DC4.0V mini water pump for liquid alcohol sprayer

DC Diaphragm Water Pump is a special type of pump with self-priming ability, which can extract liquids from water tanks or other lower containers. It is widely used in many fields, such as irrigation, cleaning, fountains, medical and beauty industries, etc. In automatic soap dispensers, micro diaphragm water pumps also play an important role.

The automatic sensing soap dispenser is an intelligent hand soap dispensing device that can automatically sense and output an appropriate amount of hand soap according to the user's hand movements. In this process, the micro diaphragm water pump plays a crucial role. When the user places their hand in the sensing area, the sensor will immediately detect and send a signal to the micro diaphragm water pump.

After receiving the signal, the micro pump will quickly start and generate a certain pressure to extract the hand soap from the storage tank. Then, the hand sanitizer is pressurized by a pump and transported through a pipeline to the dispenser. In the dispenser, hand sanitizer will be further processed and evenly distributed into the nozzle. Finally, when the user leaves the sensing area, the sensor will send another signal to the micro diaphragm water pump to stop working.

Why are some micro diaphragm water pumps only suitable for soap dispensers with alcohol type liquids? What about the soap dispenser that cannot be used for foam liquid?

Some Micro Diaphragm Pumps can only be used for the soap dispenser of alcohol type liquid, but not for the soap dispenser of foam type liquid, which is mainly determined by its structure and design

Micro diaphragm water pumps are usually composed of components such as diaphragm, air valve, liquid valve, and pump body. For alcohol type liquid soap dispensers, due to the small surface tension of alcohol itself, it can flow smoothly inside the pump body, and the Mini Water Pump can effectively suck in and discharge the liquid.

For the soap dispenser with foam liquid, because the liquid contains a large number of bubbles, which makes the liquid have a large surface tension, the diaphragm pump may be blocked by bubbles when inhaling the liquid, resulting in the failure of normal flow inside the pump body, thus affecting the working effect of the pump.

Technical Specification

What is the difference between the structure of the Micro diaphragm pump for alcohol type soap dispenser and that of the pump for foam type soap dispenser?

For soap dispensers suitable for alcohol types, the design of micro diaphragm water pumps will pay more attention to the solubility and volatility of alcohol. In order to better transmit alcohol, the internal structure of the pump needs to be able to withstand the corrosion of alcohol while ensuring efficient transmission efficiency. In addition, due to the high volatility of alcohol, the design of the pump chamber also needs to consider this to prevent excessive or insufficient internal pressure.

For the soap dispenser used for foam type, the design of Self Priming Micro Water Pump will pay more attention to the transmission effect and stability of foam. It usually has a special pump head design, which can transform liquid soap into foam to provide better cleaning effect

Can the lifespan of a micro diaphragm water pump meet the requirements of an automatic soap dispenser?

The lifespan of a DC Water Pump refers to the number of cycles it can operate normally. For automatic soap dispensers, multiple cycles are usually required to complete one use, so the lifespan of the water pump needs to be able to meet the requirements of frequent use.
