Abstract
A manually operated dispensing pump has dual pump mechanisms, one pump being operable in a normal upright position and the other pump being operable when the apparatus is inverted. The dual pumps are fed from the same storage vessel for the media to be pumped. A preferred embodiment arranges the dual pumps successively along the same axis, each having suction ports and valves operable to enable the respective pump when the apparatus is correctly positioned and to seal off the pump when the other pump is enabled.
