Based on our many years of experience, Proactive Environmental Products offer the best line of pumps for low flow sampling projects.
Achieving a flow rate of less than 1 liter per minute is easier said than done. This is especially true when you’re sampling from greater and greater depths. While there are many pumps that can get you to an ideal flow rate, each has drawbacks that can reduce the quality of your sample because they disturb the well water. Through innovative design of their motors and quality control, Proactive™ has built pumps that will not disturb well water.
Reducing disturbance should be your number one goal during any low flow sampling event. Less well disturbance leads to lower sample turbidity, which in turn reduces the variability in the sampling results. This reduction leads to reduced pumped volumes and drawdown; which of course leads to less time spent at each well.
With the variable speed low flow controller, achieving the ideal flow rate couldn’t be easier. These controllers allow the user to precisely control the water discharge with the turn of a knob.
As you can see from this chart, Proactive’s line of stainless steel pumps are ideal for your low flow sampling event regardless of the depth of your wells.
