Geotech Reel E-Z®

The Geotech Reel E-Z® is a compact system designed to provide a convenient way to store and operate a Grundfos® MP1 2" Pump. When used with the Happy Hose!® (cable, tubing, and safety cable bonded together) the system easily installs the pump in the well, locks it in place and allows for easy take up and cleaning without cable entanglement. The roller guide protects the cable from well damage and the Reel E-Z can accommodate both above, and below-grade well applications.


  • Lightweight aluminum

  • One-person portability

  • 250' (76.2m) Happy Hose!® capacity

  • Easy decontamination

  • Cable guide for Happy Hose!®

  • Installs vertically or horizontally

  • Locking holster for pump storage

  • Removable reel handle

  • Can be shipped UPS.

    vehicle battery

Grundfos Redi-Flo2.jpg

Grundfos Redi-Flo2

The Grundfos Redi-Flo2® Electrical Submersible Pump provides smooth, uninterrupted water flow during groundwater sampling or conducting aquifer tests to depths down to 280 ft. (85m). Both high flow rates needed for purging and low flows recommended for sampling are achieved with the same pump. 
Designed for long-term reliability in dedicated monitoring wells, the Redi-Flo2® provides optimal sample quality with either traditional purging prior to sampling or low draw-down passive sampling when operated with the Redi-Flo VFD (Variable Frequency Drive).


  • Chemically inert materials Maximum sample integrity and easy decontamination

  • 1.8 inch (4.6cm) diameter Easy access into 2" (5cm) or larger wells

  • Flow rates range from 8 GPM (30 LPM) to as little as 100ml ⁄min Controlled with the simple push of a button

  • Low velocities and agitation Ideal for sampling and purging

  • Portable solid state converter Eliminates the need for control valves

  • Continuous flow Ensures a cleaner, simpler sample catch

  • Dedicated or Portable configurations available

Surface Water Sampling

Long Handle Dipper.jpg

Bel-Art Long-Handled Dipper, 3’

Used for easy sampling from tanks, vats, lakes, etc., these high-density, polyethylene dippers will not contaminate solutions or corrode. 1-1/8” (29 mm) Diameter handle is welded to the rigid 16 oz. (500 ml) bowl at a 45° angle. Available in 3’, 6’, or 12’ lengths. 12’L Dipper features a two-piece, screw-together handle.


Wastewater/STORM WATER Sampling System

This versatile sampling system allows you to set the sampling mode for each of two pumps and bottles individually. Because it is actually two samplers in one, consisting of two intake tubes, two sampling pumps, and two one-gallon sample bottles, any possibility of cross-contamination between the samples is eliminated. You can obtain two individual time-weighted or flow-proportional composite samples, two full-bottle discrete (grab) samples, or a full-bottle discrete (grab) sample in one bottle and a time-weighted or flow-proportional composite sample in the other. When taking two composite samples, you can even adjust sample size settings for each pump. The sampler can be easily set up and installed in any stormwater channel to take and store physical water samples throughout a storm event. Included are a rainproof lockable carrying enclosure, two one-gallon polyethylene sample bottles, two peristaltic sampling pumps, a control panel-enclosed logic timer/controller, two 15’ reinforced PVC sample pickup hoses with removable debris strainers, a 5 AH rechargeable gel cell battery, and a battery charger. The Stormwater Kit (sold separately) includes a rain sensor, flow sensor, and an auto-drain rain gauge.
