An electric water pump performs a very important job in your car. It helps move the coolant from the radiator to all the necessary parts in the powertrain. By utilizing a controller, it can determine how much coolant circulates through the engine at given temperature ranges and maintain a target temperature. The coolant cools down the engine allowing it to run smoothly and live longer. But, If the water pump fails, the engine produces excess heat, which sometimes results in irreparable damage.

An electric water pump uses a motor to send coolant from the cooling system to the engine internals. The system engages once the powertrain starts to overheat. The ECU receives the signal, and it initiates the water pump. On the other hand, conventional pumps, sometimes referred to as mechanical water pumps, use the engine’s torque that drives a belt and pulley system. The harder the engine works, the faster the coolant is pumped. The liquid travels from the radiator to the engine block, then to the cylinder heads, and finally back to its origin.

Main benefits:

• Temperature sensitivity
• Lighter
• Longer lifespan
• No negative impact on horsepower or fuel economy

Working ambient temperature: -40℃ to +120℃ (-40°F to +248°F)

Storage temperature: -40℃ to +70℃ (-40°F to +158°F) (up to 100 ℃, but it will shorten the service life)

■ System pressure

-0.2 to 2.5 bar ( 100℃ (212°F).

The service life is more than 20,000 hours based on the rated voltage and 36℃(86°F) ambient temperature.

■ Voltage range

Rated 24V water pump, workable range 18V - 32V

Although the motor can be used in a wide range of voltage and temperature, excessive or too low voltage and temperature will affect the service life of the motor, and the pump can not be exposed to thermal radiation ambient.

Medium liquid: pure water, liquid mixture (Water with below 60% glycol)

■ Electrical parameter

■ Attentions

1. Working ambient temperature:-40℃--120℃, should try to avoid close to three-element catalytic, gas discharge pipe system, and engine during the installation, and ensure the working environment temperature.

2. The installation position of the water pump should as much as possible close to the low water level, to extend the service life of the pump.

4. Please use the pump far from the dusty environment, the dust is harmful to reduces the service life

5. Pay attention to the purity of the water, avoid to jam and impeller-blocked to reduce the service life of the pump
