Brine suspension
Backfilling of hollow spaces is necessary to secure jeopardized pit hollow spaces in former salt mines. The liquid backfilling material is conveyed through pipelines underground and to the mining caverns. Liquid brine accumulates in small salt ponds during hardening. This brine suspension has to be pumped upwards for further processing. A company which has specialized in backfilling operations uses Börger rotary lobe pumps for this. The very compact pumps are transported underground where they suck in the saturated brine with minerals from a depth of up to 7 m and pump them for further use. Heights of between 60 and 80 m are overcome in the process.
