Non-Clog pumps from Griffin can pump more than 17,000 gallons per minute, and they can pass a solid measure just over 4 inches. A side clean-out port allows the simple removal of large debris in the water without separating the pump from the suction pipe. The Non-Clog pumps develop discharge heads of 240 feet or more. The pumps are available in vacuum-assist, diaphragm prime or compressor prime, and they can be powered by electric or diesel.
