly protruding from said outer casing. The pump has an inlet passage provided in the outer casing, the inlet passage communicating the inlet and an inside of the diaphragm in a fluid-sealed manner, and an outlet passage provided in the outer casing, the outlet passage communicating the outlet and said inside of said diaphragm in a fluid-sealed manner. The inlet, the inlet passage, the inside of the diaphragm and the outlet constitute a fluid-sealed passage so that the aquarium pump functions both as an air pump and a water pump. The aquarium pump may preferably be used for an aquarium apparatus with a passage aquarium.
