12v pump for 160F/70C water?

[damienperu]

i'm trying to find such a pump for my LC troopy hot water system without any luck. I need to circulate water between heat exchanger and hot water tank, also from hot water tank to mixer... my trusty shurflo 105-003's are only rated to 100F/43C, but I expect to have up to 160F/70C running on occasions.

thanks, good idea but it seems the intercooler pumps are really high flow for cooling, 8 gpm... I need something 1-2 gpm so the water still heats in the exchange instead of ripping through it

 

[damienperu]

I need it to be self-priming, ideally 1 gpm or thereabouts, auto-off between 35-50psi... all the things most RV pumps have

I looked at shurflo's two other RV pumps and they don't specify the water temperature tolerance on the spec sheet

Intercooler pumps won't work for a shower they are for a closed loop system. I found a shurflo pump which does up to 160 I think. My system operates a around 140 and I haven't had any problems. You also want to us a intenral bypass pump so it doesn't short cycle and you want one with Viton seals and diaphragm. They have several models depending on your required flow. I will see if I can find the paper work for the model I am using and post it for you.

Speed controller for pump.

I use the 8000 for my hot water solar setup at my house. Can't go wrong with

how vital is viton?... I'm looking at the 8000's, and I can't get the pressure, control and GPM combination I need with both viton valves and diaphragms, only in viton and santoprene respectively

being listed as industrial and not RV, do you think there is anything that might suffer from the vibrations in an offroader?

Nope. This pump has rubber mounting feet. So vibrations are nothing. I think this will be a great pump for you. It can pump water up 8 vertical feet, it's self priming and won't burn up if it runs dry. Plus it will withstand the temps you're looking for. I know I have run hotter then 170°F water through mine and it still performs great.
