Griffin

Griffin nonclog pumps have an impeller capable of handling stringy materials and solids up to 4.5 inches, the company says. A large clean out port allows for removal of debris larger than 4.5 inches without removing suction pipe or hose. Pumps can deliver more than 17,000 gpm at head capacities of 240 feet or more. Pumps come with electric or diesel engines, with internal fuel tanks for 24-hour operation on most models.
