Ninety gallons lifted to 57 inches on its own stand
The Snyder SII-5690104CFWS42 is a 90 gallon chemical feed station tank supplied on a stand: cross-linked polyethylene, white, 56 inches long, 43 inches wide and 57 inches tall overall, weighing 123 pounds as it is listed. The plan is the same 56 by 43 inches as the floor-standing stations in the family; the height and the weight are where the stand shows up. The sheet rates the wall at a specific gravity of 1.9, giving 751 pounds for 90 gallons of water at 8.34 pounds per gallon and 1,426 pounds of max contents. It gives a 14 inch lid, no outlet, no inlet and no warranty term, and one service limit at 120 F / 48 C. Molded at Marked Tree, Arkansas, LTL under NMFC 156600-01.

The stand under it, and the floor that carries it
The reason this part exists is the space underneath the tank. A floor-standing station puts its base on the concrete; this one stands the same 56 by 43 inch vessel on a frame so the bottom of the tank is clear of the floor, and that clearance is what a metering pump wants. With the tank above the pump, the suction is flooded and the pump primes itself at every start instead of pulling a lift out of a vessel that is emptying. The same clearance lets a drain run into a carboy or a sump without a transfer pump, and it means a leak shows as a drip you can see rather than a stain you find with a boot. The floor still has to do the work. Set the stand on level, finished, continuous concrete or a poured pad that carries the whole frame, get it level before anything is plumbed, and anchor it if the room or the site says so. Above that frame is 751 pounds of water at full and 1,426 pounds at the specific gravity of 1.9 the sheet rates, and it is all standing higher than it would on a floor-mounted tank, so the base has to be flat and the tank has to be plumb. The sheet publishes no load rating for the stand, no leg count and no anchoring detail, so this page claims none of them; ask us and we will put Snyder's own guidance for the stand in writing. Check the working volume first: 90 gallons against your dose rate and delivery interval in the tank sizing calculator, with the freeboard for a warming chemical from the tank sizing guide. And where the room needs containment around the station, the Snyder Captor containment and SPCC comparison is where an integral second wall and a bunded room get compared instead of assumed.
With the stand at 57 inches, without it at 41
| Part | Gallons | Length x width x height | Empty weight |
|---|---|---|---|
| SII-5690104CFWS42 (this one, cross-linked, on a stand) | 90 | 56 x 43 x 57 in | 123 lb |
| SII-5690104CFWS45 (on a stand, second part number) | 90 | 56 x 43 x 57 in | 123 lb |
| SII-5690103CF42 (cross-linked, no stand) | 90 | 56 x 43 x 41 in | 99 lb |
| SII-5690103CF45 (high density linear wall, no stand) | 90 | 56 x 43 x 41 in | 99 lb |
| SII-5680023CF42 (smaller, narrower plan) | 60 | 47 x 36 x 58 in | 108 lb |
| SII-5700103CF42 (larger, same plan, no stand) | 120 | 56 x 43 x 51 in | 130 lb |
The decision this table settles is whether you are buying the height. All four 90 gallon parts hold the same volume in the same 56 by 43 inch plan; the two on stands are listed at 57 inches and 123 pounds, and the two without are 41 inches and 99 pounds. Buy the stand when a pump has to live under the outlet, when a drain has to reach a container, or when somebody has to be able to look under the tank during an inspection. Buy the floor-standing version when the ceiling is low, when the fill point is fixed at a height the stand would overshoot, or when the pump is already set below floor level in a pit. SII-5690104CFWS45 is listed at the same 56 by 43 by 57 inches and the same 123 pounds as this part, so the sheet gives them as the same station under two numbers and we print that rather than inventing a distinction; order whichever number your drawing already carries. The 60 gallon SII-5680023CF42 is the one to look at when the floor is the constraint rather than the volume, at 47 by 36 inches and 58 inches tall for 108 pounds, and the 120 gallon SII-5700103CF42 is the floor-standing step up that keeps this plan at 51 inches and 130 pounds. None of the four 90s is a better tank than the others; they are the same tank at two heights in two walls, and the site decides.

A flooded suction under the tank, and a 14 inch lid above it
- Outlet and valve: no outlet and no inlet appear on this sheet, so this page names no fitting size and no valve type. Tell us the chemical, the flow and the pump you are feeding, and the fitting arrangement for your part is confirmed in writing before it ships.
- What the stand is actually for: the pump goes below the tank on its own base, with a short falling run into the suction, so the standing liquid keeps it flooded through a batch. That layout is worth protecting when the pipework is designed, because every elbow and every inch of lift you add under there gives back the advantage you paid the stand for.
- Protection: an isolating valve at the tank, a cleanable strainer ahead of the pump, and a low-level cut-out that stops the pump with liquid still above the take-off. A metering pump run dry on chemical duty is a maintenance call and sometimes a whole shift.
- Filling and access: a 14 inch lid on top at 57 inches, which is chest height for most people and a comfortable fill from a hose coupling at working level. Keep it closed except when filling and keep an air path open, because a sealed tank over a running pump collapses inward.
- Service limit: 120 F / 48 C, the only limit this sheet publishes, and there is no warranty term on it.
Support everything below the tank from the floor rather than from the frame, and break the first joint with a flexible connector so pump pulsation is not fed into the vessel. Fit the level device for the chemistry in the tank; the level gauge selection guide for chemical service compares radar, ultrasonic, hydrostatic and magnetostrictive against real chemical conditions rather than a datasheet. Then mark the station properly, because a raised tank is usually part of a row of them and the labelling is what stops the wrong delivery going into the wrong lid: the tank label and signage guide sets out a marking scheme that holds up under inspection.
Metering pumps, day tanks and the chemistry that has to be labelled
A station on a stand is bought where dosing is the job and the pump must not lose prime: hypochlorite, caustic, acid or polymer feed at a water or wastewater plant; a day tank beside a line in a food, paper or metal finishing plant; cooling water treatment on a plant roof or in a basement; bulk chemistry at a wash, a laundry or a plating shop; a small dosing skid at a mine or a generating station. All of those depend on knowing what is in the tank right now, which is a sampling discipline rather than a gauge reading. The chemical sampling protocol for bulk polyethylene storage explains where to draw from, how often by chemistry class, and the mistakes that produce a laboratory result that is wrong and looks right.

A taller shipment on the same Arkansas lane
This part ships from Marked Tree, Arkansas like the rest of the family, but it travels as a taller unit: 56 by 43 by 57 inches at 123 pounds, and the sheet gives it its own NMFC of 156600-01 where the floor-standing stations read 156600-02. The freight class is given as LTL. Price the lane to your ZIP with the freight cost estimator, and note that the listed price is before freight. Check the doorway and the ceiling on the route before the truck is booked, because a station on its stand is nearly five feet tall on the pallet and a chemical room door does not always oblige. Take it off with a forklift under the pallet, set the frame on its finished, level floor, and get it plumb and stable before a single line is connected. Water-fill it once, hold it, and look at the frame footings, the lid seal and the floor underneath before the chemical arrives. Then take a photograph of the finished installation with the pump in place beneath the tank, because that picture is what settles the argument the first time somebody asks why the pump is down there. The first fill is the only cheap time to find a problem, so do it in daylight with someone watching the base.
