Recessed Impeller Option
Hydromatic pumps are available with recessed impellers which are virtually impossible to clog and they perform up to shut-off head without damage.

Recessed impeller pumps are ideal for a broad range of sewage and special waste handling situations including high head and low flows and where large solids are present. The recessed impeller creates a liquid vortex in the volute which directs all spherical solids, slurry, sludge, grit, stringy or fibrous material through the pump without clogging. The pumps are virtually impossible to clog.
