DC Water Pump Control


Thread Starter


I need to control the flow rate of the water being pumped by a 12VDC pump (http://www.xylemflowcontrol.com/files/RLF Series (F100-196).pdf). For control I'll be using a Siemens S7 1500 PLC. I will use a 24VDC, 10A Power Supply to power two of these pumps which I need to control separately. I was wondering which method of control would be most efficient to control these pumps, just by changing the input voltage or do I need a driver for these?

Also forgot to mention the control will be done using a PID and I need to control them through their complete operation (OFF to 100%).
