Electromagnetically operated fixed displacement pump

摘要

An electromagnetically operated fixed displacement pump is sought, which can cope with diversification of electromagnetically operated fixed displacement pump products, and internationalization of their destination, readily permits cost reduction by mass production and permits efficient supply and control of products. A terminal portion electrically connected to the electromagnetic coil projects from the top of the pump body. A control unit with a control section for controlling the stroke number is removably mounted on the terminal unit. The pump body is supplied with current from lead pins of a power source connector provided on the control unit through the terminal portion. The control unit is prepared according to the specifications of various pump products. Various control units thus can be replaceably mounted on the terminal portion with the pump body as a common component. It is thus possible to provide pump products meeting various specifications.
