Electric Submersible Pumps for
Total Fluid & Dissolved Phase Hydrocarbons

Electric submersible pumps are the groundwater extraction pumps usually used at contaminated sites. In lower flow-rate applications, alternative pumps such as pneumatic pumps are also used.

Pump materials are compatible with the contaminants present at most sites. The pumps are constructed of stainless steel, and the motor leads, seals, and bearings are made of materials that are compatible with the site contaminants.

Let Geotech remediation pump experts help you configure the best pump for your site conditions and goals.

Grundfos Redi-Flo3™ SQE-NE Environmental Pumps

Grundfos Redi-Flo3

Redi-Flo3 pumps incorporate a totally new motor design. With the use of permanent-magnet technology within the motor, Redi-Flo3 pumps deliver unmatched performance. The combination of permanent-magnet motors and Grundfos' own micro frequency converter, we are now able to communicate with the pump in ways never before possible. Just a few of the features that come out of this combination are constant level control, soft-start and integrated dry-run protection. These are just a few of the many features that Redi-Flo3 pumps can offer.

Redi-Flo3 pumps are suitable for both continuous and intermittent operation for a variety of environmental applications including:

  • Remediation
  • Pollution Recovery
  • Leachate Recovery
  • Dewatering
  • Tank Applications

Geotech GeoShield Cooling Shrouds

Geotech GeoShield Cooling Shrouds

GeoShield Cooling Shrouds encapsulate electric submersible pumps to protect them against overheating and allows for easy installation in horizontal or vertical wells. The inside diameter of the GeoShield Shroud is slighter larger than the motor housing, forcing water past the motor to displace heat. The outer-material provides a smooth minimal-contact surface making installation easy. Large intake ports allow for high-efficiency flow while an internal mesh screen guards against debris entering the pump intake.

  • Made to Order – Can accommodate most electric submersible pump brands or models.
  • Tough Materials - HDPE designed for demanding environments
  • Rounded Edge – Reduces surface tension and friction
  • Serviceable – Removable protective mesh screen strainer
  • Lifetime Warranty
  • Made in USA
  • Optional – Stainless steel, PVC, and wheeled SS shrouds available
