Quick guide from the manual
The 18W Micro Solenoid Pump is designed for water pumping applications. It requires a 230V/50Hz power supply and must be installed in a dry environment. The pump must not be immersed in water and is not suitable for swimming pools, marine environments, or corrosive media. Ensure the water tank system is isolated from electromagnetic vibration.
Product Overview
This is a micro solenoid pump intended for water pumping. It operates on a continuous duty cycle.
- Rated Voltage: AC 230V
- Rated Frequency: 50Hz
- Maximum Power: ≤18W
- Operating Mode: Continuous duty
Operating Conditions
- Ambient Temperature: 0 °C to 60 °C
- Fluid Temperature: ≤35 °C (recommended: clean water at 20 °C)
- Storage Temperature: -10 °C to 70 °C
- Insulation Class: Class H
Performance Parameters
- Flow Rate (0.7Bar back pressure): 27–36 cc/min
- Maximum Pressure: 2.0–4.0 Bar
- Vacuum: ≤-0.25 Bar
- Coil Temperature Rise (ambient 25°C): ≤140 K
- Service Life (continuous operation): ≥500 hours
- Noise (at 20 cm distance): ≤58 dBA
Electrical Safety Specifications
- Hi-pot Test: Withstands AC 2500V, 5 mA for 2 seconds between terminals and metal housing in cold state.
- Insulation Resistance: ≥100 MΩ under DC 500V in cold state.
- Power Consumption: Steady-state power ≤18W at rated voltage.
- Temperature Rise Test: Coil temperature rise shall not exceed 140 K (ambient 25°C).
Operation & Testing Guidelines
Flow Test: Under 0.7 Bar back pressure, supply AC230V/50Hz and measure the water output during the first minute.
Pressure Test: Close the outlet valve with no air in the system; the pressure gauge should read 2.0–4.0 Bar.
Temperature Rise Monitoring: After continuous operation for 1 hour, the coil temperature rise must not exceed 140 K (ambient 25°C).
Warnings & Limitations
- For water pumping only; do not use with other liquids or corrosive media.
- Do not immerse in water; ensure electrical parts are kept dry and isolated during installation.
- Not intended for swimming pools, boats, or other damp/special environments.
- The accompanying water tank should be designed with anti-vibration measures to avoid safety risks from electromagnetic vibration.
Maintenance & Service Life
Under standard operating conditions, the pump can operate continuously for over 500 hours. Periodically check insulation integrity and connection status to ensure safe operation.
Practical help
Common problems
Pump overheating or failing
Check if ambient temperature is within 0-60°C and fluid temperature is ≤35°C. Ensure continuous operation does not exceed coil temperature rise limits.
Excessive vibration or noise
Ensure the water tank system is equipped with anti-vibration measures and isolated from sources of electromagnetic vibration.
Before use
- Verify power supply is AC 230V/50Hz.
- Ensure the pump is not immersed in water.
- Check that the fluid is clean water at 20°C.
- Confirm the installation environment is not damp or corrosive.
- Ensure the water tank system has anti-vibration measures.
