4. Pump submergence is defined as the height of the static water column above the top of the pump In wells in which this water column height is 5 feet or less the pump is considered to be in a low submergence application QED sampling bladder pumps fill by hydrostatic pressure As the inside of the pump s bladder fills with water the bladder expands This filling and expanding of the bladder is referred to as the refill half of the pump cycle When air pressure is applied to the outside of the bladder the bladder is squeezed forcing the water up the discharge tubing This is referred to as the discharge half of the pump cycle In low submergence applications there is less water pres sure available to expand the bladder during the refill This can result in a smaller volume of water being pumped with each pump cycle because the bladder may not fully expand As a result of the lower volume per cycle more time will be required to bring the water to the surface An easy way to verify that the pump is working prior to the water reaching the surface is to submerge the pump s discharge tubing in a beaker of water Each time the pump goes into discharge air in the discharge tubing which is displaced as the water level in the tubing rises can be seen as air bubbles coming from the end of the tubing To optimize the pumping rate the refill time should be set long enough to achieve the maximum volume of air bubbles on each pump cycle and the dis
