Product Description

The Wangen Type KL-RQ Pump

The Wangen Type KL-RQ Pump can address your needs for loading the separators in the rigorous operation of your biogas plant.


Loading the Separators

WANGEN pumps perform special tasks in biogas plants such as loading the separators for separating solid and liquid phases.

Conveying the substrates with their mostly high dry substance contents (DS) requires sophisticated pump technology. Optimum pumping results are guaranteed by the flow-optimized suction housing and a constant joint diameter which prevents the plaiting of long fibers.
