    Pump type for transferring pure ethanol

    A centrifugal pump head on its own is unlikely to be the cause of any potential hazards. It's the motor turning the pump head you should be concerned about. Some motors can spark, which can ignite flammable vapors. You'll want to make sure the pump's motor is rated for use in areas where potentially flammable vapors may be present, either through normal use or in the case of equipment failure. Air diaphragm pumps—though they pose much less of a sparking risk—are not necessarily intrinsically safe. Both laminar flow and the reciprocating action in the pump both have the potential to build up static electricity during normal use. As a result, many air diaphragm pumps are available in ATEX, UL, etc. versions that are fully groundable, so that any static electricity that does build up can be dissipated to ground.

    Small pump for bottle washing station

    Depends. We use the quad on the electric Minimax. For our Rinser/Sparger, however, most facilities rinse with their house water that's been filtered/treated, and flows under its own pressure. No pump needed, so we just build a timing circuit.

    Small pump for bottle washing station

    Interesting idea. You wouldn't need to plumb off the gas exhaust. It might actually make things more difficult. Just run a 'Y' from your gas line. One end goes to the G70 and the other end goes to the second nozzle—or more appropriately, a second regulator so that you're not delivering the same psi to the pump that you are to the bottles for sparging. The G70 will take about 30 psi and the sparging nozzle will work with less than 10. I don't know how you'd get it to work from the exhaust port, because the G70 will only exhaust when the pump is running. Would be very cool if you could find a way to make it work. Anyway, they don't use a whole lot of compressed air. Some facilities run the little Flojets off of inert gas exclusively. Exactly. Sounds like you're referring to Flojet's Quad pumps. Anyone thinking about using these pumps should note that Flojet warns against their use with products that have a flash point below 100 °F.

    The brass one will definitely not work.

    The Flojet G70—like all air diaphragm pumps—can be deadheaded (run against closed discharge outlet) and will stop running automatically when the outlet closes. So you'd need to figure out a way to jury-rig it so that the discharge closes when the bottle is removed. Or you could manually close a valve.

    Barrel Warning

    From the article: Ha! These guys have been at it for a few "Christmas seasons" at least. Glad to see they're finally getting some heat from authorities, but will probably turn up like a bad penny using a new domain and too-good-to-be-true prices.

    To filter or not to filter...

    Typically the health hazards of DE are related to its loose powder form. If inhaled it is a known lung irritant, like fiberglass. The OSHA consequences are why filtering with DE powder has been almost entirely eliminated in the beverage industry, and replaced with plate & frame or lenticular filtration. 40 x 40 sheets and lenticular modules often contain DE or Perlite mixed with a binding agent like cellulose, so you're no longer dealing with a loose powder. The DE is contained in the media, so you don't have the same risks for lung irritation or concerns about proper disposal. Anyway, in spite of the concerns, diatomaceous earth on its own is not asbestos. It's still widely used as a natural flea powder. Some people even take it as a dietary supplement, though it sounds pretty dubious. The linked article is about people that work in DE mines, particularly those that worked before 1950.

    Screw top types and bottles

    Yes, special equipment is needed to install roll-on pilfer proof (ROPP) caps like the ones you're describing. You need a capping head that is sized and adjusted to match your bottle, cap, and cap liner material. The head is installed in a capping machine capable of applying the proper pressure and rotation to form the threads and seal the cap. It's surprisingly complex to get right and easy to get wrong, resulting in caps that don't seal properly. There is, in fact, a whole 200+ page book written on the finer points of properly closing a bottle with a screw cap. We sell a capper, but the manufacturer requires bottle and cap samples to test and adjust the machine prior to shipping. This is to avoid issues with improper sealing. Most reputable manufacturers will require the same. There are only a couple of companies that manufacture the closing heads. The engineering requirements are quite complex. I'd avoid ROPP caps if you're only planning for a small project and stick to t-top corks. Much simpler, unless you're planning on moving all of your production over to ROPP (which is a nice way to go).

