Pump Pre-Filter Ideas??

[BrAin]

Looking for DIY pre-filter ideas for my return pump. The one I hastily made is cutting my flow by at least a third. I've got a 1" threaded suction. My other idea was to take a short piece of larger pvc and drill a thousand holes in it and cover with a filter sock. Lets see what you are running and hear some other ideas.

May I ask why you are trying to put a pre-filter on a return pump?

[troy tucker]

What tipe pump and how is it hooked up to the sump?

[mistahoo]

Instead of drilling holes, you could cut lines. It wouldn't clog as much as the holes. I think that putting any type of prefilter on a return pump would lower flow, would it not?

they key is to allow the most surface area for filtration so you can get the most flow with the least pressure drop. this is why many sumps have the return pump in a partition where the water must first pass through a large filter sponge. for pond use, the whole pump is put into a filter box that has filter batting wrapped around it. i have used this method before in palludariums.

This is what I do for my sump. I guess that sponge block is my "prefilter"? I've got a sack of ceramic rings in there along with airstones and an internal Tetra whisper 10g filter.

Got a Quiet one 6000 that sits in the sump. My filter isnt at the stage I want it to be so I used some poly-fil in one part and pieces get loose every once in a while.

I put a threaded strainer on the intake of my mag5, got the piece @ city pets. You could then slip a sponge over the strainer to act as a prefilter.

any threaded strainer for bulhead fittings would work wouldnt it texsun? the longer the better...

This is what mine looks like. I don't use a sponge. I use blue filter pad at the bulkhead. It stops everything but the water from getting to my pumps. hope this helps.

I went ahead and made another filter sock and drilled some holes in a piece of 1-1/4" pvc that is about 6" long. Slipped the sock over the pvc and used a coupler to connect to a 1-1/4" slip x 1" threaded bushing. Flow is much better than my previous attempt.

Yes, agreed.
