Geotech Bladder Pump
The Geotech Geocontrol PRO™ is a compact, portable controller designed to operate bladder pumps for low-flow groundwater sampling and well purging. Featuring an integrated high-performance air compressor, the Geocontrol PRO eliminates the need for bulky external compressors or compressed gas cylinders, providing a safe and efficient solution for environmental groundwater monitoring.
Capable of operating bladder pumps at depths of up to 55 metres (180 feet), the Geocontrol PRO delivers precise, repeatable control for obtaining representative groundwater samples in accordance with recognised low-flow sampling practices.
Reliable Low-Flow Sampling
The integrated mini-compressor and adjustable fill and discharge timers provide accurate control over pump cycling, allowing users to optimise flow rates for both well purging and low-flow sampling. Compatible with portable, dedicated, and most air-operated bladder pumps, the controller offers exceptional flexibility across a wide range of monitoring applications.
Designed for Field Use
Weighing just 4 kg (9 lb), the Geocontrol PRO is easy to transport and operates directly from a 12 V DC power source. Push/pull airline fittings simplify tubing changes, while built-in reverse polarity protection enhances reliability during field operation. Optional accessories, including rechargeable battery packs, carrying cases, and drawdown control modules, further improve usability.
