Snyder Industries 535 Gallon Plastic Horizontal Leg Tank

Low and long: the skid and the low clearance haul

Height is the constraint this tank answers. The buyers are the ones who have to get under something or stay under something: a farm hauling a nurse tank through a machine shed door or under a grain leg, a poultry or hog operation running a wash tank between low buildings, an applicator whose trailer has to go under an irrigation pivot or a tree line, a plant yard with a covered loading bay, a utility crew with a low garage. Fifty-two inches of body is four feet four inches, and on a trailer deck that difference between fifty-two and fifty-six inches is often the whole argument. The second thing the shape buys is roll behaviour: 78 inches of length and only 47 inches of width, sitting low, means the loaded mass is spread fore and aft along the deck rather than stacked up over the axle, and a long low tank rides a side slope better than a short tall one holding the same volume. What it costs is deck length. Six feet six inches of tank does not fit a short bed, and the narrow 47 inch width means a cradle or saddle built for a 49 inch body will not sit right, so build the mounting for this tank rather than adapting the last one. The legs bear along their full length on a flat, continuous surface with no gap under the middle, no leg over an edge and nothing bolted through a leg. Strap over the body at both ends and take the load against a headboard: there is 4,462 pounds of water above those legs when it is full, and 8,478 pounds at the rating. Check 535 gallons against your draw and your refill trip in the tank sizing calculator, and take the reserve and the freeboard from the tank sizing guide. Where the load is a blend, a long shallow body layers in its own way and the fertilizer-blend tank stratification article is where that gets worked through properly.

535 in white and black, the 525 below it and the 730 above

The choice inside the shell is colour and nothing else. SII-1400300N51 is listed at the same 535 gallons, the same 78 by 47 by 52 inches and the same 124 pounds in black, and the sheet explains no further, so we print that and say only what a black wall is chosen for: keeping daylight off the load. Below it, SII-1400000N45 holds ten fewer gallons in a body three inches shorter, an inch wider and an inch taller at the same listed 124 pounds, with a 10 inch lid instead of this tank's 18 inch one, so the trade against this tank is a shorter deck against a smaller opening. Above it, SII-1360000C26 is the one product in this group Snyder names after its securing device: a 730 gallon leg tank with a securing hoop, 80 by 54 by 57.5 inches and 240 pounds. That is two hundred more gallons for seven inches of width, five and a half inches of height and nearly twice the empty weight, and the hoop belongs to that part rather than to this one, which carries no hoop on its sheet and is claimed none here. Buy this tank when 535 gallons has to ride low and long with a lid you can get an arm through.

An 18 inch lid at 52 inches, and a 2 inch low point

• The drain path: a 2 inch outlet at the low point, as the sheet lists it, which is the size that empties 535 gallons through a transfer pump in one pass instead of three. Pump below the outlet, short falling hose, first bend clear of the fitting; the 52 inch body is the lowest in this group so there is no head to waste.
• Prime on the lowest body here: self priming pump or a foot valve, a cleanable strainer within reach, and a run-dry stop. Seventy-eight inches of floor means the last of a load spreads thin and leaves a suction sooner than the level suggests.
• Gravity draining: park with a fall toward the outlet end and a full-flow shutoff at the fitting will empty the body without the pump. Flush in the same attitude before a product change, and keep a second valve downstream for hose work.
• Filling and cleaning: an 18 inch lid at 52 inches, which is the best combination in this batch for a person who has to open, fill and wash out a tank: a wide opening at a height reachable from the deck without a ladder. Keep the vent path clear, and the lid closed while the vehicle moves.
• Service limit: 120 F / 48 C, the only limit published on this sheet.

The narrow body is the detail to respect in the plumbing. At 47 inches wide with a long span, the mounting takes more of the road input than a short tank does, so the first joint off the outlet is flexible, the valve sits on its own bracket off the deck, and the saddle follows the body along its length rather than pinching it at two points. Name the liquid when you order and the outlet fitting, gasket and bolting are matched to it. Where the load is regulated and somebody has raised containment for the yard the tank sits on, the Snyder Captor SPCC 40 CFR 112 walkthrough works through the trade honestly.

Under the pivot, through the shed door

This shape goes out for nurse and applicator supply where the route has a height limit, wash and flush water in livestock and poultry operations, transfer duty on a plant yard with a covered bay, water for dust control on a low-clearance site, and general portable supply on a long skid that lives on a flatbed. When the choice between a leg tank, a loaf and an applicator body is still open, the applicator and leg tank guide compares them against the duty, which is the comparison worth making before the deck is drilled.

Resin compatibility, line by line

Below are the liquids this resin is rated for, the concentration each rating holds to, and the fitting and gasket to specify. Check the exact concentration and temperature you run against the chemical page or the chemical compatibility database before ordering.

• DEF (32.5%) is a clean fit and a common haul load, but it needs 316SS fittings and EPDM gaskets - not PVC - so do not carry it over from a wate
• Aluminum Sulfate (50%, PVC, EPDM)
• Calcium Chloride (40%, PVC, EPDM)
• Magnesium Chloride (30%, PVC, EPDM)
• Ferric Chloride (50%, PVC, EPDM) and
• Urea Solution (50%, PP/PVC, EPDM). Acids generally need Viton gaskets -
• Hydrochloric Acid (37%, PVC, Viton)
• Phosphoric Acid (85%, PVC, Viton)
• Hydrofluoric Acid (48%, PP/PVC, Viton) and
• Sulfuric Acid (98%, CPVC, Viton) - as do
• Sodium Hypochlorite (under 16.5%, PVC, Viton) and
• Hydrogen Peroxide (50%, PVC, Viton). Aggressive oxidizers such as
• Peracetic Acid (30%) call for 316SS fittings with Aflas gaskets. Other charted matches include
• Acetic Acid (60%, PP/PVC, EPDM)
• Ferric Sulfate (60%)
• Ferrous Sulfate (20%)
• Ethylene Glycol (100%)
• Propylene Glycol
• Sodium Carbonate (30%)
• Potassium Carbonate (50%)
• Potassium Hydroxide (saturated)
• Sodium Bisulfate
• Sodium Bisulfite
• Sodium Thiosulfate (40%)
• Hydrofluosilicic Acid (26%, PP/PVC, Viton)
• Polyaluminum Chloride and
• Zinc Orthophosphate ozonated water up to 10 PPM is also charted. Verify every selection against our

The longest tank in this group on an Arkansas lane

The SII-1400300N45 is molded at Marked Tree, Arkansas, the short lane into the Mid-South and the lower Mississippi valley. The sheet gives the freight class as LTL under NMFC 156600-02 and it crates at 78 by 47 by 52 inches, six and a half feet long on the pallet, so the receiving end needs the room to turn it as well as the machine to lift it. The freight cost estimator prices the lane to your ZIP, and the listed price is before freight. Take the 124 pounds off with forks under the legs, never by the lid and never by the outlet, and set it on the finished deck or skid before anything is plumbed. Fill it with clean water on level ground, read along all the legs for contact and at the 18 inch lid and the 2 inch fitting for weeping, then drain it dry. Measure the loaded height at the tallest point of the finished installation and write that number on the vehicle, because this tank was bought to get under something. Keep one spare gasket for the outlet fitting on the shelf; it is the part that fails on a holiday.
