1. Pump body
Lotion pump is mainly composed of pump body and drive device. The pump body is the main structure of lotion pump, which is usually composed of impeller, pump body, seals and other parts. The pump body is the part that sucks out materials from the container, and its internal channels are connected to the pipes in the container, which can suck out liquid and deliver it to the place where the user needs it.
2. Impeller
The impeller of lotion pump is a rotating part in the pump body, which mainly plays the role of sucking in and pressing out liquid. The impeller is usually composed of multiple blades. When the driving device is started, the blades begin to rotate, generating a certain centrifugal force to suck the liquid into the pump body and push it out.
3. Sealing
The seals of the lotion pump help to keep the liquid inside the pump body from leaking out, which is especially important for some volatile or oxidizable liquids, and can prevent the deterioration of liquid in contact with air. Common sealing materials include rubber, silicone, etc.
4. Drive device
The driving device is the source of rotation for the pump body, and there are two common driving devices: manual and electric. Manual pumps require manual lifting of the handle to achieve rotation, while electric pumps achieve rotation through motor rotation, and their working efficiency is higher than that of manual pumps.
Lotion pumps are mainly used in cosmetics, shampoo, shower gel, hand sanitizer, detergent, beverage, food, medicine and other fields, and lotion pumps are also used in some occasions requiring accurate measurement.
