QSP Submersible fountain pump

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

• Motor housing: DR470 cold-rolled steel with anti-rust coating
• Electrical: three-phase, 50 Hz, rated 380 V (operating range 342–420 V)
• Cable: three-phase four-wire JHS special diving cable
• Impeller: anti-loosening device to prevent detachment during operation
• Mechanical: high-performance bearings and special shaft for frequent starts
• Insulation and protection improved for reliable performance in fountain systems
• Available in a stainless-steel variant (QSPF) for corrosive or marine environments

Primary applications

• Musical and decorative fountains
• Urban and landscape waterscapes
• Aquaculture and pond circulation
• Low-lift irrigation, sprinkler systems and farmland water supply
• Industrial and civil supply & drainage systems
• Water diversion in hilly terrain and drainage of low-lying areas
• Use in chemical plants, salt farms, seawater discharge and certain mining environments (select stainless variant where corrosion resistance is required)

Operating conditions & recommendations

• Submersion depth: 0.5 m to 5 m
• Maximum water temperature: 40 °C
• Allowed medium: non-corrosive water with sand content < 0.1%
• pH range: 6.5 to 8.5
• Recommended to operate near rated head for best performance
• Electrical supply: three-phase, 50 Hz, rated 380 V (acceptable 342–420 V)
• Installation: provide appropriate start protection (starter/protector) and reliable grounding

Typical specification reference (confirm exact configuration before ordering)
