Recommended Wire size is (Based on 3% voltage drop)

* The length of the wire means the distance from pump to the battery

Temperature parameter

Medium liquid temperature: -40℃ to +85℃ (-40°F to + 185°F)

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 - 32VAlthough the motor can be used in a wide range of voltage and temperature, but excessive or too low voltage and temperature will affect the service life of the motor, the pump can not be exposed to thermal radiation ambient.

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, 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.

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

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