Foam Pump Bottle Use

As the China Foam Pump(KEXON) is used, there is residual liquid on the screen. If the pump is not used frequently, that soap liquid can dry, creating a film on the screen which can ultimately clog the screen making the pump hard to use.

The pump mechanism has a small amount of lubricant in order to keep the pump moving smoothly. While I haven't been able to get confirmation from the manufacturer, it seems that some soaps eat away at the lubricant, reducing its effectiveness over time. So far I have not been able to identify why the lubricant is affected by some soaps and not others.

Troubleshooting

If you have trouble with the pump, particularly the pump "sticking" and not popping back up, check the following things:

Is the soap too thick?

This is a common problem with the pumps. To work in the foam pump bottles the liquid should be water-thin. If it is too thick, the pump won't work properly and/or can be permanently damaged. To resolve, increase the dilution rate or use a different soap.

Is there liquid in the air chamber?

You should see it inside the chamber below the pump. If so, turn it upside down and pump a few times which should get the water out of the air chamber. If that doesn't work (and if you are brave) take the pump apart, clean it completely, dry thoroughly and reassemble.
