Oxygen, sunlight and microorganisms often exposed to cosmetics during storage and use will change their characteristics, causing odor, discoloration or pollution. Once opened, this will shorten the shelf life of the product and reduce its quality and effectiveness. Airless packaging helps prevent products from coming into contact with air and contaminants during filling, storage, and use, thereby improving service life and preservation quality.



2. Since airless packaging has almost no risk of pollution and degradation, manufacturers can reduce the use of preservatives, thereby making the product more organic. This is a great advantage, especially in the case of natural products. In fact, some cosmetics can only be packaged in airless cosmetic bottles.



3. Airless packaging avoids waste, because consumers can use the product until the last drop. The precision pumps and other mechanical devices used in airless packaging can evenly and accurately dispense products during each use even in...    less

This is the advantage of the vane pump. It can reduce the manpower used in our daily life and replace the manpower with machinery to improve production capacity.

During the installation process, some details may be ignored and the vane pump is incorrect, resulting in no pressure and no power output in the pump. The management points of vane pump should prevent dry rotation and overload, prevent air intake and excessive suction vacuum.

1. When the direction of the pump changes, the direction of suction and discharge will also change. The vane pump has a prescribed direction and does not allow reverse rotation. Because the rotor groove is inclined, the blade is chamfered, the bottom of the blade is connected to the oil discharge chamber, and the throttle groove and the suction and discharge port on the oil...    less
