Return pump question

[dfm34]

I am setting up a 75 gal corner overflow with a 30 long sump. My drain line is 1.25 and my return is .75. I was looking to use either a mag 9.5 or eheim 1262 as a pump (900 GPH)My return line will be PVC with 4' vertical, 3' horizontal, 2 90's, 1 ball valve, 1 union and 1 45 degree. This gives me 620 GPH after head loss. My question is is the enough or do I need a larger return pump?

Thanks.

Thanks I just realized my drain is 1" the 1.25 reduces down should not make a difference right?
