2. General description

The MP 1 submersible pump is specially designed for the purging
Page
and sampling of contaminated groundwater in boreholes with an
4
internal diameter of at least 50 mm.
4
The pump is powered via an adjustable converter in the 25 to
4
400 Hz frequency range. At 400 Hz, the pump provides a flow
5
3
rate of 1 m /h at 74 metres head.
5
5
The pump must always be powered via the

converter. See fig. 1.

2.1 Applications

11
The MP 1 pump is designed for the purging and sampling of
12
contaminated water.
12
The maximum sand content of the water must not exceed
13
3
50 g/m . A larger sand content will reduce the life of the service
14
parts and increase the risk of blocking of the pump.
14
Water temperature: +1 °C to +30 °C.
14
All pump components are made from materials not giving off
14
foreign matter to the pumped liquid. This ensures that the sample
taken is neither influenced nor altered by the pump.
To avoid cleaning the pump and to eliminate the risk of cross-
contamination, permanent installation of the pump is
recommended.
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 pump is not designed for the pumping
Caution 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 pump is used, the regulations
Note covering the handling of hazardous material and
possible local regulations must be observed.
The MP 1 pump is not designed for continuous
operation like for instance remedial pumping.
Caution
Continuous operation may reduce the life of the
pump.
