What pump can handle backpressure

Justin/TiV · 06/11/2007, 08:46 PM

I saw this in a thread awhile back, but don't remember the pump. I'm needing a feed pump for my calcium reactor that will give me a rock steady drip. My MJ isn't doing the job...

anyone have any suggestions ??

Thanx

Eheim.

Buy a peristaltic.

You'll never get a "steady" drip out of any aquarium pump. Even the nice Eheims.

A decent peristaltic is cheaper than an Eheim, too.

How do people get consistant drip rates then ?? there has to be a pump that can handle the back pressure, or something I can do. I've also heard of teeing off the feed pump so that some of it runs back into the sump.

I need to do something, I'm adjusting it everyday, and I need it to be steady so my params are rock solid

Thanx for the responses so far

do not run an extra pump run a bleed line off your main pump.

THat is, IMO, the worst option. It gives you the least control over flow rate.

I've been using an Iwaki bellows pump for about a year now and it is by far the best method I've tried.

The one I have is adjustable from 1-100ml with no variation whatsoever.

You can find them on eb@y really cheap. .just make sure you get one that is the correct flow rating for your setup and 110v.

anyone else have any ideas on a great pump

As someone mentioned, Iwaki's handle back pressure quite well. As I recall, you do need to make sure you get the model that is designed for back pressure situations.

there's usually more of them for sale

I'd keep an eye out for Gorman Rupp or Iwaki ones.

They are usually listed in either the "other pumps" or the photo processing equipment sections.
