What size Bulkhead for Iwaki 100Rlt?

[SteveMarin]

I am going to be asking Melev to make a sump for me, and I would like to know what type of Bulkhead I would need to run my Iwaki 100Rlt externally.

Thanks,
Steve

Minimum ... equal to the size of the pumps intake. Larger is better and especially better if it will be a long run, or you will have valves, 90's, unions, etc.

There is a head loss calc. on the site that also will show you the flow rate increases when using larger piping than what the pump is equipped for. You can always reduce down. You cant effectively increase diameter of physically smaller pipe, obviously.

Well, I do not know the size of the pump's intake, which is why I was asking, so does anyone know where I could find that out? I will be needing 2 of these Pumps on my system, and would really appreciate the help.

Thanks,
Steve
