The Grundfos MP 1 submersible pump is specially designed for purging and sampling of monitoring wells with a diameter of at least 50 millimetres or bigger. This pump is equipped with a re-usable PTFE tube. The high capacity of this pump allows for quick purging of the measuring point. By setting a low pumping capacity the same pump can be used for sampling. The pumped medium comes into contact only with steel and PTFE.

The pump motor is controlled by an adjustable frequency converter. Due to the variable setting of the frequency, the capacity of the pump can be adjusted from 0 to 2 m3/hour. This results in a steady flow of anaerobe water. Built-in safeguards protect the Grundfos MP 1 and the convertor against overload. The actual frequency can be read from a display. The set is delivered fully assembled.
