Product Description
24V High Lift Electric Coolant Pump 6 Bar for DC Fast Charging Gun Cooling
Product Features
The OWP-BL60H is a brushless motor driven electric water pump with PWM signal speed regulation, designed to drive coolant flow in cooling circuits. It operates continuously or intermittently and features self-diagnosis and fault feedback functions.
Scope of Use
- Primarily used in server cooling, fixed base station cooling, and charging terminal cooling
- Compatible with antifreeze (maximum 60% glycol)

Function Description
- Reverse connection protection: Pump won't start with reversed polarity and resumes normal operation when corrected.
- Dry-running protection: Automatically stops when water runs dry and resumes normal operation when water is restored.
- Stall protection: Automatically stops when waterway is blocked and resumes when circulation is restored.
- Over current protection: Reduces speed until stopping when protection current is exceeded.
- Under-voltage/over-voltage protection: Reduces speed until stopping when operating voltage is exceeded.
Note: Mechanical switches should not be used to directly control the motor. Never operate the pump without water.

Recommended Installation Methods
Installation Position:
- Mount on fixed bracket of the device
- Consider vibration and noise requirements in installation location and fastener design
- Avoid water accumulation on or inside the connector
- Secure connector properly to prevent damage from wiring harness vibration
Bracket Requirements:
- Design must consider vibration and noise requirements
- Secure wiring harness to prevent movement relative to pump connector
- No other parts allowed to be fixed on the pump
