  1. PP body for spirit transfer pump

    To ensure you're comparing apples to apples: part of the reason the G70 is more expensive is because it uses conductive materials that allow the pump to be fully groundable, thus granting it ATEX certification for safe pump operation in potentially dangerous or explosive atmospheres. Air diaphragm pumps have a lot of rapidly moving parts that can cause static build-up and discharge unless they're grounded, making them potentially unsafe if used around flammable products or vapors. Most air diaphragm pumps are not designed to be fully groundable. The ones that are groundable usually broadcast it pretty loudly by proclaiming ATEX/UL certification, or something like that. Groundable pumps are also usually more expensive than non-groundable pumps, as you've discovered. I'm sure Yamada makes some groundable pumps—they talk about having select ATEX and UL certified pumps here on their website. I'd be surprised if the Yamada you're comparing with the G70 is one of them.
  2. WARNING: Oak Wood Barrel Co.

    I went to the address listed on their website. Here's what I found: There were no businesses here except for Ralph's Courthouse Classic Hot Dogs. Ralph would not sell me a barrel—although I offered him a very good price. He just has hot dogs. I would go back to Ralph for hot dogs, but I would think twice about buying barrels from a company that does business from Courthouse Square in Santa Rosa.
  3. WARNING: Oak Wood Barrel Co.

    The address listed on the dirtcheapbarrels.com website is 570-598 4th St, Santa Rosa, CA 95401. That's our hometown! I'll stop by there tomorrow on my lunch break and let folks know what I find.
  4. passivating stainless

    We use a TIG brush here at TCW for cleaning and passivating TIG welds. Ours is the Capital Weld Cleaner. It works great for us. It's very quick and effective, but unless you're doing a ton of cleaning/passivating it sounds like what Streven proposes would be more simple.
  5. Distillery Pump, FIP vs. AOD

    I would switch it around just a little bit and say that flexible impeller pumps are better equipped to deal with solids. In particular they are better at moving large solids in suspension. Most AODD pumps have a manufacturer's specification outlining exactly how large of a particle they can accept without clogging. The larger the pump, the larger the solids it can accept. Typically, air diaphragm pumps are capable of passing solids in suspension no larger than 1/8 the size of the opening. So, if it's a 1" opening, the largest particle it can take is 1/8". A 2" opening may be able to pass solids up to .25", etc. Flexible impeller pumps can usually pass solids in suspension about 1/3 the size of the inlet, so quite a bit larger. They are, however, subject to the limitations that Tom mentioned, i.e. no high heat above 180 °F and no dry-running. Bear in mind that the 34 CFM requirement is only if you want to run the pump full-out at 43 GPM. You can run it at a slower speed and use less CFM. The math gets trickier, though, and you need to refer the pump curve. For example, you can run the SimpleSpirits 43 with 20 CFM @ 30 psi and still get about 27 GPM. You can run it with 10 CFM @ 30 psi and get about 17 GPM. Generally speaking, the larger the pump, the more efficiently it will use whatever air it has available. In terms of simplicity the Jabsco wins hands down. The head can be rebuilt in less than 10 minutes including a coffee break and there are only four parts: the impeller, the o-rings, the stationary seal and the mechanical seal. The impeller is the only one you'll likely need to touch in the first five years. With TLC and a spare impeller on the shelf they'll last you decades. We've seen it! AODD pumps are not simple. They usually take a few hours to rebuild the wet and dry sides and are more sensitive to over or under-torquing. but they are the best value if you're moving high proof. The pulsations can be an issue, but we've found that adding a pulse smoother tames pulsations significantly.
  6. Proofing barrel and bottle filling

    We sell a lot of fillers to distilleries, so my experience comes from aggregate information. Others on here can (and I hope will) share their own individual experiences. Most commercial semi-automatic fillers are fed in one of two ways: By gravity as you describe, where the final product is in a tank that is above the level of the filler's reservoir. By a pump turned on and off by a level control. The Mori Filler we sell can be fed either way. I would say about 80% of the Mori Fillers we sell are built with a level control/pump. The remaining are fed by gravity. Usually people opt for the gravity version for one reason and one reason only: cost. Unless you designed your facility to use gravity to your advantage, it is much more convenient to leave your tank on the ground. The other benefit to using a pump to feed the filler is that you can run a final filter pass in-line just prior to bottling. You can't do that with gravity. As far as the safety issues you ask about, most of the Mori Fillers we sell to distilleries use a completely air-driven level control and pump system that does not require electricity.
  7. Triclamp accesories

