How it works When first placed in a borehole, water will fill the pump as it is submerged. The float will rise to the top of the cylinider. When connected to an air supply the pump will initially empty by pushing water through the discharge line and the float will fall to the position shown in Fig 1. The pump then cycles as follows:- Fig 1: As the pump empties the float sinks to the bottom of the pump cylinder and hits a lever. This triggers the valve mechanism and simultaneously shuts off the air supply inlet and opens the air exhaust vent. Once the air starts to vent, the hydrostatic pressure of water will push open the valve in the water inlet allowing the pump to fill. Air will continue to vent as water enters and the float rises in the cylinder. Fig 2: When the float reaches the top of the pump cylinder, it hits a lever which triggers the valve mechanism. This simultaneously closes the air exhaust valve and opens the air supply inlet valve. The incoming pressure of air then closes the valve in the water inlet and forces water into the cischarge tube. Fig 3: As the water is discharged, the float sinks until it reaches the lower lever arm. At this point the cycle is repeated (Fig 1)  |
