Transfer pump sizing
Transfer pump sizing
(OP)
Hello everybody
In a new piping system here in my school , they make a transfer pump for the generator between a bulk tank and a daily tank , but the problem is that the pump is not pumping , It's pumping only in manual mode using handle ,
I want to check if the pump is sized perfectly for this system , And I don’t really know from where to start
Any example of transfer pump sizing would very helpful

RE: Transfer pump sizing
If so, do you have the right air supply pressure on the PCV to this pump for this head of say 3m

You didn't finish your diagram, e.g. you didn't label the tanks, so we can't tell if the pump is installed backwards. You also didn't show how the handpump is arranged, where the tank vents and drains are located, and you didn't show the stop valves that enable you to service the transfer pump.
See if you can produce or find a more complete diagram, and perhaps provide some illuminative photographs.

Do you understand how the fuel system is _supposed_to_ work?

The outlet of the bulk tank connected to the inlet of the pump , then the outlet of the pump to the inlet of the day tank,
when the pump start , the fuel reach the pump but doesn’t go all the way to the day tank, if the pump is off there a handle to pump manually and it does pump it to the daily tank, there is no filter in both tanks.
I'm not really familiar about how fuel systems works , but since there was no design for this fuel system I think the pump is undersized.
I will get more details and I will draw a more detailed diagram
Thank you so much for your time.
