Bladder Pump Operation
Bladder Pumps are widely used in groundwater sampling and require a compressed air source and a controller to operate.
The Compressor forces air down the tubing to the pump where it squeezes the bladder. When the bladder is squeezed water in the pump is pushed up the discharge tubing. When the pressure is released or vented, the bladder returns to its original shape and water from the well enters the pump.
The Controller cycles the air between pressure and venting to alternately squeeze and relax the bladder. This cycling creates a pumping action as the pump is filled then the water is pushed up the tubing in increments.
