Identifying the Parts of a Soap Dispenser Pump from Cosmetic Treatment Pumps

A simple soap dispenser pump consists of several components that work together to deliver precise amounts of liquid. These components include:

closure: the part of the pump that is secured to the neck of the bottle, usually having a smooth or ribbed surface

Actuator: This is the top of the pump, also known as the pump head, that presses down to dispense product

Outer Gasket: Fits inside the lid, usually made of plastic or rubber, responsible for preventing the product from leaking

Housing: The main pump assembly that holds the pump assembly in place and delivers fluid to the actuator

Dip Tube: the visible tube that extends from the housing to the bottom of the container and is used to carry liquid for dispensing

Internal components: various parts including springs, balls, pistons, and/or rods that help move product from the container to the actuator

Mechanics of Soap Pumps

Soap pumps rely on the parts of the bottle and the suction of the air to draw the liquid up and against the laws of gravity.

Every time you press or activate the actuator, the piston applies pressure to the spring and moves the ball up, taking some of the soap product with it.

When you release the actuator, the piston and spring return to their rest positions, sealing the housing chamber to stop liquid from flowing back into the bottle.

Dispense Options

Actuators are designed to meet different output needs. Product output is measured in milliliters (ml) or cubic centimeters (cc).

These measurements are important for proper dosage, which can range from as little as 0.5 cc to as large as 8 cc. Depending on the type of product you are bottling, you can order the type of pump output that best suits your needs

How to choose a soap dispenser pump?

Material composition: The quality of raw materials determines the durability of the dispenser. Besides the usual polypropylene plastic, steel and glass materials are also used.

Designs and colors come late, always making sure that the material composition is the best in the market.

The durability of steel, the cost-effectiveness of glass/ceramic. This will directly depend on whether your use is for commercial or personal use.
Tube Length: The diameter of the tube length is proportional to the increase in viscosity of the liquid. So when you are choosing a lotion pump, choose wisely and keep the ratio of viscosity to tube length in mind.
