12V Submersible Whale Sampling Pumps

Super Purger & Mini Purger

Fieldtech Solutions is proud to offer the Whale ‘Super Purger’ and ‘Mini Purger’ groundwater pumps for sampling or well development. These 12V electric submersible pumps have long been used throughout the world because they are compact, reliable, and easy to use. Simply attach your tubing, connect to a 12V power source such as a car battery, and you are ready to purge and sample.


  • Only 36mm diameter, ideal for standard 50mm monitoring wells
  • Heavy gauge cable and alligator clips
  • 12V DC operation
  • Lower current draw for more efficient performance
  • Tough plastic construction with PBT impeller
  • Flow rates up to 12 LPM
  • Pumping depths up to 18m with Super Purger, and 12m with the Mini Purger
  • Also available on reel for easy sampling kit (see pic.)
  • Compatible with 1/2″ or 5/8″ BioTubing


The Whale pumps can be ordered on a reel like the above picture so that it makes a tidy kit which protects the pump and cable. The cable is installed onto the reel and fed through the centre for ease of use. The reel comes with a detachable jumper cable, on/off switch and pump scabbard.


Note: If greater than 18m lift is required please call or email for options.

GREEN-DEX™ Keeps All the Performance of N-DEX™ Gloves, and Is Also Eco-Friendly:

Regular nitrile gloves cannot attract enough (if any) microbial activity to begin breaking down the polymer’s molecular structure, thus leaving the process of reclamation to light, heat, mechanical stress and moisture. An innovative and truly groundbreaking characteristic of the EBT additive is the ability to maintain the same physical properties (texture, appearance, chemical protection etc.) as regular nitrile gloves but with the added advantage of being landfill-biodegradable.
