Applications :
– This model can be used for all kinds of water using of household,water circulation, tap water pressurization, garden irrigation,vegetable greenhouse water supply, etc.

Key Features :

1. Dry Run Protection: Automatically triggers protection to prevent mechanical damage and overheating when the system runs without liquid, extending equipment service life.
2. Overload & Overheating Motor Control: Real-time load and temperature monitoring limits power output or triggers emergency shutdown to protect the motor from burnout.
3. Integrated Frequency Converter: All-in-one design reduces installation space, eliminates signal interference, and enables precise, stable motor speed control.
4. High Efficiency Permanent Magnet Driven Motor: Delivers 10-30% higher energy efficiency than traditional motors, with low noise, low vibration, and reliable performance under variable loads.
5. Stop Delay Function: Allows delayed shutdown to complete pressure relief and pipeline emptying, avoiding system impact damage and ensuring smooth operation.
6. Small Leakage Detection: Accurately identifies micro-leaks via pressure/flow monitoring, issues early warnings to prevent waste, corrosion, and safety hazards.
7. Programmable Menu: Enables custom configuration of operating parameters (speed, pressure, logic) for flexible adaptation to diverse process scenarios.
8. Pressure & Current Monitoring: Real-time tracking of core operating data supports predictive maintenance and ensures long-term stable system operation.
