Over 25 years ago, QED installed the nation’s first dedicated bladder pump groundwater sampling system. Since then, we have led the industry in producing the most accurate, cost-effective ways to collect groundwater samples. More Well Wizard® bladder pumps are operating in monitoring wells worldwide than all other dedicated sampling pumps combined. Years of QED efforts to promote low-flow sampling, plus the introduction of MicroPurge® control equipment, have helped these methods become widely accepted practice as the ground water monitoring community looks for higher sample accuracy and lower costs. QED's state-of-art groundwater sampling product line includes portable and dedicated pumps, control modules, flow cells, water & drawdown meters, inline filters and more!

Well Wizard® Dedicated Bladder Pumps
Over 75,000 Well Wizard bladder pumps are in use – more than all other brands and types of dedicated ground water samplers combined.

• The most precise, reliable sampling pumps, with EPA-accepted low-flow sampling accuracy.
• Models for every well -- low yield, short water column, depths to 1,000 feet (304.8m), well I.D. down to 1.25" (31.75 mm).
• Exclusive PTFE bladder formulation rated for years more flex life than other bladder materials.
• Proven reliability since 1982, with the industry's first standard 10-year warranty.
• Sample Pro® Portable Bladder Pumps
• Designed to bring the advantages of low-flow sampling to sites where samples are taken with portable pumps. Exclusive twist-apart design makes it easy to pull off the disposable bladder between wells -- no tools required.
• The only portable pumps designed for low-flow sampling, with EPA-accepted accuracy.
• Available in two sizes; 1.75" (44.5mm) for 2" (50mm) or larger monitoring wells, and 0.75" for 3/4" (19mm) monitoring wells or direct-push applications.
• Quick 1/4 turn disassembly with no tools means simple, fast and complete field cleaning. Disposable bladders and push-in tubing replace in seconds, speeding you on to the next well.
• Solid stainless steel construction is truly durable, with no motors, bearings, or impellers to go bad. Output pressure is strong and controllable.
