... so when i try to open the suction to full flow,(keep in mind i have 20hp of pump pumping into 2 common 40 hp pumps pumping from the same suction piping.) i overamp the 40hp pump motors. ...
If you get a chance to try a science fair project, try closing the discharge valves on the 40hp and open the suctions on the 10hp. If you have the capability to check suction and discharge pressures and flow rates that could be an excellent primer.
