FOR BOSCH DC 12V High-power Large-flow Circulating Electric Brushless Water Pump
Here For sale is 100% new condition electronic brushless water pump from Germany Brand BOSCH.
This pump is with 12V 90 watt high power, high quality and built-in driver circuit.
The pump maybe used for automotive cooling cycle originally, with high-temperature resistant up to 120 degree.
When testing, the waterflow is very large, the peak working current can reach about 7.5A.
Users must pay attention to the positive and negative polarity when connecting the pump to power, it can work normally with DC 9V-16V in real test.

Quick Start Guide:
• Operate pump only after system has been filled with fluid. Avoid air ingestion and cavitation.
• Maximum system pressure of 250kPa. (not to be confused with pump delta-P)
• Pump can be run without the signal (S) pin connected. This will operate the pump at maximum speed.
• Please note, there is a 2 second startup delay if the pump is to be operated without the signal (S) pin connected.
• Do not drive the +/- terminals with a PWM waveform. If terminal S is not used, the pump is used as an ‘on or off’ device (not dithered).
• Permissible voltage range on the + terminal is 8 to 16V. The performance chart to the right is given at 12V.
• Ambient condition range is -40 to 140°C. Maximum fluid temperature of 85°C.
• If the pump detects that it is being run dry, it will turn itself off, try again, but will quit if unsuccessful >20 times.
• A power reset (+12V key cycle) will allow more re-tries.
• The pump will self-protect itself against over-temperature. First a de-rate to 60% speed will occur and then it will stop if temperature reaches a critical level.
If PWM Speed Control *is* Used:
• Terminal “S” driven with: +12V (nominal) PWM controlled, 9 to 110Hz. (nominal = 100Hz)
• If there is no PWM signal within 2 seconds of power-on, the default mode of full speed operation will be used.
• If there is a valid PWM signal, a speed-proportional response to a commanded 12-93% duty cycle will be delivered
