Design
Via a crane mounted in the socket for lifting equipment (3) the submersible motor
pumps (7) are lowered into the collecting tank or removed for maintenance work.
The guide rail arrangement (10) is connected to the flanged bends (14) of the tank
insert (8). It enables the submersible motor pumps to hook onto the flanged bends.
For buried installation the collecting tank is closed with a tank cover (1). Depending
on the variant, the collecting tank cover is designed as a two-piece or single-piece
