Snyder Industries 30 Gallon Plastic Horizontal Leg Tank in White

Who buys the heavier rating in the smallest tank on the sheet

Buyers come to this part with a liquid in mind rather than a vehicle. A co-op or an applicator carrying a concentrate rather than water. A plant moving a heavier process liquid between buildings on a cart. A municipal or utility crew with a dosing chemical that has to travel to a site. A pest control operator running an applicator tank on a truck, filled with a mix that is heavier than water. A wash contractor carrying a concentrated detergent to the job instead of a diluted drum of it. For all of them the 1.9 rating on this sheet is the specification being bought, and the 475 pounds of max contents is what that rating is worth in a 30 gallon shell: nearly twice what the tank weighs full of plain water, in the same 30 gallons. Buy on the rating that matches the liquid and never on the assumption that a bigger tank must be a stronger one. The rest of the discipline is ordinary leg tank discipline and is worth spelling out because a good wall on a bad mounting still fails at the legs. The tank bears along the full length of its legs on a flat, continuous surface: a bed floor, a skid with a solid deck, a bench, a pad. No gap under the middle, no leg over an edge, nothing wedged under one end to level it, no through-bolt in a leg. Strap over the body at both ends. Twenty inches of length is the shortest body in this family, which makes it the one that fits where a toolbox has already taken the space, and at 12 pounds empty it is the lightest listed here. Put your actual draw and refill interval through the tank sizing calculator before buying two trips a day by accident, and take the thermal freeboard from the tank sizing guide.

The 1.9 rating in the shortest body, against the lighter rating beside it

Two tanks on this sheet hold 30 gallons and the choice between them is a wall decision, not a volume one. This part is rated at a specific gravity of 1.9 with 475 pounds of max contents; SII-1080000W94301 is rated lighter and carries less max contents, in a square 23 by 23 inch plan rather than this 20 inch one. Both are 23 inches wide, both stand 26 inches, both carry a 6 inch lid, both are listed at 250 pounds full of water, and both ship from the same four plants. So the question to answer before ordering is what the liquid weighs, and the answer decides the part number. Where the load is water or something close to it and the square footprint is the constraint, the other part is the better buy and we would rather say so. Where the load is heavier than water, this is the one. The third row is the same family in a longer body: SII-1060000N45 doubles the gallons while keeping this exact 23 inch width and 26 inch height, so a rack, a strap set or a shelf built around this tank takes the 60 gallon tank without a change, at 23 pounds empty instead of 12. That is the upgrade to plan for if the refill interval turns out shorter than you expected.

The pump path off a 26 inch body, and the 6 inch lid above it

• Start with what is not on the sheet: there is no outlet field and no inlet field on this record, so we print no fitting size, no thread and no valve. Tell us how the tank is going to be drawn down when you order and we confirm what your part carries before it leaves.
• Pump placement: on a body only 26 inches tall the pump belongs below the tank, as close in as the mounting allows, with the hose falling toward it and the first bend well clear of the tank wall. Standing liquid is the only thing keeping a suction flooded at this size, and there is not much of it.
• Prime and protection: use a self priming pump or a foot valve, put a strainer where a hand can clean it without breaking the line, and fit a run-dry stop. A 20 by 23 inch floor empties quickly at the end of a draw and a pump that pulls air once will do it again.
• Filling: a 6 inch lid on top, which is a hose fill rather than a bucket fill and a narrow window for cleaning. Plan the wash-out routine around the opening the sheet gives rather than the one you would like it to give, and keep the lid closed while the vehicle is moving.
• Breathing: keep the vent path clear whenever a pump is drawing. A closed tank and an open pump is how a wall gets pulled in, and it does not take 30 gallons of vacuum to do it.
• Service limit: 120 F / 48 C, the only limit this sheet publishes.

A heavier rating changes what the tank will hold; it does not change what the plumbing owes it. Flexible connector at the first joint, valve carried on its own bracket, nothing rigid clamped between the tank and the vehicle frame. Name the liquid when you order and the fitting, gasket and bolting are matched to it. Where the liquid is regulated and a second wall is part of the conversation, the Snyder Captor SPCC 40 CFR 112 walkthrough works through what containment actually buys and what it costs in usable volume.

Chemical carries, applicator work and yard duty

The work this part is specified for is the work where the liquid is heavier or harder than water: concentrate transport for custom application, dosing chemical carried to a remote site by a utility crew, sprayer and applicator duty for a pest control operator, concentrated detergent for a wash contractor, process liquid moved between buildings on a plant yard, and top-up supply on a maintenance round. Before a loaded tank goes on the road behind a farm vehicle, know exactly what the exemption does and does not cover: the 49 CFR 173.5 agricultural exemption article states the scope instead of implying it covers every trip a farm truck makes. For the comparison between leg tanks, loaf tanks and applicator tanks on the same deck, read the applicator and leg tank guide.

A 20 inch shipment that the sheet moves at a parcel class

This part is listed at Chowchilla, California; Lincoln, Nebraska; Marked Tree, Arkansas; and Philippi, West Virginia, so there is usually a plant within a short lane of wherever it is going. The sheet gives the freight class as UPS under NMFC 156600 and gives no numeric class; we print the field as it stands. It shipments at 20 by 23 by 26 inches, which is the smallest shipment in this batch. Price the lane to your ZIP with the freight cost estimator, and note that the listed price is before freight. At 12 pounds this is a one-hand lift, and that is its own hazard: a tank this light will slide across a bed before it is strapped, so have the straps or the rack ready on the day it arrives rather than the week after. Water-fill it on level ground, look along the legs for contact and at the 6 inch lid for weeping, then drain it dry before the working liquid goes in. Take the tare weight on a scale before the first fill; on a tank rated for a heavier liquid, knowing the empty weight is how you check what is actually inside it later. Keep the first delivery's paperwork with the tank; strength and date on day one is the baseline for every batch after.
