The Davey DT22K sits in the middle-upper tier of Davey’s K-Series cutter pumps, engineered for demanding wastewater duties where conventional open-impeller sump pumps risk blockage. Built around a single-channel centrifugal hydraulic with a cutting leading edge, the DT22K slices fibrous matter such as rags and wipes before discharge, helping to keep both the pump and downstream pipework clear. This design choice reduces unplanned stoppages and maintenance costs in real-world sewage and trade-waste environments.
