There are several reasons for inconsistent evacuation:
For initial use, the pump must be primed anywhere from 5-15 times. As there is no dip tube, this will create a suction to allow product to dispense.
If there is an empty space/no product between the top of the bulk and the base of the pump, the product will not evacuate. You will need to prime or continue pumping until there is no empty space between the top of bulk and the base of the pump in order to create a vacuum for the product to dispense properly.
Another possible cause for the dispensing issue will be hidden air pockets in the product itself.
This can happen if the product is stored on the side, not used consistently or if the product is tossed around in a hand bag. In order for proper, consistent evacuation, the pump will need to be re-primed to make contact with product and for dispensing to occur. A gentle tapping of the bottle onto a hard surface may also help remove air pockets. The pump must be screwed on tightly.
