Do you have a pic?Just remembered ive got a beer cooler pump that's been getting in the way. Is there anything usefull in that
Do you have a pic?
Some can be used but most are just circulating pumps and do not produce enough pressure to flow around constricted torch waterways.
Yep I use the rectus fittings on my water cooler.the alternative as mentioned by hotrodder earlier in this thread are rectus 21 quick release fittings which are readily available in a range of sizes, and are suitable for air and water.
I ended up cutting out a steel plate and tack welded 3 brackets onto it, 2 to hold the fan/radiator and one to fasten the return coolant tube to.

and how it looks assembled, nothing too complicated here.

the copper tubes are made from 3/16" car brake pipe with unions soft soldered onto the ends. the pipe at the back is the pick up pipe from the tank below it.

the inlet and outlet of the pump are for 10mm hose, so I ended up running a die down them and threading them 1/8" bsp. I also did the same for the radiator too, although they are readily available with 1/4" bsp bushes on them. the feet of the pump motor were also threded M6 as they are already drilled 5mm. I fitted the fan behind the radiator so that it blows air over the pump too. after 15 minutes running like this the motor was only 5C above ambient temperature.
and the hose connections using the 1/8" bsp quick release connections for airbrushes.

and the lid shown from below

the long tube is the pickup and has a filter on the end, and the short tube is the coolant return, which goes just below the surface of the coolant to reduce the amount of air in the coolant, which the pump doesn't like as it drastically reduces the flow and pressure. the motor is bolted to the lid by stainless screw with O rings under the washers to seal the holes.

and running with the bench power supply Im using.
it seems to be working well so far, apart from the quick release couplings as they leak badly if you put any sidways movement on hoses, so I've got a couple spare lpg quick release fittings that will be modified to fit. I'm doing this as I already have them and will probably be unused for the next 20 years otherwise.

At least use deionised water with it.I'm using old style monoethylene glycol at about 25%, hopefully it should never get cold enough to cause me issues. I'm using a Unipart antifreeze, but I guess this one would do as an alternative.
