Gravel pump impeller basic part number is 137, the function of gravel pump impeller is to impart and direct the centrifugal force to the sand gravel slurries. Compared to slurry pump impeller, gravel pump impeller has larger internal profile that allows bigger particles for handling the most difficult higher abrasive slurries. And Impeller expulsion vanes reduce gland pressure and intrusion of high concentrations of solids in the gland area. Efficiency is maintained by minimising suction side recirculation.
Sand Gravel Pumps and Spares are used for handling of the most difficult higher abrasive slurries, containing solids too large to be pumped by a standard slury pump. It is suitable for delivering slurries in Mining, explosive sludge in metal melting, dredging in Dredger and course of rivers and other fields.
