I. Core Technical Architecture
Permanent Magnet Synchronous Motor Technology
Rotor system constructed using permanent magnet materials; energy efficiency meets the IE5 ultra-high efficiency standard.
Offers over 30% energy savings compared to traditional asynchronous motors and increases torque density by approximately 50%.
Features a fully sealed, waterproof design with Class H (180°C) insulation.
Intelligent Variable-Frequency Control System
Built-in 32-bit ARM processor supporting stepless speed regulation (0–100 Hz).
Equipped with a pressure sensor for real-time monitoring of pipeline network pressure; accuracy reaches ±0.1 bar.
Supports both constant-pressure and variable-pressure operating modes to meet diverse application requirements.
II. Professional Performance Characteristics
High Efficiency and Energy Saving
Peak efficiency reaches 82%, offering 40% energy savings compared to standard booster pumps.
Maintains over 75% efficiency across the wide high-efficiency frequency range (30–80 Hz).
Standby power consumption <2W; features intelligent sleep/wake functions.
Reliable Operation
Head range: 15–60 meters; flow rate range: 1–8 m³/h.
Operating pressure range: 0.2–1.0 MPa; maximum pressure limit: 1.6 MPa.
Utilizes a dual-sealing structure (mechanical seal + oil seal) for a service life exceeding 10,000 hours.
III. Intelligent Control Functions
