Maximize the volume of each pump stroke! When used in conjunction with BESST’s Panacea Pumps, BESST’s Volume Boosters enable sampling and purging from wells with water columns as small as 4 feet, and can be used at depths up to 2,000 feet below ground surface. The greater pump stroke volumes created by the Volume Booster means that the same Panacea Pump can be used in both the purging and sampling processes, dramatically reducing time spent in pump deployment and retrieval.
