The submersible wastewater pumps of the APNO series are used where the highest demands are placed on a pump. The toughest requirements in combination with long service lives: these are the challenges that the pumps of the APNO series have to meet in any continuous industrial operation. These extremely reliable dewatering pumps impress with highly wear-resistant impellers, heavy-duty PUR cables and a back-to-back mechanical seal made of silicon carbide. Heads up to 90m and flow rates up to 350m³/h can be achieved with this series. The double jacket cooling for conveying in snore mode, as well as the motor protection and food-safe lubricants are just as self-evident as a waterproof cable entry.
