l How to judge a good quality lotion pump?

1. The glass ball or steel ball under the spring. the sealing is very important, relates to the strength of the liquid to rush up. If there is leakage, there will be some liquid leakage into the bottle when we pressed, and affect the effect of liquid pumping out.

2. The sealing ring on the upper end of the valve body. If there is leakage here, when the pressure handle is released, the bottom of the liquid pumping force is reduced, resulting in only little of liquid stored in the valve body, will also affect the effect of pumping out.

3. The matching of pressure handle and the valve core. If here is loose or leak, there will be a certain resistance when the liquid rushes to the nozzle, the liquid will flow back, if the leakage here will also affect the effect of pumping out.

4. Nozzle design, nozzle design is directly related to the effect of spray. A well-designed nozzle of the lotion pump can avoid a leak when no use.

These are the tests we do before we shipping out of the warehouse to our customers, and also routine inspection of appearance to ensure good quality.
