|Rotapump Model 100
Rotapump is a surface-mounted pump developed to quickly and easily pump 2-inch monitoring wells where the water level is as deep as 200 feet. This wellhead pump is easily transported, set up, and operated using a portable drill or electric motor powered by a car battery. Because the pump uses a dedicated pumping tube stored in each well, decontamination of equipment between wells is eliminated. The pump is self-priming from any depth and can pump sediment laden water with no difficulty.
The pumping rate can be precisely controlled at a constant rate from 1/4 gpm up to 6 gpm or more. Sediment-free low-flow purging and sampling are easily done by placing the pumping tube inside a stilling tube.
