Geotech Environmental Control Module (GECM) Pneumatic Pump Controller.

More pneumatic well pump control and productivity with less effort and equipment.

Geotech Environmental Control Module Pneumatic Pump Controller


The Geotech Environmental Control Module (GECM) Pneumatic Pump Controller is a unique pneumatic pump control system used for operating most downwell pneumatic remediation or sampling pumps. The power used to run the GECM Pneumatic Pump Controller can be generated on-site by solar panels or from an AC electrical source. When the system is properly outfitted, it can handle pressures up to 150 PSI (10.3 bar). Maximum depth to fluid pumping capability is 320 feet (100m) below ground surface. Tubing size requirements will vary depending on the pump type and the length of tubing runs. Geotech can assist in determining these parameters to meet your specific site installation requirements.

The GECM Pneumatic Pump Controller greatly reduces total fluid pump maintenance by simplifying the downwell components and placing the timing and control mechanisms at the surface.

GECM AC Powered System

The system is ideally suited for use with Geotech's Reclaimer pumps. Reclaimer pumps can be purchased in a variety of lengths and intake configurations to meet your site's needs.

The standard GECM Pneumatic Pump Controller can be configured for either AC power or a 12VDC battery that is charged with an attached solar panel. Multiple channel controls can be implemented in areas where there are multiple recovery wells within close. Up to eight separate wells can be operated per controller. Clean, dry air is recommended.


Ease of Deployment
The GECM Pneumatic Pump Controller can reduce overall project costs and dramatically improve deployment as follows:

  • Flexible, easy-to-install power supply options.
  • Optional simple and safe low voltage solar power systems can be installed with minimal experience.
  • Remote operability can reduce overall costs of system installation and maintenance.
  • Reduce down well component complexity by placing the timing and control mechanisms on the surface.

GECM Operation
The GECM pneumatic pump controller has an integrated programmable cycle timer for controlling the individual pump times and the time between each cycle. Optimal timer settings will vary with site configuration, seasonal water table variability, process treatment requirements and various pump specifications.

On multiple channel GECM systems, pressure and delay cycles are set individually per well. This accommodates recharge and recovery rates unique to individual wells at the same site. A variety of timer setups can be implemented to maximize recovery. For example; different wells can be pumped more or less often than the others to maximize recovery. The programming prioritizes the pumps so only one pump is operating at a time.

The GECM controller has several feedback data recording mechanisms that can be used to gauge effectiveness of the remediation system. Two cycle counter screens are available, one records the total lifetime cycles of the controller, the other counter is resettable by the user for monitoring purposes.


These cycle counts can be compared with total recovered fluid to determine how much fluid is being recovered per pump cycle. There is also a runtime clock which only increments when the battery is charged or the unit is receiving AC power and when the system is operating. This clock can be compared with actual recorded deployment time to determine if more solar panels are required to keep the system up and running or if power outages are occurring on the site.

Geotech offers training on the proper installation and operation of your GECM system at it's Denver, Colorado manufacturing headquarters.
