IET Pump Curves

These Grundfos submersible pumps are made of stainless steel and retrofitted with PTFE to handle the rigors of contaminated groundwater pumping and continuous operation in remediation and solid waste applications. Built to deliver optimum efficiency during periods of high demand, all Grundfos pumps provide low, long-term operating costs and high operating reliability regardless of the application.

Grundfos Enviro retrofitted submersibles meet government guidelines for environmental equipment and have been proven through extensive use in the field.

Typical clean-up operations include water table depression techniques to isolate and remove dissolved contaminants. This pump design has been used extensively in a vast percentage of the Countries Landfills, being used successfully in recovering and pumping Leachate, in side slope, vertical and horizontal applications.
