Snyder Industries 1650 Gallon Plastic Horizontal Leg Tank with Securing Hoops

The hauler's case for 3 inches of outlet on 1650 gallons

Ask who needs to empty a tank fast, and you have the buyer for this part number. A bulk hauler filling at a plant and discharging at a yard, where time on the pad is the cost. A custom applicator transferring a full load into a sprayer between fields rather than metering it out through a boom. A co-op or terminal moving fertilizer solution from a nurse tank into a rig. A drilling, road or right-of-way crew dumping water where it is needed and driving back for more. A municipal operation offloading brine or flushing water into a truck or a basin. A plant taking a delivery into a day tank and pushing it on to a process line at line rate. All of those are transfer duties rather than dispensing duties, and 3 inches of outlet is what separates them from a tank you draw a pail from. That is the reason this part number exists beside its twin, and it is the first thing to check against your own pump and hose before anything else on the sheet. The rest of the installation follows from the size. Eleven feet ten inches of length and five feet eleven inches of width means the deck or the floor has to be flat and continuous under the whole body, because a rotationally molded tank bears on every part of the surface it touches and nothing else; a proud crossmember, a raised board or a hollow in a slab becomes the bearing point for 13,761 pounds of water, or up to 26,146 pounds of contents at the sheet's rating. Put plywood or a mat under it on a ribbed deck and let it bear evenly. Then design for surge, because at this length and width the wave is the biggest load the mount will ever see and it peaks at part-full, not full: restrain the tank fore, aft and across, through its own structure, with anchor points you inspect as often as the tank. The sheet names this part number with securing hoops and publishes no hoop dimension, count or rating, so this page describes no hoop function and no mounting method that depends on one; if your mount is being engineered around them, ask us and we will get the detail from Snyder in writing. How a leg or applicator tank is classified once it travels is set out in the applicator and leg tank classification guide, with the portable utility case in the loaf-style portable utility tank guide. Check 1650 gallons against your real load cycle in the tank sizing calculator, with the reserve and freeboard from the tank sizing guide.

Two hooped 1650s, and the outlet that separates them

The tank to compare this one against is its own twin. The SII-1000700N45 is the same 1650 gallons in the same 142 by 71 by 55 inch shell at the same 533 pounds, and the sheets give them different outlets: 3 inches here and a smaller one there. That single difference is the whole buying decision between them, and it is a real one. Take this part number when the job is to move a load in and out quickly, when a transfer pump is already sized for a larger suction, or when gravity discharge into a truck or a basin is the way the liquid leaves. Take the twin when the liquid is metered through a boom, a line or a valve and a bigger port buys you nothing. Beside the pair, the sheet lists two tanks that are close in volume and nothing like it in shape. The SII-10034 is named a super nurse tank with a center sump, 1615 gallons at 140 by 69 by 61.25 inches and 509 pounds; the sheet publishes no sump dimension, so this page describes none, but it is six inches taller than this shell and worth asking about if your discharge is from the middle of the body rather than the end. The SII-1460000C26 goes the other way entirely: 1685 gallons stretched to 159 inches on a 48 inch width and only 480 pounds, which is the buy when the deck is narrow and long. Between them, the reason to take this tank is a wide body, a low height and the largest outlet on the sheet.

