Horizontal chemical centrifugal pumps are made of polymers and feature high performance. They are operated by a direct-drive motor (max. 3000 rpm) for fast liquid transfer and/or drainage with flow rates ranging from 6 to 75m³/hour. Their open impeller allows pumping of even very dirty liquids in continuous flow, with an apparent viscosity of 500 cps (at 20 ° C) and small suspended solids.
