BP Controller 500

The simple-to-use Bladder Pump (BP) Controller 300 utilizes accurate microprocessor-controlled fill/discharge timers to sustain true low-flow sampling techniques. Both Controllers are equipped with high-pressure valves and fine resolution regulators that can perform in deep-well applications.

The BP Controller universally connects to any bladder pump system using simple quick-connect adapters. The BP 300 controller can also operate two bladder pumps simultaneously with an optional airline splitter.
