Snyder Industries 200 Gallon Open Top Tank with Loose Cover and Protective Wrap

Where a thirty-six inch circle of floor carries sixteen hundred pounds

Start with the floor, because on a tank this shape the floor is the whole structural argument. Thirty-six inches across and 53 inches tall is a tall, narrow cylinder: three feet of plan holding a column of liquid that stands a little under four and a half feet. That proportion is what lets this tank stand in a corner, in a bay, beside a bench or in a row of identical vessels without eating a room, and it is also what makes the support under it matter more than it would under a squat tank. Set it on a flat, continuous, level surface that carries the whole 36 inch base. Not on two rails. Not shimmed at one point. Not on a pallet with a broken deck board, because a plastic base that bridges a gap will find that gap every time the tank is filled. Above that base the sheet gives 1,668 pounds of water and 3,169 pounds at the rating, and all of it lands inside a circle you could step across. Where that circle is an outdoor slab or a new pour rather than an existing plant floor, the concrete pad sizing guide for above-ground polyethylene tanks sets out the framework and where its boundary lies. The second half of the siting question is what happens over the top. An open top vessel is reached into, dipped, skimmed, scooped, hosed out and looked at, which is the reason people buy one, and at 53 inches the rim sits at about chest height on most adults. That is a comfortable height to work over and a poor height to lift a heavy scoop out of, so think about what actually comes out of this tank and whether a step, a platform or a lower vessel serves the operator better. It also means the contents are open to the room: to dust, to splash, to rain if it stands outside, and to anything that falls in. The loose cover named on this sheet is there for that, and nothing here says it does more than sit on the opening. Size the volume honestly before the footprint gets committed. Run your batch and turnover through the tank sizing calculator, and take the freeboard discipline from the tank sizing guide, because a vessel that gets agitated, hosed or filled by hand needs the top few inches that a sealed one does not. Where the duty is standing water held for an emergency rather than working stock, the fire-water reservoir design guide works through the sizing discipline and the cold weather engineering that duty brings with it.

One seventy-five, two hundred, two fifty

Three tanks, and the geometry tells you almost everything about which one belongs in your room. SII-1550200N39 is the odd one out and the interesting one: 175 gallons on a 42 inch plan only 30 inches tall at 75 pounds. That is a wide, low tub, rated by its own sheet at 1.35 rather than this tank's 1.9. Twenty-five gallons less than this tank, six inches wider each way, and 23 inches shorter, which puts the rim at about waist height. If the work is done by hand over the top of the tank, if the ceiling is low, or if a person has to reach the bottom without a ladder, that shape wins and it is not close. SII-573TDVOT-45 goes the other way on the identical 36 inch plan: 250 gallons at 68 inches tall and 79 pounds. Fifty more gallons on exactly the same floor space, bought with 15 more inches of height. Where floor is the thing you are short of and the tank is filled and drawn off rather than worked over, that is the better buy, with the caveat that 68 inches puts the rim above chest height and changes it from a vessel you reach into to a vessel you pump out of. This tank sits between them on purpose. Same footprint as the tall one, a working height most people can still see into and get an arm over, and the heaviest empty weight of the three at 85 pounds. Decide it on the work, not the volume: if hands go in the tank, go short and wide; if only hoses go in, go tall.

No outlet on the sheet and a drain you have to plan

• The outlet: this sheet publishes no outlet, no inlet, no bulkhead and no valve, so no size, thread or position is claimed here. That is the first thing to settle when you enquire, because it decides whether the tank is emptied by a pump through the top or by a fitting at the bottom, and those are two different installations. Tell us the liquid, the line size and how the vessel gets emptied, and we will confirm what this part number carries before anything is ordered.
• Draining by hand: with no published bottom fitting, the honest working assumption on a 53 inch open vessel is a suction line dropped over the rim to a pump on the floor. Keep the strainer clear of the base so the last settled inch is not the first thing the pump lifts, and clamp the hose to a fixed point so the tank rim never carries its weight.
• Anything you do add hangs on its own steel: a valve, a sight arrangement or a pump is carried on a frame or a wall, not on the tank. At 3,169 pounds of max contents the wall has its own job.
• The opening: 40 inches, given on the sheet as both the lid size and the manway. That is a wide mouth on a 36 inch tank, which is what makes it genuinely cleanable and genuinely inspectable, and it is the whole reason to choose an open top over a closed one.
• The cover: the name gives a loose cover and a protective wrap. Loose is exactly what it says. No seal, no gasket and no vent is published, and none is claimed here, so do not plan on this tank holding a vapour, excluding an atmosphere or keeping out a driving rain.
• Limits: 120 F / 48 C, a specific gravity rating of 1.9 given as 1.9 (Max 15.87 lbs/gal), and no warranty term on this sheet. That is the extent of what it publishes.

Name the liquid when you order. On an open vessel the exposure is at the top as well as the wall, and the fitting we add, the cover arrangement and the material all follow from what is actually in it.

Batching, rinsing and the vessel people reach into

Two hundred gallons in an open cylinder is a shop and plant workhorse rather than a storage vessel: solution make-up beside a dosing pump, rinse and dip stations in a metal finishing or plating shop, a wash and soak tank in a parts room, quench and cooling duty beside a small machine, holding for wash water and process water that will be pumped away, polymer and nutrient mixing on a nursery or greenhouse bench, and general stock holding for a liquid nobody wants to keep in drums. The tell is always the same: somebody has to see the level, put a hand or a tool in, and clean it out afterwards. That is what an open top is for, and it is why the 40 inch opening matters more than any other number on this sheet. The same shape does second duty as a catch or transfer vessel where a bigger tank feeds it and it feeds something else. Where it stands outdoors, remember what the cover is and is not: the sheet gives it loose, so rain, leaves and sun are part of the installation and belong in the plan rather than in a footnote.

Marked Tree, Arkansas at eighty-five pounds

This tank is moulded at Marked Tree, Arkansas, and the sheet lists Arkansas as the state it ships from, which puts the mid-South and the lower Mississippi valley on a short lane and the coasts on a planned one. The freight class is LTL under NMFC 156600-03, and it shipments at 36 by 36 by 53 inches. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. At 85 pounds two people take it off a tailgate and one person with a hand truck moves it across a shop, so there is no forklift to book and no dock appointment to make. Take it by the body and never by the rim of the opening. Check the cover and the wrap against the packing list the day it arrives, because loose items are the ones that go missing between the trailer and the store room. Set it in its final position on level support before you fill it, then fill it with clean water and hold that 1,668 pound load overnight while you read the base, the seam and the floor under it. Look at the floor as carefully as you look at the tank; on a three foot base, a soft spot shows up as a tilt long before it shows up as a leak. Mark the level you filled to on the outside wall in paint marker, and keep that mark as the reference every later check is read against. A photo of the tank on its pad, full, on day one is worth keeping; it is the baseline every later inspection is compared against.
