If you didn't buy it from China the company you bought it from did ;)

A few have used these and they prove more than up to the job: http://www.ebay.co.uk/itm/371128026468, you dont need to go mad trying to cool these spindles down, they are quite efficient and shouldn't really get hot.

Simple bypass from output to input - just a tap that can be opened gradually and you can set the pressure exactly as you want it. This was standard practice on the main Grundfos 3 kW pumps that circulated water in my Launderettes when I had them - simple gate valve and in that case a pressure gauge. High enough to fill a washing machine PDQ, but not high enough to bust the flexible hoses !

I would add a 2nd pump to circulate through the spindle then hook the chiller to a thermostat like this
A pond style water pump will work fine I have a box of 20 of them I can send you one for free if you want and will use less electricity than the pump in the chiller.
With a reasonable size res of 20l's the chiller will only need to run a few minutes in an hour and I bet that water pump in the chiller uses quite a bit of juice.Last edited by Desertboy; 04-07-2017 at 08:28 AM.

What size pipe do people use? 6mm OD?
I managed to get a lot more powerful pump, pushes a good amount of water but when I connect up my plumbing, it struggles to flow. I have turned an adaptor to go from 1/2 to 1/4 inch (roughly) but the hole might be too restrictive.
Should I move up to 8mm piping?
Thanks

8mm ordered anyways to check. I'm not sure how free flowing the water should be through the spindle, I went as far as removing the pipes and I get a slow flow, so I dont think its that.
