BESST’s Panacea Pumps are powered by cycles of pressurized nitrogen gas or air which lifts the sample or purges water to the surface. BESST’s Timer Control Units (TCU) allow for easy control and automation of the discharge and recovery cycles when using BESST Panacea Pumps. The TCU is housed in a sturdy Pelican case for increased portability and field durability, and features an easy to use interface. A dual cycle timer controls the discharge and recovery cycles times, and a pressure gauge provides a read out of the pressure being used. Timer controls are extremely flexible, allowing different times for discharge and recovery. This versatility enables use in a great variety of wells: low or high water volume, fast or slow recovery rates.
