Document Type and Number:
WIPO Patent Application WO/2022/164034
Kind Code:
A1
Abstract:
The present invention relates to a long-life non-contact pump comprising: a pump cylinder having a predetermined pumping space; an inlet valve and an outlet valve located on one part of the pump cylinder to prevent backflow of a fluid and enable inflow and outflow of the fluid; a bellows provided in the pumping space of the pump cylinder to change the volume of the pumping space so as to pump the fluid flowing in and out through the inlet and the outlet; and a reciprocation drive unit provided on the outer side of a cylinder cover to reciprocatively drive a piston along a connected reciprocating rod. The purpose of the non-contact pump is to maintain the airtightness by means of a pumping operation without friction of components, prevent a generation of foreign materials in the fluid due to friction, and improve the replacement cycle of expendable components.
