The Snyder Industries 1615 Gallon Super Nurse Tank with Center Sump is a horizontal transport tank built for moving liquid fertilizer, ag chemicals, and water between the supply point and the field. It holds 1,615 gallons, stands 61.25 inches tall on a 69 x 140 inch footprint, and is molded from white polyethylene with a 1.9 specific gravity rating. The center sump is the feature that sets this SKU apart from a flat-bottom horizontal: it pulls contents toward a single low point so the tank drains down nearly complete, leaves less heel behind when you switch chemistries, and gives your pump a clean suction point. Sized as a nurse tank, it rides on a trailer or skid, which is why the SG rating and full-load weight matter more here than on a stationary tank.
Will it work for your load?
Match the tank to the weight of what you are hauling, not just the gallons. Filled with water, this tank carries about 13,469 pounds of contents; at its maximum rated content weight it is built to carry up to 25,591 pounds. That spread is the whole point of the 1.9 SG rating, which is the top wall rating on this tank: it lets you run dense fertilizer blends and heavy chemistries without overloading the poly, and there is no denser-service tier to step up to. Before you commit, run your liquid's gallons and specific gravity through the Tank Sizing Calculator and confirm the loaded weight against your trailer and axle ratings. The Tank Sizing Guide walks through how SG, capacity, and transport weight tie together so you size the rig once and get it right. Because this is a heavy, oversize LTL item that ships from a single plant, it is worth pulling a freight estimate from the Freight Cost Estimator at the same time you settle on capacity.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating. The resin is recorded as HDLPE, but confirm HDLPE versus XLPE for your chemical before putting it into chemical service, since cross-linked and high-density linear polyethylene differ in resistance. On a tank like this the wall handles almost everything at the 1.9 SG rating, so the real failure point is usually the fitting and gasket, not the poly. Match them to your exact chemistry, and always verify against the OEM chemical-resistance chart, which is concentration- and temperature-specific. Common chemistries this tank can carry at the SG rating include:
- Acetic acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ethylene glycol (100%) - PVC fittings, EPDM gaskets
- Ferric chloride (50%) - PVC fittings, EPDM gaskets
- Hydrochloric acid (37%) - PVC fittings, Viton gaskets
- Hydrofluoric acid (48%) - PP/PVC fittings, Viton gaskets
- Hydrogen peroxide (50%) - PVC fittings, Viton gaskets
- Phosphoric acid (85%) - PVC fittings, Viton gaskets
- Potassium hydroxide (saturated) - PVC fittings, EPDM gaskets
- Sodium hypochlorite (under 16.5%) - PVC fittings, Viton gaskets
- Sulfuric acid (98%) - CPVC fittings, Viton gaskets
- Urea solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated water (up to 10 PPM) - PVC fittings, EPDM gaskets
The pairings are not interchangeable: use Viton (not EPDM) gaskets for hydrochloric, sulfuric, phosphoric, hydrogen peroxide, and sodium hypochlorite; Aflas with 316SS for peracetic acid; and 316SS fittings for DEF, which must run stainless rather than PVC to keep the fluid uncontaminated. The full list also covers ferric sulfate, ferrous sulfate, hydrofluosilicic acid, magnesium chloride, peracetic acid, polyaluminum chloride, potassium carbonate, propylene glycol, sodium bisulfate, sodium bisulfite, sodium carbonate, sodium thiosulfate, and zinc orthophosphate. See our full chemical compatibility resource and the individual chemical pages for the concentration- and temperature-specific OEM data before you order fittings.
The mistake to avoid
The most expensive error on a nurse tank is treating the gallon number as the limit. The wall is rated to 1.9 SG, but your trailer, hitch, and axles have their own ceilings, and a full load of dense fertilizer pushes well past the 13,469-pound water figure. Confirm your loaded weight before you spec the rig, and on the regulatory side, check whether your transport falls under the DOT and 49 CFR ag-exemption rules covered in our guides on portable utility tank DOT classification and applicator and leg tanks for fertilizer. If you are blending on the fly, our note on fertilizer-blend tank stratification explains why dense layers settle and how to catch it. For dedicated double-wall containment, see Snyder Captor double-wall tanks for SPCC compliance.
