These are designed to screw straight onto the top of our 5L cleaning chemicalsbottles, these all have a opening diameter of 38mm.
Each full pump will dispense 30mL of liquid. They are designed to pump quite thick liquids, like hand soaps. As well as thin, water like liquids with ease.
These are fantastic for an easy and no mess dispensing of our cleaning products into smaller spray bottles. Many of the concentrates only require a few pumps of liquid, then can be topped up with water to get the right concentrations.
