AMT Self-Priming Cast Iron Centrifugal pumps are designed for a broad range of high capacity applications, including dewatering, liquid transfer, circulation, drainage and irrigation. Dual volute design reduces radial load on motor. The centerline discharge feature is specifically designed to prevent vapor binding and makes for convenient piping connections. Pumps are designed to handle liquids with solids content or dissolved solids and debris. All models are fitted with self-cleaning, semi-open stainless steel impeller, which can handle 1/2" diameter semi- solids. Built-in check valves for fast priming are standard on all units. Fill and drain plugs for easy installation and servicing.
