The liquid pump of an automatic soap dispenser is one of the core components that ensures precise and controllable release of soap liquid.

Pump type

The liquid pump used in an automatic soap dispenser is usually a plunger pump or a gear pump, and both types have their own advantages.

Piston pump: The plunger pump moves the plunger up and down in the cylinder, thereby changing the volume of the pump chamber and realizing the suction and discharge of liquid. It typically has a higher pressure output and is suitable for scenarios where a precise amount of soap needs to be released quickly.

Gear Pump: A gear pump uses one or more pairs of gears to move a liquid. It has a relatively simple design and smooth operation, making it suitable for applications requiring a more even release of soap.

flow control

Liquid pumps must be designed to accurately control flow, ensuring that the amount of soap liquid released is precisely measured each time. This is usually achieved by adjusting the operating speed of the pump or using a regulated pump design. This helps avoid waste and ensure hygiene standards while delivering the handwashing experience users expect.

material selection

The materials in which liquid pumps are constructed need to be chemically stable to prevent adverse reactions with liquid soap. Common pump materials include stainless steel, plastic (such as PP, PE), etc. Especially for automatic soap dispensers used in the medical or food industries, the choice of materials is even more critical and needs to comply with relevant hygiene and safety standards.

Wear and corrosion resistance

Since liquid pumps operate at relatively high frequencies, especially in public places, the wear and corrosion resistance of the pump are key considerations. Liquid pump materials and coatings need to be sufficiently durable to ensure reliable operation over a long period of time.

Noiseless design

To improve user experience, the liquid pump of an automatic soap dispenser usually needs to be designed to be silent to reduce the noise level during operation. This is particularly important for use in quiet environments, especially in medical or office settings.

energy-saving design

The energy-efficient design of the liquid pump helps reduce energy consumption, extend battery life, or reduce dependence on external power sources. This may include the use of low-power motors, intelligent energy management systems, etc.

Leak-proof design

To prevent leakage of soap liquid, liquid pumps usually have sophisticated valve and seal designs. This ensures that no soap liquid will leak out when the liquid pump is not working, maintaining a clean environment around the equipment.
