Thanks for your thoughts. I'm somewhat relieved because of them. It's a 2.5"dia. propeller-driven flow meter that uses tiny rare earth magnets placed at 180 degrees, N and S poles, to make a near sine wave signal against a coil with a soft iron core. Your basic "magnetic...

Thanks for your good response. I suppose it's a slight semantic question as to the meaning of "suck." When a baby "sucks" (from his/her mother), he/she lowers the pressure inside the mouth using tongue and mouth muscles, and by your corrective reasoning, atmospheric pressure forces...
Thanks, Scipio, for your careful reply. Something is still unclear to me however, not really knowing the NPSHR and lacking the training to use the concept effectively. With a centrifugal pump, is it necessary to "suck" from ABOVE the water level, ie., to have some sort of resistance that way...
I have a 1.5 Hp centrifugal pump and I want to use it to move water through a tank to create a piece of test equipment for a flow-meter design. My question is, "Am I wrong to position the entire pump BELOW the tank?" In other words the suction port would take water downwards from one point in...
