Robust submersible fountain pump engineered for decorative and music fountain systems that require frequent starting, fast response and reliable operation. The motor is built from DR470 cold-rolled steel with increased winding turns and heavy-duty diving cable (three-phase, four-wire JHS type). Design enhancements include an anti-loosening impeller, a motor chamber finished with imported anti-rust paint, high-performance bearings and shaft, and improved insulation — together these features give the pump a low moment of inertia and rapid response suitable for synchronized fountain applications.
Key features
