Well Wizard pumps for MicroPurge low flow groundwater sampling systems come in an unsurpassed range of sizes, materials, and capabilities, including models for deep sampling wells, narrow or obstructed casings, and small-volume pumps for low-yield monitoring wells. Together with MicroPurge controllers, flow cells, and accessories, they create the most reliable, cost-effective low-flow groundwater sampling system available.

Field proven pump designs and exclusive, high performance PTFE bladder formulation offer the reliability critical to long-term monitoring. QED was first in the industry with a standard 10-year sampling pump warranty – "no-loopholes" protection that covers the entire pump, including the bladder.

Bladder pumps, EPA-accepted for low-flow sampling, have been shown to deliver superior sample accuracy and precision in dozens of independent studies. Over 75,000 Well Wizard bladder pumps are in use – more than all other brands and types of dedicated ground water samplers combined.

Well Wizard pumps are built for reliability, with refinements perfected for more than 20 years of continuous engineering and improvement – extra value you won't find in any other bladder pump. One example: stainless steel in Well Wizard pumps is electropolished to passivate the surface, delivering years more corrosion resistance than competitors' models.
