Treatment Pumps

When the Treatment Pump is in use, first press to discharge the air in the liquid storage chamber, that is, the plastic tube that can absorb water. When the air is exhausted, press the pump head again, because after letting go, the spring in the pump head will return to its original state , then a vacuum will be formed in the liquid storage chamber and a negative pressure will be generated. At this time, the pressure in the container will be consistent with the atmospheric pressure. Then, the pressure in the liquid storage chamber will be small and the pressure in the container will be high. Poor, the atmosphere will press the liquid around the mouth of the liquid storage cavity into the liquid storage cavity, and the liquid foundation will be squeezed out.
