|Global Water's groundwater purging pumps provide an easy-to-use, high-quality, economical solution for purging, and groundwater testing to a depth of 60ft (18m). The submersible groundwater testing purging pump's 1 5/8” (40mm) diameter minimizes well hang ups and is ideal for use in 2” or larger monitoring wells. Each purging pump is self priming when fully submersed and can be connected directly to a DC power source to begin pumping. All groundwater testing pumps are tough and powerful with plastic construction and a stainless steel impeller. The groundwater purging pumps can pump up to 3 US gallons (11.4 ltrs) per minute. These groundwater testing purging pumps have been used and trusted within the groundwater industry for more than 15 years and are recommended by drillers, hydrologists and field technicians around the world.
The Submersible Groundwater Purging Pumps have an inlet strainer and any sand, rocks or debris that pass through the groundwater testing purging pump’s inlet strainer will pass through the purging pump without clogging it. The ground water purging pumps can be run continuously for 48 hours even in dry conditions without motor damage. The groundwater testing purging pump’s life expectancy is approximately 400 hours, lab tests have shown that the groundwater purging pumps can last up to 750 hours. The submersible ground water testing pumps can achieve low flow sampling by restricting the outlet flow from the end of the sampling tube with a valve (or even by clamping the hose). Restricting the submersible groundwater testing pump’s outlet flow will increase the effective head the groundwater purging pump has to deliver thus reducing output flow. Being a centrifugal ground water testing pump this action will also reduce the current thus making the ground water testing pump use less energy increasing battery life.
