GLOBE impellers are made of elastomer compounds, developed for optimum performance and self lubricating for run-dry protection. Additionally, GLOBE impellers have greater resistance to sand and dirt abrasion. All GLOBE impellers are made from elastomers giving them the combined characteristics and multiple properties of rubber, nitrile, viton and neoprene. Description The only impeller in the world guaranteed to run dry for 15 minutes. Globe/barco impellers are made of elastomer compounds, developed for optimum performance and self lubricating for run dry protection. These compounds (niprene) allow these impellers to pump diesel, fuel, engine oil and gasoline without swelling. Also, these impellers have greater resistance to sand and dirt abrasion. DIMENSIONS: 1.5625"OD, .75" WIDTH, .3125" TYPE, 6 BLADES, DRIVE TYPE: SGL FLAT
