I made a nano brewery a few years ago, about 20 gallon a brew. After years of sodding around with a variety of "beer" pumps and solar pumps that have sub-optimal priming and speed/flow control, I have splashed out on some decent Blichman pumps. I did hang out as I was going to make some monster peristaltic pumps out of some old brake drums but realistically with work, kids, DIY and the queue of other stuff it wasn't going to happen any time soon and a pump dying half way through a brew yesterday was the final straw.
So at great expense, I bought two of these Blichmann riptide pumps. Handles boiling liquids, built in vent and flow control and easy to take apart to clean, a brewers dream I have a collection of "brewing pumps" all crap. I've rigged up all sorts of voltage control for 12v solar pumps, and flow control/vents for mains pumps, all ruin the brewing pleasure with constant air locks, lack of easy cleaning and less than great flow control. Some March pumps are a couple of hundred quid and are still useless, no idea why people buy them. I bought one, tested it and sold it quickly. I have another to sell.
Trouble is, being American, they have male 1/2" NPT threads and my quick release hose fittings are 1/2" BSP female. So they will "fit" but not seal, maybe be with a load of PTFE but not ideal.
So I need four 1/2" NPT female to 1/2" BSP male converters in brass or stainless.
I've found them on-line at 15 quid each in brass, so an extra 60 quid. I don't have time to make any, I have a nice porter to brew the weekend after next and have too many other things to do in between. I'm going to the local hydraulic hose place on Friday to get some hoses for the bobcat, they may have something but I'm guessing it will be mild steel, no good for brewing.
Any ideas? Can I put a tap through the 1/2" BSP to make it NPT? I'm not that keen on modifying the NPT on the pump in case it needs to go back under warranty. I believe the pitch is similar, just the angle, 55 degrees on the BSP and 60 degrees on the NPT.
Cheers
