The GY-series is a submersible grinder pump ideal for sewage disposal with small pipe cross-sections, large delivery heads with relatively low delivery rates, pressure drainage systems in topographically difficult areas. GY breaks up solids carried along in fractions of a second, so that plastic pipes with cross-sections from 1½" are already sufficient for the pipelines. In this way, the costs for the use of materials and the laying of sewage systems can be significantly reduced. ATEX available.
