The StingRay sludge pump is capable of handling heavy grease loading in your parts washer. The pump can pass a 2" diameter solid without jamming or stalling. These pumps are ideally suited for pumping used parts washer solution.  Won’t clog like a centrifugal type pump. Centrifugal pump Impellers have small openings that can clog easily. The diaphragm pump is 2 or 3 times better at suction than a centrifugal pump. Many people hope to find a less expensive option for pumping sludge and waste materials but StingRay has found every other pump to be lacking. StingRay uses flap valve pumps exclusively in our own shop for pumping parts washer wastewater.
