Free up your Time! Free Up Your Mind!

Proactive® Smart AC to 12 Volt DC Transformer with Liquid Detection (LD) Sensor and Tank Float  Switch Autonomous Pump Control Technology!


Set it and Forget it!

Abyss Transformer #4 provides Abyss® pump line series double the purge flow rate,

Constant Voltage Boosting Technology (CVBT) and autonomous pump operation incorporating Liquid Detection Sensor (LD), Multiple Settings Timer, and Tank Float Switch Technologies

















The Abyss Transformer #4 is compatible with the

Proactive Environmental Products® pumps listed below:

Abyss® and Abyss® Slimline pumps


If you plan to power the Proactive® brand pumps listed above with other means of energy, please contact us to discuss the full line of Proactive® Autonomous Pump Control System options for: Solar, 12-volt battery / 12-volt battery bank, or gas generator.


Applications of the Abyss Transformer #4: When using the Abyss® series pump line include,

but not limited to: 24/7 stationed applications in groundwater, surface water, vaults or the like for: Pump Tests, Long or Short Term Purge, Remediation, Liquid Transfer, Groundwater and Surface Water Monitoring, Hydrocarbon Recovery [LNAPL/DNAPL]






Abyss Transformer #4 provides flexible product features. If you appreciate options (the good news all options are included with the product), you will be pleased to know you can select from any or all of the Abyss Transformer #4 features!

Option #1: LD Sensor Detection and Dry Run Detection Feature

The LD sensor detects (conductive) liquid*. The pump will run as long as the LD sensor is suspended in liquid. When liquid draws down below the LD sensor, the dry run sensor takes over and transmits a signal to the Abyss Transformer #4 to shut-off the pump. As liquid level rises again covering the LD sensor, the LD sensor takes over and transmits a signal to the Abyss Transformer #4 to turn on the pump. This cycle continues automatically.


Option #2: Tank Float Switch Feature

This feature prevents tank over-fill and provides control over the desired total volume of liquid that enters the tank. The tank float switch detects the full-set point (assigned upon tank float switch deployment) and transmits a signal to the Abyss Transformer #4 to shut-off the pump. The pump remains off until the tank reservoir drops triggering the tank float switch to transmit a signal to the Abyss Transformer #4 to turn on the pump again. This cycle continues automatically.


Option #3: Multiple Settings Timer

The Abyss Transformer #4 timer provides multiple intervals on/off settings within a 24 hour period delivering total autonomous pump run-time control.  This cycle continues automatically.


Option #4: Incorporate all Autonomous Features

The LD and Dry Run Detection Sensors, Tank Float Sensor Switch and Multiple Settings Timer proving the ultimate experience in autonomous pump control system available!
