It is a Ingersol Dresser, Vertical turbine high lift pump used in a water supply plant. It has a 350 hp motor and is rated at 210 L/s. The serial # is 1292-9017/19. I need the curve for an efficiency audit I'm doing on the plant and the manufacture does not seem to be any help. I can calculate the results but need the pump curve for the theoretical.
Not enough information yet.
Serial Number would get you the curve from IR.
Usually the turbine head has a tag on it that states the model, number of stages, and impeller trim. That would get it.
Could you also provide the total differential head (this will also be shown on the nameplate), and the current (and voltage) that the motor is drawing.
Are you aware that Dresser is now part of FLOWSERVE. I would be very surprised if they can not provide this information. As a last resort you could ask for a duplicate replacement pump. Don't feel guilty if you need to use some inventive approach to get them interested.
