    Combined Compressor & Controller

    The Geocontrol Pro is a lightweight bladder pump Controller with a built-in high performance air Compressor. Use with a 12 Volt battery and Bladder Pump to purge or sample monitoring wells to depths of 180 feet. The combined functions and easy to set control rates make the Geocontrol Pro extremely easy, consistent and reliable in the field. Use with any bladder pump and tubing adapters.

    Controller Only

    Geocontrol 2 is a bladder pump Controller for use with a separate, external compressor or compressed nitrogen tank to operate a bladder pump system. It utilizes advanced electronic logic to control both high rate purging and gentle low flow sampling. Simple to use, accurate, microprocessor controlled on/off timers are utilized to recreate expert techniques for low-flow sampling. The Geocontrol 2 high-pressure solenoid activated valve delivers even in the deepest sampling applications.

    The Geocontrol 2 can be used with any bladder pump and compressor, with simple quick-connect tubing adapters.

    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.
