TDH of Vertical Turbine pumps 1

[impeller1]

Folks,

Another question here. I am a young Engineer and I'd like to know how you would go about determining the TDH of a vertical pump in operation. I'd like to perform a test on a pump to determine how it actually performs with respect to its design pump curve. It won't be 100 % accurate as I don't have the system curve, but i'd still like an idea about what to do. Thank You.

They keep trying to look left through their passengers heads and then go CW on the roundabouts here! I'm for banning RH cars on the continent. At least I have the courtesy to fly, take taxis, the bus or walk in right handed territories.

It is an issue to make a field test for vertical turbine pump.
HI standars will help, but depends of size of pump you have.
A complete vibration test, an internal inspection of bearings and wear ring impeller are also required.
