Hi, It's an old machine with a water cooling system that I would like to improve (especially to save weight). The current water pump is old and over dimensioned, given the bottlenecks in the tubing. 3 wires, 220v water pump, magnetic, 30W, 1,2A 1600L/h I would like to replace the old system for …

Change a 220v water pump for a 12v

Please supply a block diagram showing all connections, including power, for the old pump system, and the same for the proposed new pump system.
