How to choose the appropriate pump head for your product？

Jin Yu(金裕) Plastic Packaging is a professional manufacturer specializing in the production of various customized packaging for cleaning and personal care products, cosmetic bottles, spray bottles, vacuum bottles, furniture cleaning packaging, food packaging, etc. In fact, the cap of the bottle, the pump head, and the bottle are all equally important, as they directly affect the user experience and product positioning. This time, we will provide some explanations on how to select the appropriate pump head for your products.

Pump head type When choosing the pump head based on the product requirements, there will be the following several situations：

Standard liquid pump - The use of the reciprocating motion of the piston to convey liquids is more suitable for products such as hand sanitizer, body wash, and shampoo.

Spray pump - It is a device that utilizes the principle of atmospheric equilibrium. By pressing it, the liquid inside the bottle is sprayed out and atomized, suitable for use in toner, alcohol spray, facial spray liquid, furniture cleaning liquid, car care liquid and edible oil spray, etc.

lotion pump - When the push button is pressed, the push button drives the pump core assembly to move down, and the air inside the cylinder is discharged through the liquid outlet channel connected to the push button in the pump core assembly. When the push button is released, under the action of the reset spring, the pump core assembly moves up. At this time, the piston moves down by friction with the inner wall to close the liquid outlet hole, and the internal liquid storage cavity forms a negative pressure. The liquid in the bottle is sucked into the liquid storage cavity through the liquid suction pipe under the action of atmospheric pressure. Press the push button again, the piston moves down, the liquid outlet channel in the pump core assembly opens, and the liquid is sprayed out from the liquid outlet hole of the push button under the action of pressure. It is suitable for hair masks, exfoliating scrubs, hand creams, essence lotions, and cooking seasonings, etc.

Foam pump - The piston creates a vacuum pressure, and the liquid is drawn out from the bottle through the suction tube. The incoming liquid and air collide at high speed in the mixing chamber, forming a dense and uniform foam. It is suitable for hand sanitizer, facial cleanser, shaving foam, and foamy cleaners.

Non-air Pump (Vacuum Pump) - The airless pump directly atomizes and sprays the liquid medium through a piston or diaphragm pressurization device. It can handle high-viscosity fluids. Its working principle is to isolate the product from air and form a sealed vacuum chamber. For beauty and skincare products containing active ingredients such as retinol and vitamin C, such as serums, creams, and lotions, the airless pump can effectively protect the stability of their components and prevent oxidation degradation. The complex piston mechanism can provide precise and controlled dosing, ensuring a consistent product volume each time. This is very suitable for some products that require precise dosing, such as medicines and cosmetics, and can ensure the effectiveness and safety of the products.
