The Engineered Plastic 12-volt submersible centrifugal Tempest/Twister® pump is capable of pumping up to 60 feet from ground level (DTW)* by simply connecting the Tempest/Twister® to a 12 volt deep cycle battery. Its reliable design is perfect for continuous sampling and purging of groundwater wells and Low Flow Sampling (Fractional Flow®).

 

The 12 Volt Tempest/Twister® is ideal for low flow sampling (Fractional Flow®) in conjunction with Proactive Environmental Products Low Flow Sampling Controller. Low flow sample all the way down to 40 mLs per minute. To achieve even a lower flow.... simply add the Low Flow Sampling Control Valve in conjunction with the Low Flow Sampling controller to achieve flow rates of 10 mLs per minute or less!

 

Simplify and Expedite Your Next Sampling Event!

• The Tempest/Twister® can operate under harsh conditions with higher turbidity.
