9. Maintenance and service
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
