Snyder Industries 15 Gallon Heavy Duty Black Open Top Cone Bottom Mixing Tank

Hand work over an open rim

Buy this one for the duty, which is work done by hand into the top of the vessel. Fifteen gallons is a mixing quantity rather than a storage quantity: a concentrate diluted for the day, a sample batch, a dip or rinse bath, a make-up station beside a dosing pump. An open top is what you choose when a bag has to be emptied in, a paddle has to go round, a probe has to go down or somebody has to see the surface of the batch while they work it. Every one of those is slower and more awkward through a lid, and on a vessel this small a lid costs more access than it buys protection. The number that decides it is the rim height. At 28 inches the top edge sits at about waist height on an adult standing on the floor, which means a jug, a hose, a scoop or a hand goes in over the edge with no step and no reaching up, and the operator can look straight down at what they are doing. That is the whole ergonomic case for the shape. What you accept in exchange is that the vessel contains liquid and nothing else: dust, rain, insects, tools and whatever the ceiling above it drops all go in freely, so an open tank belongs indoors or under cover, and something goes over the top between shifts. Vapour and odour also leave the vessel straight into the room, which makes the ventilation around it part of the installation rather than an accessory on the tank. Under the vessel is the other half of the design, because a cone has no flat floor and this sheet publishes no stand, no leg, no frame and no cradle. That support is a separate item settled before the tank is ordered, and nothing here invents a height, a load or a material for it; the cone bottom tank stand compatibility matrix is where the question gets answered across makers. Whatever holds it also fixes the clearance under the cone, which decides whether a pail or a pump suction fits beneath it. Check the volume against the batch you actually make in the tank sizing calculator before you commit to the shape, and take the freeboard from the tank sizing guide: on an open vessel the freeboard matters more, not less, because there is no lid to catch what a hose or a paddle throws up.

Two fifteens and a seventeen: reading the small end

The middle row is the one worth stopping on, because it holds the same 15 gallons on the same 17 inch circle and is a different vessel in every other respect. The sheet names SII-1520000N45 a cone bottom tank with sump, lists it at 36 inches tall against this tank's 28, and gives its empty weight as 51 pounds against 9. That is eight inches more height and a large step in listed weight for an identical volume, and the sheet explains none of it, so we print the figures and offer no theory. What a buyer can act on is the description the maker gives: one of these is an open top mixing vessel and the other is listed with a sump, and those are two different ways of getting the last of a batch out. The third row goes the other way. 1850000N51 holds two more gallons at 17, on a wider 19 inch circle only 24 inches tall, at the same 9 pounds as this tank. Four inches lower at the rim and two inches wider across is a real difference on hand-work duty: lower is easier to reach into and wider is easier to get a paddle around, but a wider, shorter cone holds a shallower column, which is the opposite of what helps a batch drain. Pick by how the work is done. If somebody is standing over it with both hands, rim height wins. If the point is that the vessel empties itself cleanly between products, the taller column wins. If both matter, buy the one whose rim your people can work at and put the effort into the support underneath.

Still deciding between these? Freight to your ZIP often settles it; the wider tanks ship differently. Or call 866-418-1777 and we will walk the table with you.

An open rim, a cover field, no outlet published

• Where the batch leaves: the outlet field reads 1 Manway / Lid and no bulkhead, valve, thread or size is published anywhere on this sheet. So no fitting is claimed here. Tell us how the batch is meant to come out and we will confirm what this part number carries before it ships rather than print something the maker does not list.
• Drawing off in practice: on an open vessel of this size the usual arrangement is a suction line over the rim to a small pump, or a hand pour into a jug. Carry the line on its own bracket, not on the rim, and keep the foot clear of the bottom of the cone so the last of the batch is not the first thing it lifts.
• The open top itself: the defining feature, and there is nothing here to seal, nothing to vent and no headspace pressure to manage. The sheet's manway field reads 17" Manway Cover, the same number as the listed diameter, and that field is printed as given and claimed as nothing. If you need a cover or a splash lid, ask and we will confirm what is available against this part number.
• Breathing: an open vessel sits at atmosphere, so no vacuum builds while it is drawn down and no pressure builds while it is filled. That removes one failure mode and creates another, because whatever evaporates goes into the room around it.
• Cleaning: 17 inches of open circle at 28 inches means a whole arm and a brush reach the wall and most of the cone without a lance. On a vessel that changes product, that access is the feature that keeps the changeover honest.
• Ratings and limits: a specific gravity rating of 1.9, 125 pounds of water at 15 gallons, 238 pounds of max contents, and 100 F / 37 C. The sheet publishes no cone angle, no stand and no warranty term.

Where anything is eventually mounted over or beside the rim, decide the layout once on paper instead of drilling twice: the top fitting placement guide sets out how fill, level and drain are arranged so they do not fight each other. Name the product when you order, because on an open vessel the chemistry decides the wall, the support and what belongs in the room with it.

Bench batching, make-up and rinse-down duty

An open top at 15 gallons is bought by anyone who has to get at the contents: dilution and make-up stations where a concentrate meets water, laboratory and pilot batching, parts washing and small soak or dip work, plating and finishing shops running a working bath, greenhouse and nursery feed mixing, brewing and food plant cleaning stations, aquaculture and live holding at small scale, and the mop-out or rinse tank at the end of a line. The thread through all of it is that a person works over the rim, which is why the 28 inch height and the 17 inch opening are the two specifications to check against the people who will actually use it, before the gallons are checked at all. The second thing worth planning is what the vessel sits on, because an open tank that has to be tipped, dragged or lifted to empty it is an open tank that gets spilled. Build the support so the cone discharges into whatever collects it, and the duty takes care of itself.

Nine pounds out of Lincoln, Nebraska

One plant is listed for this part: Lincoln, Nebraska, with Nebraska in the ships-from field, so there is a single lane to quote and it runs from the plains. The freight class is given as 300 on an LTL mode, and the shipping size matches the tank at 17 inches long by 17 inches wide by 28 inches high. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. Nine pounds is a one-hand carry, so nothing needs booking at the receiving end, and that is worth remembering when the tank arrives before the support does. An open vessel is also the one most likely to arrive with something in it that should not be there, so look inside before you lift it and rinse it before it is set. Build and level the stand, put the tank into it, then fill it with clean water and hold that 125 pound load while you read the cone, the seat it sits in and the ground under the whole arrangement. Because there is no lid on this vessel, mark the intended contents on the outside of the shell before the first batch and keep something over the top between shifts; what ruins an open tank is almost never the liquid somebody put in it on purpose. Photograph the cone from below before anything is plumbed to it, so a slow weep later is something you can compare against rather than argue about. Write the outlet fitting size and material on the site plan; the replacement is ordered by those two words.