    Pair of Large Tanks

    We have two large tanks for a nice price. These tanks were brought in for a customer whose operations had to downsize while the tanks were still on the water from Europe. We're trying to help him out by spreading the word on these tanks, but he (our customer) will be the ultimate seller, so any offers would have to go through him. I'm attaching tank specs. They don't photograph very well because they are lying on their side. These will likely have to be transported by flatbed, though they could be loaded into a 40-foot container. In short, transportation will likely be fairly pricey, so a West Coast buyer will have a price advantage. 120 HL (3,170 Gallons) Closed Top, Conical Bottom Tank * Diameter: 2100 mm * Body height 3500 mm * Leg height 330 mm * AISI 304 BA Stainless Steel construction * Adjustable leg levelers * Top manway, diameter 400 mm * 3" TC port * Support for ladder * Lower manway door * Connection for sample tap NPT 1/2" * Conical bottom * Bottom drain connection TC 3" * Partial drain connection 3" TC Original Price: $14,995 145 HL (3,830) Gallons, Closed Top, Flat Bottom Tank * Tank diameter 2300 mm * Body height 4500 mm * Legs height 330 mm * Adjustable leg levelers * Sloped bottom 5% * AISI 304 BA Stainless Steel Construction * Rectangular bottom manway 530 x 420 mm * Bottom 3" TC Connection * Support for ladder * Circular top manway Original Price: $14,295 Customer is pretty keen to sell, so I'm sure reasonable offers will be considered, and we can put any interested parties in touch.

    Distillery Hoses

    Brewline has a chlorobutyl liner. Generally we recommend chlorobutyl for up to about 50% ABV, after which UPE (like on GlideTech Distillery) exhibits superior resistance over the long term. The other thing our customers like about Glidetech Distillery relative to Continental hoses is the "channels". Continental's hoses are flat are flat on the exterior, which lets liquids pool and gather on the ground if the hose is blocking the flow to your drain. Glidetech has ridges so liquids can flow past to your drain. And, of course, the smooth exterior cover that makes it easy to drag (hence the "glide" in GlideTech)

    Mori filler mod for infinite adjustability

    Dang. That is really clever and very cleanly done. I was going crazy trying to think of a rack and pinion setup or something, but I really like this. I'm going to see if we can get something going in production once our busy season settles down.

    Bottling line help

    Sorry if I derailed the thread, David, or intimated that any issues are the result of user error. Not my intention. Since we have Mori Fillers working well in hundreds of distilleries I was keen to hone in on why exactly it wasn't working for you. I've yet to find an issue that couldn't be root-caused and corrected. Still, it sounds like you're past that point and I totally understand. If you choose to sell your Mori Filler to another distillery I'd be glad to help you sweeten the pot for the next owner by providing a set of nozzle seals and o-rings free of charge to the new owner. Just have them reach out to me.

    Bottling line help

    Hey David, Sorry you're having trouble with the fill levels. The fact that you mention you're also having fill level issues with the Enolmatic leads me to wonder if there may be something else going on. Perhaps with the glass? The Mori Filler—like all level fillers—operates on pretty basic principles, and fill level issues can usually be corrected once the source of the issue is found. To get accurate fill levels you need to have a tight seal against the mouth of the bottle. Overfills are caused because the seal is not adequate, and it can usually be corrected by lowering the nozzle cone, and thus increasing the tension against the mouth of the bottle. Underfills are usually the result of a blockage in the nozzle that's not letting air vent out. It can be corrected by disassembling and inspecting the nozzle to clear out blockages. Give me a call if you'd like to troubleshoot. I think I may have talked to you or your wife last year briefly.

    Distillery Hoses

    High end compared to garden hose. Low end compared to your still. But about average compared to industrial hose in general. Industrial hose is not cheap, but you get what you pay for. GlideTech Distillery is tough as hell, reinforced with SS helices, does not impart odor/flavor, and is built to conform to a variety of sanitation and safety-related specs. If you can find cheaper hose that ticks all the same boxes—particularly as it relates to the unique challenges posed by safely transferring distilled spirits—let me know. I'll carry it. Industrial hose isn't sexy and you can't feature it in your tours like you can your still, so I understand why people just starting to outfit their distillery are surprised that something as "simple" as hose isn't $1/foot. But at the end of the day it's the only thing separating your product from the floor.

    Pump safety

    Depends on the version. There are three: The Gravity-Fed version doesn't use a pump. The Electric version uses the Flojet Quad pump. The Pneumatic version uses the G70. You can see the breakdown here.
