Can someone help me with the torque sequence and values for the 1.125" and 0.875" nuts/studs that hold the pump halves together? (We can't seem to locate a detailed maintenance manual) THANKS! Robert

I am new to this group and am sure my problem is very basic. For the purpose of learning, I am trying to duplicate the results of a lumped mass model of a vertical turbine pump (I have a copy of the input command file and have typed it into a file). The column pipes and shaft are modeled...

To carry the analogy a bit further: If the baseball pitcher (pump) can't get the ball out of his glove (suction) with his pitching arm/hand (impeller) smoothly, then he could experience disruption (cavitation) of his normal delivery resulting in a bad pitch (reduced performance,damage,etc.)...

Concerning the conversion of kinetic energy into pressure head, an interesting way to think of a centrifugal pump is as a 'throwing device', not a 'pumping device'. Let me illustrate it this way: Get your basic physics book and look at the formula for a projectile thrown straight up. The...
