It is possible to use the same pump for sampling in several boreholes if the risk of cross-contamination can
be eliminated.
The MP 1/Redi-Flo2 pump is not designed for the pumping of concentrated oils, chemicals or explosive
liquids.
When pumping liquids with a density or kinematic viscosity higher than that of water, a motor input power
higher than the rated power is required. The maximum performance must therefore be reduced by changing
the frequency.
When the MP 1/Redi-Flo2 pump is used, the regulations covering the handling of hazardous material
and possible local regulations must be observed.
The MP 1/Redi-Flo2 pump is not designed for continuous operation like for instance remedial pumping.
Continuous operation may reduce the life of the pump.
Marking: The MP 1/Redi-Flo2 sampling pump system is CE-marked.
