  • output of water pumps.....

    For a 5 gallon dye bath which would be better......80gph or 250gph?

    Im half afraid the 80gph wont cause much movement, but am afraid the 250gph will be way too much. Any advice from the guys that already use such pumps? Thanks!

    The dye won't require nearly as much agitation as the anodizing tank. The water pump will also have to be able to handle the dye temperature. Since there is no corrosive mist, aeration (air bubbles) might be easier.

      im half tempted to get one and submerge it to see if it holds up in teh hot dye.

      I dont think aeration would be a great idea, I cant have any "surface activity" as far as bubbles causing any mist on the surface.

      think the 250gph is going to cause a very heavy agitation in the small 5 gallon containers?

        It depends... If there is a single output, it will be rather violent especially if the output is pointed up or if the amount of solution is only 1-2 gallons. If you connect a piece of plastic tubing to the output, with 10-15 1/16" holes in it, it spreads the force out. I use a 287 gph pump in my electrolyte (3.5-4 gallons of solution) using the plastic tube method and it provides great aggitation with a slight 'rolling' of the surface of the electrolyte. You could also point the single output along the side of the bucket, where it will create a swirling of the solution.

        Just fill a bucket with tap water and try it. If its too violent, attach a small piece of tubing to the output and put a clamp on it. (Don't clamp the input to the pump. It may damage it.). As long as you only use it in the dye tank, you can probably get by with just about any type of clamp, but if it is used in the electrolyte, use a plastic or aluminum clamp.
