Application Scenarios

Home water supply, buildings, commercial housing, well water extraction, suitable for applications requiring water suction and pressurization to match tap water pressure. Home water pressure boosting, water tank/tower water supply, well water supply, cooling water circulation/air energy circulation systems.

• Suitable for 1–3 floors: can simultaneously use 4–5 water taps.
• Suitable for 4–6 floors: can simultaneously use 2–3 water taps.

Key Features

• Variable Frequency Function
  • High-speed 5600-rpm motor automatically adjusts power according to water flow, saving up to half the energy compared with traditional booster pumps.
• Constant Pressure and Silent Operation
  •  AI algorithm monitors pipeline pressure for consistent outlet pressure across all locations; multi-stage impeller structure ensures quiet operation.
• Energy Saving and Environmental Protection
  • The fluid components use polymer materials, resistant to corrosion and rust-free; dual-impeller design increases rated flow while achieving energy savings equivalent to a standard 700W booster pump.
• Comprehensive Protection
  • Water shortage protection (auto start when water resumes).
  • Overheat protection, dry-run protection, anti-frost protection, motor burnout prevention.
  • Anti-freeze cracking protection: in standby, the pump automatically starts when water temperature drops below 3°C.
• Self-Priming Capability
  • Breaks the limitations of multi-stage impeller structures lacking air evacuation ability — enabling high-efficiency water suction while solving self-priming difficulties.
• Modern Aesthetic Design
  • legant exterior suited for contemporary home interiors.
• Convenient After-Sales Feature
  • One-button factory reset
  • Built-in timer
  • Clear runtime display for user reference

Product Attributes

• Liquid between +3°C~70°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. Applicable for water temperatures below 70°C.
2. When used for hot water circulation, ensure installation of a stainless-steel check valve (non-return valve).
3. For display use only — avoid dry running on first operation.
