Tar pits

Tar pit

Highly viscous sludge deposits had to be removed from a tar pit. The problem with the pump systems already in use was the fluctuating viscosity of up to 50,000 mPas due to the temperature and the sometimes very large particles contained in the sludge. Both these factors kept causing the pumps to block.

The solution was the Boerger double-pack consisting of a Multicrusher and a Rotary Lobe Pump. The two units were combined in one frame and both operated using a single hydraulic motor. The entire unit is ATEX compliant and is operated immersed in the pit.
