Zoeller Shark Series grinder pumps are designed for grinding the waste into a fine slurry ideal for applications in high-pressure sewage systems, agricultural facilities and water treatment lines. These grinder pumps feature cast iron construction that offers high strength, wear-resistance and vibration damping and a powder-coated epoxy finish for resistance against abrasive fluids. They also come equipped with a hardened stainless-steel cutter with a scissor-action cutting mechanism that eliminates chances of material binding and roping around the cutter edges. Additionally, the oil-filled motor of these pumps is thermally protected along with external cooling fins for uniform heat dissipation rates and protection against overheating conditions. Choose from a wide range of these Zoeller grinder pumps, available in brass, plastic and bronze impeller materials on Raptor Supplies.
