  1. Yep, they're $5.50. Are you sure you want 1/2" barb? You mentioned threaded in your original post, so that'd be the 1/2" NPT adapters rather than 1/2" barb. These are not yet on our website, but you can give us a call at 707-963-9681 to order.
  2. Hey @HedgeBird All the air and liquid ports on the G70 are replaceable and swappable. If you look at the ports you'll see little pull tabs that hold them in place. Flojet makes tons of different connection styles. They come to us with 3/4" barb fittings in/out, but we also stock 1/2" barb, 1/2" NPT threads, and 3/8" tube push-connect (aka John Guest). The air inlet it is less flexible. I've only seen 1/4" barb fittings for that port. As Tom notes, the short length of hose to whatever-fitting-you-want is the best option. It may seem like a stupid design, but Flojet's typical end user is OEMs who are going to install it into some other kind of assembly, like a beverage dispensing machine. When we first introduced the G70 into distilleries I think it took Flojet by surprise a little that they had a "hit" on their hands with the little guy, as they were marketing it towards more chemical applications.
  3. We sell Ferrinox labelers with a square bottle upgrade. It's basically a tray with a pneumatic cylinder that pushes the square bottle through at a controlled rate to apply the label evenly. You can use the same labeler to do rounds or squares by just removing the pneumatic tray. https://store.tcwequipment.com/products/eko-10-labeler
  4. Still available in Santa Rosa, CA.
  5. In general, viscous products do best with high vacuum and high pressure. Flexible impeller pumps are a good middle-of-the-road solution with some caveats. They're not perfect, but hard to beat for the price. Viscous products are kryptonite for centrifugal pumps, so they're right out. As Jedd notes, Air diaphragm pumps work well as long as you can size them properly. Viscous products pump best with higher pressures, and consequently higher airflow, which means a big, noisy, expensive compressor. They're a great solution as long as you already have an air compressor on-site. Once you're buying an air compressor for the sole purpose of powering your pump, they're not such a slam dunk. I have a local customer that pumps syrups, sauces, and other honey-like substances. He bought a Ragazzini peristaltic pump about fifteen years ago and swears by it. They pull nearly perfect vacuum and can deliver over 15 bar of pressure. They're used to pump concrete and rock slurries, so molasses is easy. The only downside is the price, as they start around $10k.
  6. 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.
  7. 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.
  8. 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.
  9. The brass one will definitely not work.
  10. 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.
  11. 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.
  12. 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.
  13. 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).
  14. 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.

  15. 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)
