RS156
Product Features
This pump features a permanent magnet variable frequency motor with intelligent chip drive control, delivering exceptional energy efficiency. It reduces power consumption by 40%-70% compared to traditional pumps while maintaining high performance.
The pump features a shielded motor design to prevent internal leakage, with select models utilizing encapsulated construction to eliminate condensation-related motor failure from ambient temperature fluctuations. High-strength ceramic shafts and bearings combined with internal circulation design ensure extended service life and reduced operational noise. With a wide voltage range of 160-260V, the pump maintains consistent performance across varying power conditions. The system offers both multi-mode and single-mode operation control, featuring:
• Modes: Constant power | Constant voltage | Energy-saving | Adaptive | Night
• Protections: Dry-run | Locked-rotor | Voltage anomaly | Overload
