IM vertical half-submersible chemical pumps, made of polymer, are characterized as high-performance pumps for fixed installations with pump immersed directly into the tank and operated by a direct-drive electric motor (max 3000 rpm) for fast fluid drainage with flow rates ranging from 6 to 75 m³/hour and head up to 38 m.

The special design and no internal mechanical seals (subject to heavy wear) ensure no accidental spillages to be collected in the tank. The open impeller allows continuous pumping of even very dirty liquids having apparent viscosity up to 500 cps (at 20°C) and small solid particles.
