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.

■ Performance parameter

■ PWM character

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

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

■ Electrical parameter

Connector model and the corresponding electrical properties(as shown below)

■ External dimension

■ 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
