Thanks for the advice. CAPEX and OPEX has been considered. Regarding this the pump is fine.
More relaxed yes. The figures (NPSHa/r) were alright. Just my feelings weren't. ;)
Outlet nozzle is 6"
The NPSHr given by the vendor is 4,00m
I've considered the vapour pressure of 80°C water. The temperature should be below. However temperature will not exceed that temperature.

I have measured from the top of the pipeline (not the center). So the additional height (~0.1m) should cover the additional pressure loss of that 1m lenght. Was never afraid of the pressure but because of the velocity.
I searched a lot at Google and for inlet velocites I always see...
3 times yes.
It's the normal flow rate of the pump and the 8" was selected/ given by the vendor.
My concern is not the nozzle itself. Inlet nozzles tend to be small. But normally (normally means what I saw in the past) the reducer was just before the pump and the inlet pipeline in front of the...
Hello guys,
I know that there are several topics dealing with the maximum pump inlet velocity but I still don't wether I face a problem or not.
There's a centrifugal pump (~1800rpm) connected to an atmospheric storage tank of hot water. The outlet of the tank is a 20"/DN500 line of approx 12m...
