Visual Breakdown of the Mechanism

• Standard Pump (Internal Core): The actuator (the part you press) sits directly on top of a hidden inner stem. The connection to the dip tube is not visible.

• This Pump (External Pump Core): The actuator sits on top of a visible, often thicker, outer stem. This stem is the "external core" and is directly connected to the piston and dip tube. When you press down, the entire external stem moves.
