The Lowara DOMO GRI 11 HF SG is a single phase submersible grinder pump. It has the same power output as the popular Lowara DOMO GRI 11 (SG) but has a different impeller design meaning it delivers higher flow, but lower pressure. The Lowara DOMO GRI are a range of grinder pumps, capable of cutting through solids so that they can pass through the pump and discharge pipework easily. These pumps are designed to be incredibly efficient and reliable, with a very low risk of impeller clogging.
