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