Applications
The E-Series Permanent Magnet Variable Frequency Domestic Pump is suitable for:
Household water boosting systems for bathrooms, kitchens, showers, and daily water use.
Villas and multi-floor residences require stable pressure at multiple outlets.
Residential water systems have changing flow demands throughout the day.
Areas requiring reliable operation under different temperature conditions.

Core Features
Energy Saving: Permanent magnet variable frequency technology reduces energy consumption by over 30% compared with traditional asynchronous motors of the same power.
Constant Pressure Control: Intelligent monitoring adjusts pump speed according to water demand, maintaining stable pressure during multi-point water usage.
Low Noise Operation: Noise Level: 25-45 dB, with full-load operation below 45 dB, creating a quieter home environment.
Multiple Protection Functions: Leakage Reminder, Dry Run Protection, High Temperature Protection, and Freeze Protection improve operational safety.
Freeze Protection: Temperature Monitoring: Below 5°C, the pump automatically starts to prevent water freezing damage.
Motor Protection: Protection Grade: IP54; Insulation Class: F, helping ensure reliable performance in residential applications.
Water Compatibility: pH Range: 6.5-8.5, suitable for common domestic water conditions.

Brand Customization: Support logo printing, product labels, manuals, and customized packaging.
Appearance Design: Provide customized housing colors and appearance solutions for different brands.
Electrical Customization: Support different voltage, frequency, and plug standards.
Function Configuration: Customize controller settings and protection functions based on application needs.

Leak reminder 
When the pump is running, if there is an accident and water leakage, a reminder will be issued.

Constant pressure water control 
Keep the water output of each faucet constant, practically check the change of water consumption and transmit signals, and intelligently adjust the operation of the water pump to stabilize the water pressure.

High temperature protection 
When the motor temperature is higher than the safe temperature threshold, it will automati-cally power off and cool down to prevent the water pump from burning.

Antifreeze function 
When the power is on, when the temperature sensor detects that the water temperature in the water pump is lower than 5 °C, the water pump runs automatically to prevent freeze cracking.

Low noise and quiet 
Inlligent control, the runtime is as quiet as a library.

Water shortage protection 
In case of water shortage, the pump will enter the protection state after running for a while.
