Bladder Pump Controller 300 PSI

The Geotech Bladder Pump (BP) Controller (300 PSI) utilises advanced electronic logic to control gentle, low-flow sampling.


Simple to use, accurate microprocessor controlled FILL/DISCHARGE timers are utilised to recreate expert techniques for low-flow sampling. The BP Controllers are equipped with high-pressure valves and fine resolution regulators that can deliver in remote and deep sampling applications. BP Controllers connect to any bladder pump system with the use of simple quick-connect adapters.

The Bladder Pump Controller is also available in 500 PSI.
