Components of a spray pump from Mist Sprayer Pumps factory

These are the components that allow the fine mist sprayer to turn the liquid stream into mist:

Dust cap
The cap is usually made of clear PP plastic and acts as a dust cover and safety cover to prevent the actuator from accidentally dispensing product.

Actuator
This is how you press to dispense the product, and unlike the lotion pump actuator, it has internal components to create a specific atomization pattern of the product. The consumer pushes down to squirt the product from the bottle. Some actuators also feature locking to prevent accidental dispensing.

insert
This tiny part is where the liquid flows, creating a mist-like pattern and mounted on the outside of the actuator. This is where the product leaves the sprayer.

closure
The cap holds the entire assembly together and secures it to the bottle. It is usually made of PP plastic and has many different finishes and design options, including but not limited to metal casings.

Gasket
That's why the cap is sealed on the bottle to prevent leakage. Different products and chemistries require different material choices, so this is the most important part of testing to ensure compatibility.

mechanism
This mechanism actually combines many different components into one, including the piston, valve stem, seal, spring, and housing cover. This is why the product is transferred from the bottle to the actuator. Depressing the actuator will pull the product out of the dip tube, through the piston towards the actuator, and from there through the insert.

dip tube
This is the long plastic tube that goes into the sprayer from the bottom of the bottle. Unlike thicker lotion pump dip tubes, sprayer dip tubes are thinner and usually bend slightly to reach the bottom so that all of the product's contents can be dispensed.
