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.
