The Dispensing Process:
When you press the pump, you create pressure.
This pressure forces the piston at the bottom to move upwards.
The piston pushes against the inner bag, forcing the product up and out through the nozzle.
As the product is dispensed, the inner bag collapses, and the piston takes its place, ensuring no air is ever drawn back in.
This is fundamentally different from a standard pump, which sucks air in to replace the product used, leading to oxidation and contamination.
