GrAK-500/20 slurry pump

The GrAK-500/20 slurry pump is a horizontal centrifugal single-stage cantilever pump with a closed-type impeller. It is designed to pump gravel, sand-gravel, slag, ash-and-slag and other abrasive and highly abrasive slurries with a pH of 6 to 8, a density of up to 1300 kg/m³ and a temperature of up to 70 °C, with a volumetric solids concentration of up to 30%, a solids microhardness of up to 9000 MPa and a particle size of up to 6 mm. The GrAK-500/20 pump has a single-casing design with a casing lined with organic-bonded corundum, and is connected to the motor via a flexible coupling or a V-belt drive. Wetted parts material: cast iron. Shaft seal: gland packing with flushing water supply. Gland flushing water consumption: 3.5 m³/h. Applications of the GrAK-500/20 pump: mining and processing plants and mining and metallurgical enterprises, thermal power plants, cement plants, diamond and gold mining enterprises, crushing and mineral processing lines, and other industrial sectors.
