Submersible cast iron grinder pump


The model DGUII, DGFU cast iron submersible grinder pumps are ideal for use in small-scale pressurized commercial or residential sewage transfer systems requiring low flow and high pressure rates. The heavy-duty high chrome iron grinder system has powerful blades that reduce solid sizes for smooth, non-clogging flow. A reversible grinder ring provides longer service life and less maintenance. The pump is small and light weight affording ease in transport and use in temporary installations. FM explosion proof motors are available.
