Abstract: A pump constructed entirely from a polymeric material is described. The pump includes an internal sealing plug and adaptable insert coupled to a resilient bellows structure. The plug includes a keyed feature that allows for selective sealing at the lower end of the pump chamber depending upon the rotational alignment of the actuator head and closure, owing to stopper mechanisms appropriately positioned along the peripheral interfacing surfaces of these components.
