Connection: connect the black wire to ground lead and yellow wire to the signal of your system. Hang the red wire in the air.
Three-phase DC pump controller (only S & A series): All electronic components are put inside of the control box, and separated from pump body, so pump body can bear higher hot water (100℃ max)
How to choose pumps:
1. Confirm your operating voltage, current, head, flow, and the size of inlet & outlet. In general, there is no flow when the head achieve the maximum head marked by factory. So if you require the pump is able to meet a certain height and also meet a certain flow, you should choose a higher maximum head than you need. Please consult us or refer to the performance curves.
2. Confirm the shape requirements, such as the type of interface, the direction of inlet & outlet, etc.
3. Confirm the working environment, such as the temperature, the medium, etc.
4. Confirm the functional requirements, such as the time control, the flow control, the speed control, etc.
5. Please feel free to contact us if you have any questions need our help during choose the pump.
