JUNQI JP100-24V Brushless DC Motor Pump, PWM Control 24V 100W Fuel Cell Circulating Cooling Electric Water Pump

Main Features:

1. Constant power: The water pump power is basically constant when the supply voltage dc9v-16v changes;

2. Overtemperature protection: When the environment temperature over 100 ℃ (limit temperature), the pump start self protection function, in order to guarantee the life of the pump, it is recommended the installation in the low temperature or air flow better location).

3. Over-voltage protection: The pump enters DC28V voltage for 1min, the internal circuit of the pump is not damaged;

4. Blocking rotation protection: When there is entry of foreign material in the pipeline, causing the water pump to plug and rotate, the pump current suddenly increases, the water pump stops rotating (the water pump motor stops working after 20 restarts, if the water pump stops working, the water pump stops working), the water pump stops working, and the water pump stops to restart the water pump and restart the pump to resume normal operation;

5. Dry running protection: In the case of no circulating medium, the water pump will operate for 20 seconds or less after full startup.

6. Reverse connection protection: The water pump is connected to the DC28V voltage, the polarity of the power supply is reversed, maintained for 1min, and the internal circuit of the water pump is not damaged;

7. PWM speed regulation function

8 and fault output high level function

9. Soft start

♣Basic information

♣ Mounting instruction:

♣ Temperature parameter

Medium liquid temperature: -40℃ to +120℃ (-40°F to + 248°F)

Working ambient temperature: -40℃ to +100℃ (-40°F to +212°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.

♣ Connector model and Pins

♣ 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. In order to reduce water resistance, should as much as possible to reduce the number elbow in piping in the installation, ensure no any elbow within 20 cm from the pump.

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

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