Manufacturers claim that rotary lobe pumps can run dry. I'm sure you can if you have a sealless pump. I wouldn't want to try it with mechanical seals.
A centrifugal won't be likely to be able to handle that lower flow - high head combination. Even if they could, you'd likely be running at...
You also could consider a rotary lobe pump. Like PC pumps, they are also positive displacement. They can run dry (unlike PC pumps), take up a lot less space than a PC pump, and the maintenance is a lot more simple.
Viking and Vogel are two manufacturers that come to mind.
Can an electric generator produce any combination of MVARs and MWs such that the MVA output doesn't exceed the rating?
If I have an generator that has a rated output of 115 MVA (GE 7A6), can I produce any combination of MWs and MVARs to my preference such that the power triangle equals 115 MVA...
I am developing a wastewater treatment plant for an industrial location and it's clarifiers and centrifuges, among other equipment, are being replaced (to increase their capacity).
Does anyone know if there is any industry standard or specification for these types of equipment?
Additionally...
