Specification:

DC12V micro brushless impeller centrifugal water pump, it has a fully sealed rubber filling structure and supports PWM signal stepless speed regulation. 

The measured voltage can operate between DC 5V-12V, and it can be used at low voltage with low power and low flow rate. The water pump line is about 35cm.

The internal workmanship of the water pump is good, and the outer shell is made of transparent material. It was originally installed on the water dispenser equipment. 

The measured working current is around 0.25A at voltage of 12V, the power is 3W, the nominal maximum flow rate is 2.4L/min, and the maximum lift is 3 meters.

This impeller pump is not a self priming pump. The impeller must be filled with water before it can run out of water. 

The water pump is strictly prohibited from idling, as idle dry grinding may make strange noises. 

Without water, idle dry grinding can also affect its lifespan.

It is built-in driver brushless water pump, as long as the red wire is connected to the positive pole and the black wire is connected to the negative pole, it can run at high speed. 

It is strictly prohibited to connect the positive and negative poles incorrectly. The blue wire is a PWM signal for speed regulation, and if speed regulation is not required, 

the blue wire will not be connected. PWM speed regulation supports a duty cycle signal of around 10-20KHZ, with a signal voltage of 5V.

The pump weight is 30 grams.

Package Include:

Mini Pump x 1PCS
