2.1 Applications
The Grundfos MP 1/Redi-Flo2 pump is designed for the purging and sampling of contaminated water. The
maximum sand content of the water must not exceed 50 g/m3. A larger sand content will reduce the life of the
service parts and increase the risk of blocking of the pump. Water temperature: +1 °C to +30 °C.
All pump components are made from materials not giving off foreign matter to the pumped liquid except
PFOS/PFOA. If you are going to sample for these parameters, please ask your distributor how to act. For other
contaminantsthesampletakenisnotinuenced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.
TheMP1/Redi-Flo2pumpisnotdesignedforthepumpingofconcentratedoils,chemicalsorexplosive
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.

4. Transportation and storage
4.1 Delivery
4.1.1 MP 1/Redi-Flo2 pump
After production, the pump has been ultrasonically cleaned and packed into a polyethylene bag. This means
that the pump has not been in contact with dirt or detergents after cleaning and it is untouched by persons.
4.1.2 Converter
The converter should not be exposed to unnecessary shocks and should be handled like sensitive
electronic equipment.

6
4.2 Storage
The pumping system should be stored in a clean and dry area.
4.2.1 MP 1/Redi-Flo2 pump
Storage temperature: –20 °C to +50 °C.
If the pump hasto be storedafter use, it mustbe cleaned thoroughly before storing. See section 9.Maintenance
and service.
4.2.2 Converter
The converter should be stored in a clean and dry area. Storage temperature: –10 °C to 45 °C.

The pump can be installed either horizontally or vertically. The pump
dischargeportshouldneverfallbelowthehorizontalplane.Seeg.2.
During operation, the pump must always be completely submerged in
the liquid.
The pump performance is controlled by changing the frequency. The
installation of a valve in the discharge pipe is unnecessary and with
regard to the water sample directly inappropriate.
If a valve has been installed anyway, make sure that the pump is only
operated against a closed valve for a very short period.
Otherwise the heat generated will cause the pump to stop.
If a non-return valve is installed in the discharge pipe, it must be
installed at least 0.5 metres above the pump. This is necessary
to ensure that the air in the pump is compressed so much that the pump contains water when it is being
submerged.

During operation, the pump and motor must be completely submerged to
ensure the necessary lubrication of the shaft seal and cooling of the motor.
If the pump pumps more water that the borehole can yield, there is a risk that the water level falls below the
level of the pump inlet and that air is therefore sucked into the pump.

Before they leave the factory, Eijkelkamp Soil & Water has programmed the converters for use with the MP
1 (converter art . no. 122746) and for use with the Redi-Flo2 (converter art. no. 122747) pump. The rest of the
functions are blocked by a password and can only be changed by Eijkelkamp.
That is why only 3 buttons are used to operate the MP 1/Redi-Flo2 pump.
Switch 1: to start the convertor, after connecting it to the power supply (switch turns hard).
Switch 2: to set the direction of rotation to Forward (FWD) (Function REW is disabled by Eijkelkamp, because
this will damage the pump).
Switch 3: to set the speed from 0 to 400 Hz.

9.1 Maintenance
If the pump is used alternately in several boreholes, it must be
decontaminated before every sampling event or before possible storing.
Clean the pump, cable, straining wire, etc. on the outside. Then dismantle
the pump. Thoroughly clean the pump components before reassembling
the pump. See section 10. Dismantling and assembly.
As the demineralised water (approx. 25 ml) in the motor may have been
wholly or partly replaced by the contaminated water, it is necessary to
rellthemotorwithdemineralisedwater.Seesection5.4Checkingof
liquid in motor.
Forthereplacementofwearpartsincludingimpellers,seeg.10,aservice
kit (art. no.: 12274301) is available. The kit includes two complete pump
stages. Replace the wear parts including impellers as shown in section
10. Dismantling and assembly.
In addition, a service kit (product number 12274311) is available. This kit
includes wear parts for two pumps, i.e. 4 washers, pos. 285, and 4 seals,
pos.207.Seeg.10.
The rinsing water from the decontamination and the motor liquid
must be collected and disposed of in accordance with local regulations
9.2 Service
The MP 1/Redi-Flo2 pump is specially designed for the purging and sampling of contaminated and/or toxic
groundwater. As a precaution, Eijkelkamp Soil & Water cannot undertake to service the pump.
