Global Water's inline water pumps provide an easy-to-use, high-quality, economical solution for purging, ground water testing, and well development to a depth of 60ft (18m) or deeper when stacked in series.  When used with Global Water's submersible groundwater pumps the inline water pumps will allow the testing of wells up to 200' deep.  The inline water pump's 1 5/8” (40mm) diameter is ideal for use in 2” or larger monitoring wells.  Each inline water pump is self priming when fully submersed and can be connected directly to a DC power source to begin pumping.  All Global Water inline water pumps are tough and powerful with plastic construction and a stainless steel impeller.  The inline water pumps can pump up to 3 US gallons (11.4 ltrs) per minute.  These inline water 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 inline water pumps can be run continuously for 48 hours even in dry conditions without motor damage.  The inline water pump’s life expectancy is approximately 400 hours, lab tests have shown that the inline water pumps can last up to 750 hours.  The inline water 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 inline water pump’s outlet flow will increase the effective head the inline water pump has to deliver thus reducing output flow.  Being a centrifugal inline water pump this action will also reduce the current thus making the inline water pumps use less energy increasing battery life.
