How does the lotion pump work

The function of lotion pump is very like an air suction device. It pumps the product from the bottle to the consumer’s hands, although the gravity law tells it to the contrary. When the user presses the actuator, the piston moves to compress the spring, and the upward air pressure draws the ball up into the dip tube and then into the chamber. When the user releases the actuator, the spring returns the piston and actuator to their up position and the ball to its resting position, sealing the chamber and preventing liquid product from flowing back to the bottle. This initial cycle is called “startup”. When the user presses the actuator again, the product already in the chamber will be drawn out of the chamber through the valve stem and actuator and distributed from the pump to the consumers. If the pump has a larger chamber (common for high output pumps), additional oil filling may be required before the product is distributed through the actuator.

Washer pump output

The output of plastic lotion pump is usually in cc (or ml). Typically in the range of 0.5 to 4cc, some larger pumps have larger chambers and longer piston/spring assemblies with outputs up to 8cc. Many manufacturers offer multiple output options for each lotion pump product, giving product marketers complete control over dosage.
