Can you use these filter systems to filter a batch before bottling. My bottles always have sediment and yeast at the bottom and are not very pleasing to the eye.

I wouldn't. You'll oxidize your beer.So, my fermenters won't take pressure- anybody know if you can filter pushing with a pump?

How so? If the filter pack is purged of oxygen with either water, sanitizer, or CO2, and then you push beer into it, where is the oxidation happening?
The pump is pushing beer out using air. I don't see how it's possible to purge the pump of oxygen...it's an open system. Would that be enough O2 to oxidize the beer? I'm not sure. But I would guess this is a reason people use a siphon and not a pump to push/pull beer out of a fermentor and into a bottling bucket or keg.
The pump doesn't use air, it's the rotary motion of the magnetically driven impeller. All moving parts are totally submerged in beer with no oxygen contact there. The only oxygen contact would be in through the top of the fermenter, where there's little or no motion going on, like in a bottling bucket.
Because the filter housings have purge valves your able to get basically all the beer out expect a small amount that stays in the filters. I would say the loss is maybe worst case 6 oz.

why not just use 2 kegs? i dont have any fermentors that hold pressure. just rack into one keg then push the beer with co2 through the filter...
Ah- because this is a special case. I'm kegging 3bbl of beer, more or less, and having to do it 15g at a time would be a little tedious. Still, it's definitely an option.
I'm brushing the dust off this thread to ask a question:
I just tried to filter a cider during transfer from primary to keg. I sanitized the whole shebang, put all the backsweetening in the keg, and started the transfer, with a 1 micron filter in the housing. I used Notty for the ferment, and (as always) it flocc'd like a champ: the cider was pretty much "newspaper clear" so I felt ok going straight to the 1 micron. Using CO2 to push from primary seemed to go ok, but I had a bit of trouble with the filter. The cider went in with no problem, but at the "out" flange I had TONS of gas along with the cider heading to the keg.
I made sure all the connections in the filter itself were tight, and tightened the HE*L out of the hose clamp holding the tubing onto the "out" flange. At the outset there WAS a small cider leak at the "in" flange but a twist on that particular hose clamp solved that. But as far as the gas chugging from the "out" flange: nothing seemed to help. I'm afraid I was aspirating air into the system somehow, but couldn't figure out where it was coming from.
One thing I noticed: TONS of carbonation coming out of solution in the filter housing. SO, safe to assume that what I was seeing is just the CO2 being agitated out of solution as the cider moved through the filter?
Thanks!

It usually takes me more like 30 to 40 min per 5 gallons. 5 to 10 sounds too fast.
