Panacea: Groundwater Sampling Pumps
The solution to the toughest groundwater sampling challenges
BESST’s Panacea Pumps are unmatched in reliability and versatility, offering the solution to whatever challenge you might be facing in groundwater sampling.
- Deep water
- Narrow Wells
- Large Purge Volume
- Low submergence
- Crooked wells
- High gas consumption
- Slow Recharge
- Corrosive environments
- Extreme temperatures
The pump is powered by inert gas or air, meaning no more risk of malfunctioning from overheating motors. The two-valve lift system, when used in ratchet mode, does not allow the gas to contact the sample water. This pump also enables a gentle discharge of the sample, eliminating the need for fragile and unreliable bladders. Panacea Pumps are available in a variety of sizes and materials. The miniaturized P100 and P125 are ideal for narrow or obstructed wells where clearance is an issue. The P200 is designed for wells 2” and larger, and takes advantage of the additional space with a 200 mL chamber to boost purge and sample volume. All Panacea Pumps are available in 316 stainless steel, for increased depth capability up to 3000 Ft. BGS as well as resistance to corrosive or extreme environments.
Benefits to using the Panacea pump include:
- No motor or bladder
- Deployed in wells as small as 1”
- Volume Booster technology for low submergence and deep first water
- Customizable compression fittings for different tubing (standard 1/4″ connections)
- Delrin, 316 Stainless Steel or PVC construction
- Includes hook or port for support cables
- Customizable filter options: Ceramic, Poly, Stainless
- Integral with Zone Isolation Sampling Technology (ZIST)
