A lotion pump acts much like an air suction device that draws the product from the bottle to the consumer’s hand despite the law of gravity telling it to do the opposite. When the consumer presses down on the actuator, the piston moves to compress the spring, and the upward air pressure draws the ball upwards, along with the product inside, into the dip tube and subsequently the chamber. As the user releases the actuator, the spring returns the piston and actuator into it’s up position, and the ball is returned to it’s resting position, sealing the chamber and preventing the liquid product from flowing back down into the bottle. This initial cycle is called “priming”. When the user presses down on the actuator again, the product that is already in the chamber will be drawn from the chamber, through the stem and actuator, and dispense out of the pump and onto the consumer’s hand. If the pump has a bigger chamber (common for high output pumps), it may require additional priming before the product will be dispensed through the actuator.
Lotion Pump Output
The output of a plastic lotion pump is often measured in cc (or ml). Commonly in the range of 0.5 to 4cc, with some larger pumps with bigger chambers and longer piston/spring components having output up to 8cc. Many manufacturers have multiple output options for each of their lotion pump offerings, giving the product marketer full control of dosage.
