The HS series comprises tough single-phase submersible pumps that are ideal for handling slurries, residues, and other liquids containing solids. The solid cast aluminum body and urethane vortex impeller also offer excellent wear resistance in site applications where the water contains sand and silt in suspension, thus maintaining performance and reliability. The HSZ pumps are automatic models using single float switch. The HS-HSZ pumps can start operation with only 5 mm of water level. Along with the side discharge, spiral design, these pumps come with an agitator to ensure smoother suction of settled particles.
