Broad range of uses

Because of the limited free cross-sectional area, the pump is suitable for waste water or liquids with solid and long, fibrous particles, as well as coarse solids such as untreated sewage, primary sludge, return and fermented sludge and waste water. Even for the transportation of gaseous liquids, this series provides trouble-free operation.

Optionally, the DRV can run with automatic level control, or assembled into a complete system including HDPE or concrete pit.
