Rubber sealing cap according to the present invention and the chemical vertical pressure pump using the same, instead of the protective cap installed in the prior art can double the sealing effect with only the rubber sealing cap contributes to the reduction of the parts as well as to improve the sealing force.

Therefore, it is possible to reduce the product cost and increase the reliability of the product.

1 is a conventional configuration of a conventional chemical vertical pressure pump.
Figure 2 is a cross-sectional view of the main portion of the chemical vertical pressure pump according to the present invention, a partial cross-sectional view.
3 is a cross-sectional view of the bonding state of FIG.

Hereinafter, a rubber sealing cap and a chemical vertical pressure pump using the same according to embodiments of the present invention will be described. The described embodiments are provided so that those skilled in the art can easily understand the spirit of the present invention, and the present invention is not limited thereto. Embodiments of the invention may be modified in other forms within the spirit and scope of the invention. In this specification, 'and / or' is used to include at least one of the components listed before and after.