Pump suction through 3 inches, and where the last gallons go

• The pump: a 3 inch outlet is only worth having if the suction side is built to match it. Size the pump and the hose to the port rather than to habit, mount the pump below the fitting and forward of it on the deck, and give it a short falling run into the suction with as few elbows as the layout allows. Done that way the column keeps the pump flooded to the last inches of a 55 inch body; done the other way, with the pump lifted level with the fitting, a larger outlet just loses prime faster.
• Prime and protection: a strainer that can be cleaned without breaking the line, a full-bore shutoff valve between the tank and the pump so a hose change is not a tank drain, and a run-dry cut-out, because on a transfer duty the operator is watching a truck rather than a level.
• Outlet: a 3 inch outlet, as the sheet lists it, the largest in this family. It is a transfer port rather than a metering port, and the mistake to avoid is hanging a rigid line off it because the pipe is big enough to be stiff. A flexible connector at the first joint, always, and the first valve carried on its own support off the deck rather than off the tank wall.
• The last of it: a body eleven feet ten inches long and under five feet tall leaves its residue across a broad floor. Level leaves it there; a deck shimmed or parked with the outlet end downhill does not. On a transfer tank that is the difference between a rinse and a cleanout.
• No inlet on this sheet, so none is asserted: filling is through the 18 inch lid, with the hose down inside the body. Keep the lid closed in transit and keep its vent path clear, because a tank drawn on hard through a blocked vent will pull its own wall in, and at 71 inches of width there is a lot of wall to lose.
• Service limit: 120 F / 48 C, as the sheet gives it, covering the liquid and the tank standing in the sun.

Tell us the liquid at order and we will match the outlet fitting, the gasket and the valve material to it against Snyder's current documentation rather than guessing at the counter. Where the liquid is a blended fertilizer solution, the thing that will bite you is the blend and not the tank: a wide shallow horizontal body has plenty of surface and very little height to drive mixing, and a stratified load will run a spreader off spec before anybody notices, which the fertilizer blend stratification guide works through with the field checks that catch it. Where site rules require secondary containment, a single-wall leg tank does not provide it, and the Captor double wall containment walkthrough sets out what a contained installation has to do to count. In winter, drain the valve, the outlet and the hose and leave the body to look after itself.

Bulk hauling, fertilizer solution and water supply at trailer scale

Sixteen hundred and fifty gallons on legs is a load rather than a supply, and the duties reflect that. Bulk hauling of fertilizer solution, carrier or fluid feed between a plant and a field. Nurse duty on a trailer feeding a sprayer through a day, with the load transferred rather than metered. Water hauling in quantity to livestock, a remote building, a planting crew, a drilling rig or a fire-cautious property. Dust control, compaction and seeding water on a construction or right-of-way job. Brine for road and lot de-icing on a contractor or municipal rig. Wash-down and equipment rinse water at a yard. A day tank on a plant floor between a bulk delivery and a process line. In every one of those the tank stands on its own feet, which is the whole point of the shape: nothing to fabricate, nothing to align, no saddle to buy. Two limits, stated plainly. This is a single-wall tank with no containment of any kind, so it is the wrong product wherever containment is required, and the sheet publishes no containment figure to lean on. And the 120 F / 48 C service limit is a real number on a dark deck in July, so shade the tank, fill it cool, or work it down before the afternoon. What ends a tank this size early is the mount rather than the liquid: a strap over the body instead of an anchor through the structure, rigid pipe bolted to a large outlet, or a part-full load driven fast.

Chowchilla or Marked Tree, an oversize load at 533 pounds

This tank is molded at Chowchilla, California and Marked Tree, Arkansas, and the sheet gives the class as OVS under NMFC 156600, shipping at 142 inches by 71 inches by 55 inches and 533 pounds. It moves as an oversize load rather than as ordinary freight, which means the route is part of the purchase: eleven feet ten inches long and five feet eleven inches wide does not reverse out of a bad approach, so confirm the gate, the turn, the overhead lines and where the truck can stop before the delivery is booked. The freight cost estimator prices the lane to your ZIP, and the listed price is before freight. Unload with a forklift, a telehandler or slings under the body, never a hook through the lid, and never by dragging the tank on its feet. Have the mount finished before the tank lands: anchor points through the structure, a mat or plywood on a ribbed deck, the straps in hand, and the pump position decided. Then water-test it in place before the first working load, fill to the lid with clean water, hold it, and read the feet, the deck, the outlet and the lid seal through the hold. On a tank with an outlet this size, the thing to buy in the same conversation is the hose and the fittings, because a 3 inch port with a smaller hose bolted to it is a 3 inch port you paid for and are not using. A strap that is checked once a season is a strap that holds; put it on the same calendar as the gutters.
