Head 17M BLDC Water Pump For Sprinkler System Automatic Irrigation
and Vehicles.
Bextreme Shell OWP-BL43-426T SERIES brushless DC water pump Widely used in hybrid bus, hybrid passenger car, electric vehicles,
trains, ships and other heating and cooling circulation system.
Boosting/circulation/Variable-frequency/Low-noise/centrifugal pump
PWM control/Fault diagnosis
This electronic water pump with compact structure,small size,easy
installation and high efficiency, is single-stage centrifugal water
pumps.The body of the water pump is constructed of high quality
die-cast aluminium alloy.BLDC motor inside allows our pumps operate
continuously without maintenance and is trusted by our customers
for its nice quality long service life and low maintenance cost.

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