Grindex Senior Sludge Pump


Based on the same basic design as the drainage pumps, the sludge pumps come into action when the liquid gets dirtier than can be handled by the drainage pumps. The design even permits converting between drainage and sludge models allowing you to adapt the pump according to the varying conditions.
