If PWM Speed Control *is* Used

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 15-90% duty cycle will be delivered.

+12V PWM controlled,

Recommended PWM frequency: 50Hz to 200Hz (nominal = 100Hz)

Recommended PWM Duty range: 15 - 90%

The water pump operates at its minimum speed when the PWM duty cycle is 15%, and it reaches its maximum speed when the PWM duty cycle is greater than 90%.

Please Note:

*The water pump is driven by a brushless DC motor. Ensure that the positive and negative poles are not reversed, and the operating voltage range is DC8.5V to 16V.

*The maximum power of the water pump is 60 watts. Use a power supply with a capacity greater than 60W; otherwise, the pump may not function properly.

*The water pump needs to have water for testing; otherwise, it will detect the lack of water and stop working. Testing the water pump without water will cause it to start and stop multiple times, eventually leading to a protective shutdown.

*The water pump is not self-priming, so the water inlet should be below the water level, or the entire pump can be submerged in water (the pump is waterproof and can be used as a submersible pump).

DC12V 85W Brushless Water Pump

This is a new automotive electronic cooling water pump, driven by a brushless DC motor with an integrated driving circuit, which ensures high-quality performance. Originally designed for automotive applications, the water pump utilizes LIN communication for speed control, and currently, the pump operates at full speed when the green signal line is connected to the negative terminal after powering it up.

The water pump operates within a voltage range of DC 9.5V to 16V, with an approximate power of 85 watts. It features low noise levels and a high flow rate, with a tested flow rate of 45L/Min under no load conditions. The pump is designed to work in environments ranging from -40°C to 120°C.

Specifications:

Brand: BLDCC

Power: 85W

Rated Voltage: DC 12V

Operating Voltage: DC 9.5V-16V

Rated Current: 7.5A

Max pump lift: 9M

Max Flow: 45L/Min

Noise: ≤50dB

Net Weight: 590g

Packaging Weight: 700g

Note: Each water pump comes with a waterproof plug. The orange wire is for positive power connection, the black wire is for negative power connection, and the green wire is for the signal.

Attention:

1. The water pump is driven by a brushless DC motor. Ensure that the positive and negative poles are not reversed, and the operating voltage range is DC 9.5V to 16V.

2. The maximum power of the water pump is 90 watts. Use a power supply with a capacity greater than 90W; otherwise, the pump may not function properly.

3. The pump is equipped with a water shortage protection feature. It will stop working if no water is detected after starting.

4. The water pump is not self-priming, so the water inlet should be below the water level, or the entire pump can be submerged in water (the pump is waterproof and can be used as a submersible pump).

5. The green signal line must be connected to the negative terminal after the power supply is turned on to make the pump work. If the green signal line is connected to the negative terminal before powering it up, the pump will not work. (Users can add a delay-on circuit to the signal line and negative terminal to facilitate use)."

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
