Snyder Industries 200 Gallon Plastic Chemical Feed Station Tank

The linear-wall 200 against the rest of the 200s

Start with the family, because that is where this purchase is actually decided. The sheet puts four 200 gallon stations in front of you and they differ in exactly two ways: the wall material and whether a stand comes with the tank. This one is the linear polyethylene wall on the short body, 57 inches tall and 198 pounds. SII-5720103CF42 is the same 76 by 62 by 57 inch shell at the same 198 pounds in a cross-linked wall. SII-5720104CFWS42 and SII-5720104CFWS45 are listed at 74 inches and 242 pounds on the same plan, which is the stand. So the question to answer before ordering is a two-part one: does the chemistry or the handling argue for a cross-linked wall, and does the pump need the tank lifted. If the answer to both is no, this is the part to buy, and it is the shortest and lightest way to put 200 gallons of day supply on a floor. What it asks of the site is a flat, level, continuous bearing surface under the whole 76 by 62 inch base: a poured pad, a housekeeping slab, a steel plate, not two rails with air under the middle and not a floor that falls away at one corner. Above that base sits 1,668 pounds when the station is full of water and 3,169 pounds at the rating, which is what the floor and any containment kerb are carrying. Put your dosing rate and delivery interval through the tank sizing calculator before you settle on 200 gallons, and take the freeboard a warm or gassing liquid needs from the tank sizing guide. Where a secondary containment argument is being had on site, the Snyder Captor containment comparison sets out what a second wall buys and what it costs in usable volume.

One shell, four ways to buy it

Read the table as two questions rather than six products. The first two rows are the same 76 by 62 by 57 inch shell at the same 198 pounds, and the sheet separates them by wall material alone: this part is the linear polyethylene one. The next two rows are the same plan at 74 inches and 242 pounds, and the difference is that they arrive standing. The 250 gallon SII-5730103CF42 is the step up and it is the cheapest capacity increase in the group in floor terms, because it keeps the same 76 by 62 inch plan and pays for the extra gallons in height, 69 inches against 57, and in weight, 209 pounds against 198. The last row is in the family list but not in the family: SII-6370424N95402 is a Flowmaster dry hopper bin recorded at 25 cubic feet and 190 gallons, 48 by 48 by 57 inches and 330 pounds, built for dry material through a hopper. We list it because the sheet does, and this page claims no liquid duty, no chemical service and no rating for it.

Headspace, a 14 inch lid, and what the sheet does not name

• Breathing: the sheet publishes no vent fitting on this station, so the 14 inch lid is the only opening it gives and the headspace above 200 gallons is the only air volume you have to work with. A day tank that is filled fast and drawn down fast moves that air in both directions, and the lid is where it has to go. Do not seal it and then run a pump; a closed top with a pump pulling underneath is how a polyethylene wall gets drawn in.
• The opening itself: 14 inches is wide enough for a fill line, a level device and a hand, and narrow enough that it will not take a shoulder, so plan cleaning and inspection around it rather than around the opening you would like. At 57 inches the lid is at chest height on a level floor, which is the easiest fill height in the group.
• Outlet and drain: this sheet lists no outlet size and no inlet size. We will confirm the fittings on your part before it ships rather than printing a size the sheet does not carry. What holds regardless is the layout: the pump sits below the low point on its own base, with a short falling run into the suction so the column above keeps it flooded.
• Level and identity: the level goes on a gauge read from where the operator stands, and the chemical goes on the tank in words. The level gauge selection guide compares the technologies for chemical service, and the tank label and signage guide covers the marking that survives an inspection.
• Service limit: 120 F / 48 C, the only limit this sheet publishes, and there is no warranty term on it.

Everything downstream of the tank is carried on its own support, never on the station itself, with a flexible connector at the first joint so a pump start is not taken into the wall. Tell us the chemical when you order and the fittings, gaskets and bolting are matched to it rather than left generic.

Where a 200 gallon day tank earns its keep

Two hundred gallons is the size a plant lands on when drums are too small and a bulk tank is too much: hypochlorite or caustic at a small water or wastewater works, a polymer or coagulant day tank beside a clarifier, cooling tower treatment at a campus plant, bulk detergent behind a wash bay, a plating or finishing line feeding from one station. Every one of those depends on knowing what is actually in the tank at the moment it is dosed, and a sample drawn carelessly gives a wrong answer that reads like a right one, which is what the chemical sampling protocol article is about. Draw from the same point, at the same depth, on the same cadence, and log it.

Marked Tree to your dock at 198 pounds

This station is molded at Marked Tree, Arkansas, and that single plant sets the lane. The sheet gives the freight class as LTL under NMFC 156600-02, and it moves shipping at 76 by 62 by 57 inches, which is a pallet and not a parcel. The freight cost estimator prices the lane to your ZIP, and the listed price is before freight. At 198 pounds take it off the truck with a forklift or a pallet truck under the base, never by the lid. Set it on the finished, level pad before anything is plumbed, then fill it with clean water, hold it while you read the base, the lid seal and the floor under it, and drain it dry before the chemical arrives. Write the chemical name on the station before the first delivery, because the station nobody can identify at a glance is the one that takes the wrong load. Write the outlet fitting size and material on the site plan; the replacement is ordered by those two words.
