Speed(flow and head) adjusting: only for three-phase dc pump 

Features : 
1.Long life, small size, high efficiency and low consumption, low noise, strong anti-jamming ability, Stable operation. 
2.Brushless, no Pollution,Electronic controlled 
3.Stator and circuit board completely sealed by epoxy resin, solved the problem of leakage generated by the gap of motor's rotor and stator, It can be submersible installed and completely water proof 
4.Our three-phase brushless dc pump's speed can be adjusted by PWM (40~400hz,), analog signal (0~5V), potentiometer (manually). So the flow rate and head can be changed according to customer's requirements. And also we can customize musical pump for small musical fountain. 
5.Three phase brushless dc pump is soft-start, with no impact, great for solar panel use. The circuit board and pump body completely separated, there is no electronic component in pump body, so the pump can use in hot water.  
6.Three-phase pump have many self-protection functions, such as locked-rotor, reverse connection, over-load and over current protection. 
7.There are many kinds of pump with different inlet and outlet dimension, such as 1/2 inch thread, 1/4 inch thread, 8mm, 10mm, 22mm, 27mm etc. And also the dimension of inlet and outlet can be customized according to customer's requirements.
