The Lowara DOMO GRI 11 HF is an automatic submersible grinder pump for raw sewage pumping. The high flow (HF) version has a higher flow rate than the standard model but a lower head pressure output. 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 and can greatly reduce the overall system cost compared with standard solids-handling pumps.