    This is good advice. I've seen a lot of people get tripped up by referring to tri clamp sizes incorrectly (e.g. referring to the size of the ferrule as the tri clamp size – calling a 2" tri clamp fitting 2.5") Attached is a good reference. It's a printable sheet that (as long as your paper/printer are set up correctly) prints true-to-size, so you can hold up a tri clamp fitting to get the size you need to order. Just put a big "X" over the 1" Maxi. They're not commonly used in stainless steel, as the sheet indicates. gvc_doc_00004(1).pdf
  8. Pumps for High Proof Alcohol

    Rust, eh? What kind of pump was it? What material was it made from? We sell a line of groundable AODD pumps specifically for distilleries: SimpleSpirits Pumps. These are air diaphragm pumps, so they require the use of an air compressor to function. The very rough rule of thumb with air diaphragm pumps is that you want your compressor to be capable of generating your desired flow rate in GPM x .75. So, if you want to pump 50 GPM, you need an air compressor capable of generating about 38 CFM at your desired PSI. Alternatively you can get electric pumps with XP-rated components like this, but these get pricey very quickly.
  9. FIP Pumps

    We've sold Jabsco FIPs since the 70s. They're workhorses, and reliable as hell. I love seeing a 30 year old pump come in that just needs a new impeller and o-rings to work good as new. Closest to the one you're looking for is our SQN 50, though it's 5 HP as opposed to 3 HP. We've sold a few Jabscos with XP-rated motors and drives. The XP components get pricey fast, though, and can add a 2-3x factor to the price depending on how many "trimmings" you need. This one had a continuously purged cast iron drive enclosure. I think it was for High West Distillery.
  10. Bottling Equipment

    Someone recently described it as looking like the filler Darth Vader would use. Not sure if that's a downside?
  11. Plate and Frame Filter Sizing

    Well… we do sell cartridge housings and the filters. From pretty basic/cheap housings where you can set them up in series, to cart-mounted 2x30" housings that can filter in series or parallel, to a full 2 x 30" system with integrated air diaphragm pump, like the one pictured right. I don't know much about the Shelco housings you link to. I do know that the style they sell isn't as popular in the beverage industry. It looks like the kind where the filter seal is dependent on how tightly you close the housing. That's pretty common for cheaper filtration setups, but in the beverage industry housings that have twist and lock bases are more common, as they tend to be more reliable. That said, we do sell the same style as the ones you link to for the cost-conscious. It's the polypropylene housing Silk City Distillers references above, also known as an Ametek housing As far as filters, we sell Graver filters. Ther cartridge filters are great – priced well and made in the USA. As I said, we sell a lot of them to distilleries. The number of filters you use and their micron rating depends on what you're trying to remove – large particles (floaties), sub-optical particles (haze), invisible particles (yeast, spoilage bacteria), or some combination of all of the above. Give us a call if you want to talk it over: 707-963-9681
  12. Plate and Frame Filter Sizing

    Not to respond to a thread hijack, but yes they will. Without seeing the housing I can't say that with 100% certainty, but AM is a pretty common end cap configuration with plastic housings like you find in water filters, etc.
  13. Plate and Frame Filter Sizing

    Are you looking at a 40 x 40, a 20 x 20, or…? Also, SCD is right. A lot of product gets left behind in sheet filters. Depending on how much you're processing at a time, you might consider cartridge filters. We sell a lot of these to distillers, who like them because relatively little product gets left behind, and you can even blow the remainder through with inert gas to get every last drop, if you want.
  14. Mori filler with wide mouth bottles (mason jars)

    Wow, interesting! Those are some beefy washers as well. I definitely won't tell people that the Mori Filler is for mason jars, but it looks like it can be done, albeit not perfectly. My hat's off to you. That is some fine MacGyvering.
  15. Polyethylene hose

    A few ways to find out if a hose has plasticizers in it: Talk to the hose manufacturer, or read their spec sheet, if available. Talk to the company distributing the hose. So, in this case head down to the Home Depot and ask one of the orange aprons. Have it analyzed by a laboratory. Not a way to test for plasticizers, but for other adverse effects: soak it for a week or two in vodka. We don't sell a PE hose for distillery use. Regular old PE will likely stiffen and craze after prolonged exposure to Ethanol.
