How about more info?Be specific with the system info.What kind of presses?Doing what?What is the expected operational pressure?What do you mean they quit working?Read wrong?

Ok, I have taken this system over from a competitor so I don't know how many feet are in the water loop. There are apparently no drawings of the system from the previous tenant as well. I have spoken

We have seen similar vibration problems with pumps of this type. The resolution of the most recent problem required the addition of pulsation dampers to both the suction and discharge sides of the pu

I am sizing a relief device for a situation in which a centrifugal pump could overpressure a vessel. Generally speaking, I have seen cent. pump curves that denote the y-axis as Total Developed Head (T

Just finished looking for some Goulds pump data, the 3196 being discussed in another thread.Went to the Goulds website and was told to download some pump selection active x program. OK.Had to registe

Just a crazy old Structural that likes to break things - and fix them.If we believe all the oil advertising and engine mfgs, they say the worst engine wear happens during the first few seconds of star

It would end up using more power than using pumps with a more suitable curve, but could you use a recirculation loop to allow the pump to move more water and slide down the curve to a point where you

Sorry, but I think you have not understood how NPSHa is calculated. NPSHa = p-Z+V+fWhere p is the absolute pressure head in the tank feeding the pump. This is 33 ft for a tank open to atmosphereZ is
