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 12 electrically connected to the electromagnetic coil 20 projects from the top of the pump body 10. A control unit 14 with a control section for controlling the stroke number is removably mounted on the terminal unit. The pump body 10 is supplied with current from lead pins of a power source connector 64 provided on the control unit 14 through the terminal portion 12. The control unit 14 is prepared according to the specifications of various pump products. Various control units 14 thus can be replaceably mounted on the terminal portion 12 with the pump body 10 as a common component. It is thus possible to provide pump products meeting various specifications. <IMAGE>
