Application Scenarios

Home water supply, buildings, commercial housing, well water extraction, used in scenarios where water needs to be sucked down and pressurized with tap water. Household pressurization, water tank/well water supply, cold-water circulation, and air-energy circulation

400W:

• For 1–3-floor houses, can simultaneously supply 4–5 water outlets
• For 4–6-floor houses, can simultaneously supply 2–3 water outlets

700W:

• 1–3 floors: 5–6 taps can be used simultaneously
• 4–6 floors: 4–5 taps can be used simultaneously
• 7–9 floors: 3–4 taps can be used simultaneously

900W:

• 1–3 floor houses: can supply 6–7 faucets simultaneously.
• 4–6 floor houses: can supply 5–6 faucets simultaneously.
• 7–9 floor houses: can supply 4–5 faucets simultaneously.
• 10–12 floor houses: can supply 3–4 faucets simultaneously.

Features

• Variable Frequency Energy Saving
  • With a high-speed rotation of 4300 rpm/ 4800rpm/4800rpm, the pump automatically adjusts power output according to water demand, saving about 50% energy compared to traditional booster pumps.
• Constant Pressure & Quiet Operation
  • Using AI algorithms to calculate pipeline pressure, it maintains consistent water output across different locations.
  • The multistage impeller design ensures higher efficiency and significantly quieter operation — even lower noise than a conventional 700 W booster pump.
• Comprehensive Protection
  • Includes:
    • Dry-run protection
    • Water-shortage protection
    • Filter clog protection
    • Overheating protection
    • Anti-freezing protection
    • Anti-cracking protection (automatically restarts when water temperature below 3 °C is detected in standby mode)
• Self-Priming Centrifugal Design
  • Breaks through traditional multistage centrifugal pump limitations that cannot discharge air pockets.
  • This allows high self-priming performance, effectively solving traditional suction pain points.
• Stable and Durable
  • Equipped with NSK high-speed bearings, silicon carbide and graphite mechanical seals, and stainless-steel pressure housing for improved reliability and long service life.

 

Product Attributes

• Liquid between +3°C~50°C.
• The pH value of the medium is between 6.5 and 8.5.
• The volume ratio of solid impurities in water shall not exceed 0.1%, and the particle size shall not exceed 0.2mm.

Precautions

1. Suitable for water temperature below 60 °C.
2. For display models or first-time use, please add water to the inlet before operation.
