AC220V Submersible Pump

1. Energy-saving VFD system, drastically lower full-lifecycle running costs

The variable frequency system precisely matches dynamic operating conditions of water features without throttling loss, slashing comprehensive energy consumption by 30%–40%. The efficiency of motors under partial load stays steadily above 85%, complying with international energy efficiency standards.

② Stable water supply for high-power clusters with unattenuated water output across the entire head range. A single pump can drive dozens of nozzle sets, ideal for large municipal water feature projects with ultra-high water jets.

③ Outstanding full-lifecycle cost advantages: upfront investment is reduced by 15%, and the 10-year total cost is merely half that of conventional solutions, with simultaneous reductions in electricity fees, maintenance expenses and downtime losses.

④ Modular and standardized framework. Only parameter debugging is required for later capacity expansion and renovation, greatly cutting renovation costs and construction periods without replacing the entire pump unit and pipeline system.

2. Durable Multi-Protected Pump for All-Weather Outdoor Stability

Adopting a multi-layer protective structure, the unit delivers superior weather resistance and wear resistance. It adapts to complex outdoor working conditions and ensures long-term stable operation with low failure rates.

The whole unit is constructed of thickened SS304 stainless steel. Its flow channel resists corrosion from seawater and reclaimed water, reducing pitting corrosion rate by 80% and delivering a service life of up to 15 years.

② Equipped with Class F high-temperature resistant insulation motors rated for 155°C, paired with food-grade circulating cooling oil for heat dissipation. No risk of leakage or contamination in freshwater landscapes, enabling long-duration continuous high-power operation.

③ Triple hydraulic protection against freezing, cavitation and water hammer. No water draining required at temperatures as low as -20°C. It restrains cavitation damage and buffers pressure surges to prevent rupture of pipelines and pump housings.

④ Independent outdoor intelligent electric control module with automatic power-off protection against water shortage and overload, suitable for round-the-clock operation of all types of open-air municipal water features.

3. All-Round Noise Reduction, No Resident Disturbance

Adopting an all-round three-dimensional noise reduction design, the equipment optimizes operating noise through source noise control, structural vibration isolation and water body noise absorption, effectively avoiding noise disturbance and fully adapting to residential area scenarios.

① Adopting a low-speed pump structure of ≤1450rpm for source noise reduction, it effectively reduces mechanical and cavitation noise, limiting cavitation noise within 60dB(A). Equipped with a submersible water-assisted silencing design to weaken low-frequency penetrating noise, it achieves a 20-30dB noise reduction compared with traditional high-speed pumps and completely eliminates the risk of resident complaints.

② Featuring a multi-layer vibration and sound insulation structure, paired with elastic pipe joints and floating foundations to block solid-borne sound transmission, it controls the pump room boundary noise below 55dB(A). Fully compliant with national residential noise standards, it ensures low-noise and stable operation.

③ Submersible water-assisted silencing weakens low-frequency penetrating noise. It delivers 20–30 dB noise reduction compared with traditional high-speed pumps, eliminating risks of resident complaints.

4. Modular Design Reduces Downtime via Easy Installation & Maintenance

The fully modular unit enables rapid disassembly and assembly, cutting installation time by 50% and drastically shortening overall project construction schedules.

Single-side independent inspection port design allows replacement of impellers and sealing components without shutting down the entire unit; routine maintenance can be completed within 4 hours.

Low maintenance threshold with visual operation manuals provided; regular technicians can conduct upkeep without on-site support from factory professional engineers.

Low equipment wear, with the service cycle of spare parts tripled. The annual availability factor of the fountain exceeds 98%, minimizing sightseeing revenue losses caused by shutdowns.
