Mist Sprayer Pump selection and components

How well do you want your dog to be?

Depending on your product, you can choose the type of atomization that works best for you. Fine mist sprayers deliver shorter, smoother, softer sprays, which are very popular in personal care and cosmetic products. Regular sprayers will dispense longer, tighter, and denser spray patterns.

Components of the sprayer

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

Dust cap

Usually made of clear PP plastic, the cover acts as a dust cover and safety cover to prevent accidental dispensing of the product by the actuator.

Actuator

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

insert

This tiny component is where the liquid flows to create the mist-like pattern and is 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 comes with many different finishes and design options, including but not limited to metal casings.

Gasket

This is what seals the cap 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

The mechanism is actually a combination of many different components, including the piston, valve stem, seal, spring, and housing cover. This is what transfers the product from the bottle to the actuator. Depressing the actuator draws the product up the dip tube, through the piston to the actuator, where the product is expelled from 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, nebulizer dip tubes are thinner and generally curved slightly to allow them to reach the bottom, allowing it to dispense all of the product's contents.
