Sorry,cant help you with your question,but heres my set up that I use to clean my breeders,about the same gph you have and it is self priming.http://forum.simplydiscus.com/showth...ump&highlight=
Has anyone successfully connected a vacuum hose to a magdrive 3? Below is a link to the unit from kensfish.

It would not self prime. Called the mfg and they said it would not pump water 30'. Ken said it would not work in line.
The head is only about 4' and the distance is about 30'.
If the pump is on the floor and primed with a 6-8' siphon hose that is about 4' above the floor, and the outlet is a 1" id hose running 30' with about a 2.5 ' rise to the bathtub, will it pump from the tank to the tub? Very frustrating to buy all kinds of adapters to make a project work and it doesn't work.

sometimes if it's not really tight, it won't prime. not sure what you're trying to do but if you just want to drain from 1 tank, why don't you put the pump inside the tank?
Tony, I'm trying to attach my vacuum hose to the pump and send it about 30' to the bathtub. When I tried it early this morning I expected it to be self priming. When it didn't work I called the mfg and they said it wouldn't push water 30'. I boxed it up to return and returned all the adapters to Lowes before I realized I could try priming it first- Fill the siphon hose down to the pump before turning the pump on. It seems like it should work. I hate to ship it back if it would actually work.
if you do it for only 1 tank, i suggest put the pump inside the tank. if you do multiple tanks, i'll suggest return it and get inline pump like Bill because if you break the siphon between tanks, you have to prime it again and make sure no water left insde the 30' hose.
Thank you Tony. I already had a submersible pump, but I wanted one to vacuum. Does the hose have to be full on both ends to hold a siphon? If the pump is sitting 4' below the water line and primed through the inlet and the outlet loops back up a couple of feet will it hold a siphon? Or is there too much air from the outlet to hold it
That is the idea, both ends must be full in order to work properly. I got frustrated and waste so much time when it fails.
Also,the simer is noisy,like using a hair dryer,quiter when water is in it.

This is a little noisy but it pumps like crazy. You fill it to start (a cup) & it's good till you finish. Drains 80% 125g in about 8/10 min.
