PROBLEM TO BE SOLVED: To facilitate pump replacing work and the reuse of it by a method in which a pump main body is made to be replaced easily to a metal can through a pump fixing member, and the fixing member is made to be combined freely attachably/detachably with a binding part on the periphery of the end part of the can. SOLUTION: A pump main body 4 which is fixed freely attachably/detachably through a pump fixing member 3 is provided, and the member 3 is combined with a clamp part 5 on the periphery of the end part of a metal can 2. The fixing member 3 is constituted from a roof part 33, a binding part 31, and a pump fixing cylinder 32, and a fixing ring 7 is screwed to the outside of the outer wall part 37 of the binding part 31. In metal can 2 replacing work, the binding part 31 at the lower end of the fixing member 3 is separated from the clamp part 5. The ring 7 is turned to remove the screw bond between it and the outside of the outer wall part 37, the ring 7 is removed from the outer wall part 37, and the binding part 31 is removed by pulling it upward. |
