The Heidra HS200SG is a versatile, 8" (200mm) hydraulic submersible pump capable of passing large solids up to 3-1/8" (79mm), stringy materials and slurries. A remotely-operated slurry gate allows the pump to act as a mixer, ideal for pumping thick, viscous, solids-laden sludges, such as those found in WWTP digesters, environmental clean-ups and API separators at refineries.
