First 12 Volt Submersible Centrifugal Pump to fit into a 1" ID Well

The Engineered Plastic 12 volt submersible centrifugal Storm® 50 pump is capable of pumping up to 50 feet from ground level (DTW)* by simply connecting the Storm® 50 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 Storm® 50 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 Storm® 50 can operate under harsh conditions with higher turbidity.

  • The Storm® 50 can run continuously in water without the need for a cool down!

  • The Storm® 50 has a 150 hour motor life!

  • The Storm 50® has a sleek outside that minimizes well hang-ups.

  • The Storm 50® is a very reliable and economical pump that provides a great bang for your buck!


This pump is not engineered to be dedicated in liquid 24 hours a day.
