Thread: Fixing leak in Alloy Pump Housing

Another source. Giving 'em a plug because they have a store the wood working show.

ULTRA BOND aluminium repair rods 5PC PACK - Robson's Tool King Store

Way way OT but i wonder could the Durafix type product be used to solder ally to steel? This thread is the first time i have ever heard of such a product. Thinking mag blocks with ally spacers.....

Ew

Bruce,
You could drill and tap, weld or apply one of the above mentioned epoxies. For what it is worth, (Seeing as the pump is still working o.k) i would wait until the end of the fire season, then disassemble the pump for repair also check seals bearings etc while you're at it and decide if it is worth repairing.
There is bound to be more corrosion in the housing, clean with a rotary wire brush and then carry out the repair for the hole, when that is completed use devcon to repair the rest of the volute housing,it is easy to form before it become hard, this way you will regain the efficiency of the pump. I have used devcon for pump housing repairs, it will withstand the pumping pressures and vibration of that pump.I hope your friend does not really need it at any time.
Regards
Ted

Thanks to all, for the various methods of fixing the leak.
The problem was solved by filling the small hole in the pump housing with "J B Weld". This is a 2 part- type epoxy purchased in Castle Hill Sydney at "Jaycar Electronics"
It comes in 2 small tubes.
The pump is now operating perfectly with no leaks, & thanks to all, including overseas Forum members for the valuable input to the question raised back in early February.

Bruce

I must have missed your post originally Bruce, and have just seen the update. I'm glad you have had success with JB Weld, but I would have recommended tigging first, and Devcon second, only because I have used it in the distant past with excellent results. Devcon used to and probably still make plastic steel, aluminium, bronze, wear alloy, (with carborundum grit in epoxy IIRC) and I think plastic cast iron, and although I have not used them all, I have used several variants and all worked well. That is not to take anything from the suggestions from others here, they are possibly more recent additions to the market, and I simply have no experience with them. As Ted C has suggested, it may be worth pulling the unit down when summer is over, and building up any worn or corroded areas, so that the pump remains serviceable for the longer term. Any of the recommended epoxies could well do a great job, but I have only used Devcon materials, and once repaired a cement mixer bowl with some stuff called Cerraguard IIRC, but I have not used it, (the mixer), since, so can't say how good it has been. Regards,
Rob.
