An electromagnetically driven reciprocating pump characterized in that the pump cover is made of a damping steel plate and the pump part is screwed onto the pump cover.

Claims

[Scope of utility model registration request]

The pump includes an electromagnet part fitted in the cylindrical yoke, a switch device that cuts off and on energization of the electromagnet part in conjunction with the operation of the electromagnet part, a pump base, a pump body, and a pump cover, and is screwed onto the yoke. What is claimed is: 1. An electromagnetically driven reciprocating pump comprising: a pump section attached to the pump cover and driven by the electromagnetic section, wherein the pump cover is screwed onto both surfaces of the pump cover with elastic material interposed therebetween.
