Forget about having to purge multiple well volumes before sampling, because with low-flow purging technology you can obtain accurate, precise samples with a reduction in purge volumes of up to 95 percent. Low-flow samples bypass stagnant, contaminated water in the well casing and exhibit reduced turbidity, minimized degassing and volatilization. In most cases, you won’t have to filter samples before analysis. Low-flow sampling is approved in almost every state and EPA region. With the Sample Pro Consultant Kit, we offer a complete system for low-flow ground-water sampling specifically engineered for rugged field duty. The heart of the Kit is the MP10 MicroPurge Basics controller that revolutionizes sample pump flow control by making it simple, stable and repeatable. No overshooting, no flow rate fluctuation to disturb the well. An ID mode lets you recall a flow setting for the next sampling round. The Sample Pro pump was designed specifically for portable low-flow sampling. De-contamination is done with quick-change, one-piece disposable bladders.
The QED MP20D flow cell is engineered to allow the sensing probes to make rapid, accurate responses to changes in purge water parameters. The flow cell is 100% transparent for ease of observation. The low-volume, fast-response cell couples to the sonde with a quick, bayonet attachment, and can be used in either a horizontal or vertical position. The incoming flow is directed in a tangential path around the flow cell to provide fast, thorough mixing with no 'dead spots' that could affect the accuracy of purge parameter measurements. Bubbles in the flow stream are vented out of the cell and away from the probe purge water analysis. The multiparameter probe has a special sensor with built-in stirring for highly stable dissolved oxygen readings. All sensors are easy to calibrate and the unique pH preferencce electrode is fully field-serviceable, a huge advantage in keeping field work on track as well as reducing pH probe replacement costs.
The 3020 Compressor is a useful option for low-flow sampling of wells at depths to 100 feet. It runs on a 12 volt DC electrical supply, and can be connected to your vehicle's battery with the supplied cables, or driven by a separate power source.
At just 15x11x6-1/2'' and 15 pounds, it offers an extremely convenient, portable pneumatic power choice for many sampling systems.
Available Models: MP10, MP10H and MP10UH

Well Wizard pumps for MicroPurge sampling systems come in an unsurpassed range of sizes, materials, and capabilities, including models for deep wells, narrow or obstructed casings, and small-volume pumps for low-yield wells. Together with MicroPurge controllers, flow cells, and accessories, they create the most reliable, cost-effective low-flow 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 50,000 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 over nearly 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.
Pneumatic bladder pumps operate with a unique, gentle action ideal for low-flow sampling. Timed on/off cycles of compressed air alternately squeeze the flexible bladder to displace water out of the pump, and release it to allow the pump to refill by submergence, without creating any disturbance that could affect sample chemistry. Bladder pumps run easily at low rates for extended times, without the problems of other devices.
The bladder prevents contact between the pump drive air and the sample, and the downwell equipment is permanently dedicated to each well, so both samples and the well are protected from disturbance or the danger of cross-well contamination.
Well Wizard bladder pumps are part of the complete MicroPurge equipment system for low flow sampling, engineered for easy installation and use. QED application specialists will help specify the most effective, economical pumps and accessories for your site.
Each pump is cleaned and laboratory-certified to be free of volatile organic compounds, acid extractable and base neutral contaminants. Your system is preassembled, with tubing cut to length, ready to install.
If desired, installation by OSHA-certified field technicians is available. QED customer support -- with trained local representatives, 24-hour toll-free hotline, and next-day loaners or service turnaround when nee ded -- backs you with unmatched expertise and service.
More MicroPurge dedicated sampling systems and pumps have been chosen since 1982 than all other manufacturers' equipment combined.

This stainless steel Well Wizard dedicated bladder pump is ideal for deep-well applications and can be paired with our MP10H MicroPurge Controller. The Well Wizard pumps have a field-proven design and durability required for long-term dedicated monitoring. They are ideal for low-flow sampling (are EPA-accepted) and widely accepted by regulatory agencies, as well as people in the field. The exclusive PTFE bladder formulation has been rated for more flex life than other bladder materials, and the Well Wizard pumps are issued a 10-year warranty, which speaks to its' reliability.
Cleanup well conditions can be downright hostile: powerful solvents, gasoline and fuel oil, strong acids, caustic bases, corrosive chlorides. That’s why QED makes the Pulse Pump series (our basic gas displacement pumps) in a variety of proven materials that won’t just survive, but will deliver years of trouble-free performance.
Every Pulse Pump model has only two moving parts downwell: high-clearance, self-cleaning ball check valves. This simplicity keeps them working when high solids, viscosity, or chemical attack cause other pumps to clog or breakdown. An external controller is required to control the alternating pressurization and venting cycles for the pump.
The Pulse Pump design is especially suited for sinking hydrocarbons (DNAPL) recovery, which is often complicated by high viscosity and/or extremely aggressive solvents.
Intrinsically safe Pulse Pump systems are fast and easy to install, with no electrical connections at the wellhead.
Flow optimization is simple too; rugged, dependable pumps and controllers (the solar/AC powered C100M and the all-pneumatic L360) deliver reliable operation without needing frequent attention or repair.
Even in the harshest environments, they just keep working - in the most demanding ground water cleanup, leachate collection, and sinking layer recovery applications.
Easier to Disassemble and Clean
The AP4+ was made easier to clean by using 3 bolts to attach the pump inlet and open up the pump. This is easier than having to rotate the inlet multiple turns to unthread it from the center tube inside the pump, especially under field conditions of silt, deposits and coatings. Removing the inlet is also aided by the new, precision ID pump casing, ensuring a more controlled fit. The new pump casing’s smoother internal surface has the added benefit of reducing the rate of buildup of solids and coatings inside in some cases. The Easy Fittings make it a snap to remove the tubing from the pump without cutting, and the float is now easily removed by pulling a clip.
The new AP4+ features upgraded materials for many parts to further extend the service life of the pump and to broaden the range of conditions each model can be used in. All nonmetallic internal parts are now made of PVDF*; this is a high-grade engineering plastic with higher strength at elevated temperatures and extremely broad chemical resistance, including to acidic and oxidizing cleaning agents sometimes used for pump maintenance. All stainless steel parts have been upgraded to 316-grade for improved corrosion resistance.
