Any one familiar with this pump?Iwaki Magnetic PumpMD-15R-NL39A buddy just gave me one, I wish to use it in my 2319 factory...

Specs look good..5.0 GpM11.1 Head1/2" fittingsDoes it have a Poly head?

[Buzz Buzzard]

Some form of plastic I think it was rated to 80'c

Thats around 176'F, correct? I bet its Poly. Usually there is a safety factor built into that too. Id say your pump will work just fine as long as you are not moving boiling water/wort. Id go for it if it was me.

I use an Iwaki for the 2319 and love it. I actually think it is that same pump. I talked to them about the temperature of the head and was told that it would be fine but because it was designed for reefs they never needed to test it at a higher temperature. I have used mine for 2+ years and many batches and have had no issues. I used this pump to replace a March pump and it is head and shoulders better IMO. I recently added an auto-vent that makes priming supper easy even though this pump seems to prime extremely easy.

He has many of them if any one would like to own one.

How much?

How much?

I second that, a back up is always nice.

PM me info on cost, etc. I'm looking to rebuild my rig and will need a second pump.

GRFPP= glass reinforced polypropylene. Good to 180 dF. Good to move strike & sparge water.

I will get a number from him and post a pic or two somewhere.PM me if you are interested.Sorry about posting such things here in this forum.It was not my intention.My plans for it are for my new fermentation chamber the plan is to use a chest freezer to power it.The goal is to put a radiator of some sort in both the freezer and my chamber with this pumpmoving coolant through the loop.I think for my purposes it is way too nice a pump for this.

Agreed. I'd get a cheap submersible pump for your application.

I bought a pump and met Buzz Buzzard. Thanks Buzz! I think this will work nicely.Cheers,Rich

I was worried about using this for transfering hot wort from the boil kettle so I looked up some properties on matweb. Looks like the soft point for GFRPP (I checked about 40 different versions) is around 235-280 deg F, so I think its probably safe for transferring hot wort after its boiled. I wouldn't want any super heated vapor going through it though.Cheers,Rich

Seagis?

[SchwanzBrewer]

Seagis?

seagis gets super heated vapor going through him due to the combinations of eating nuclear wings and the friction from glacies dipping sausage in the spicy hole.

[Buzz Buzzard]

Cool I am glad you are happy with the pump.I am sorry I have been slow getting the details together for the other requests for them out there. I will endeavor to get a pic up of them. $80 each + actual shipping costs for those who want in.

The glass reinforced polypropylene is fine for boiling wort in the capacity that we use it, short duration, low system pressure. If you are running a pressurized system and pumping 210F fluid 24/7 it would die pretty quickly. For a homebrewer, it will do anything we would ask it to for years on end. Like drez said, manufacturers build a lot of safety factor into equipment ratings because they need to take into consideration the customers who are going to push the equipment to the limits. We don't even come close to pushing these mag drive pumps to their limit.

Only thing I worry about is polymers leaching into my beer because of degradation due to high temps. For $80 I can kill it without being hurt too much though. That's why I checked the material pages for the soft point, that is where it starts(ed) to break down, but it is well above boiling in all cases.Cheers,Rich

Softening point and solubility are two different things. Polymers aren't going to leach into beer.
