A 4,500 gallon heavy duty XLPE tank that stops at 91 inches
Snyder part number 7000400N48 is a 4,500 gallon heavy duty vertical storage tank moulded in black crosslinked polyethylene (XLPE), 143 inches in diameter and 91 inches tall, 1,100 lb empty. It is the widest and lowest shape in this capacity: just under twelve feet across and a little over seven and a half feet tall, so it goes into rooms with a joist for a ceiling. The wall is rated for liquids up to 1.9 specific gravity, Snyder's heavy duty rating, built for the dense acids, caustics and concentrated solutions an ordinary tank is not. 4,500 gallons of water alone weighs 4,500 x 8.34 = 37,530 lb, and a liquid at the full rating weighs 1.9 times that. The top carries an 18 inch threaded vented manway. Snyder puts the service limit at 140 F (60 C), and backs it with a 3 year warranty. Black keeps light off the contents.

The lowest manway in the family, and twelve feet of slab
At 91 inches the manway is reachable from a stepladder and worth a small fixed platform anyway. The cost is floor. A 143 inch circle will not pass a doorway and will not tuck into a corner, so walk the route from the dock to the pad with a tape before the order is cut. Under it, a rotationally moulded floor bears on the whole circle, and with a dense liquid the load is well over the 37,530 lb of plain water, so pour the pad to our concrete pad sizing guide, level and in full contact. Band it to structure or slab anchors while it is empty. Run 4,500 gallons against your draw in the tank sizing calculator and take the freeboard from the tank sizing guide.
What the heavy duty wall is for
Dense treatment and process chemicals, concentrated fertilizer solutions and the heavier acids and caustics that crosslinked polyethylene handles. Our XLPE versus HDPE guide explains when crosslinking matters for chemistry duty, and every liquid gets checked in the chemical compatibility guide before it goes in. If containment rules apply, the double wall freeboard sizing guide works out the usable volume a contained vessel really returns. A fire reserve is its own specification in a water rated vessel; the fire water reservoir design guide sets out why.
Openings and fittings
- Manway. An 18 inch threaded vented manway on top of a 91 inch shell. Land the fill on a permanent connection, run a dip tube to the floor so the stream does not foam the headspace, and keep the lid threaded shut between deliveries.
- Outlet. Tell us the liquid, the flow and the pump at order and we confirm the outlet this tank is supplied with before anything is drilled. With only 91 inches of liquid above the floor the suction head is small: mount the transfer pump below the outlet where gravity keeps it primed, fit a low level float, and carry the first valve on its own support with a flexible connector to the shell.
- Vent. Sized to the delivery pump and piped outdoors on anything that fumes.
- Drawing. Snyder's drawing for this tank is linked under Technical Drawing on this page.
Same shell, other ratings
Four ratings come out of this 143 x 91 inch mould. For a liquid near water weight the 1.35 SG walls are the honest answer: the 4,500 gallon 1.35 SG black tank and its twin the 4,500 gallon 1.35 SG black tank, part 7000400N33, or in natural colour the 4,500 gallon 1.35 SG tank. Nearby shapes: the 4,400 gallon XLPE tank is on another mould, and the 4,600 gallon XLPE tank is on a third.
Shipping and receiving
The tank ships LTL at freight class 300 from Snyder's plant in Chowchilla, CA, 143 x 143 x 91 inches and 1,100 lb on the truck. Tell us the site access, and have forks long enough to reach across the base or a crane ready on delivery day, with straps under the body and nothing rigged to the lid. Check the part number against 7000400N48 on the bill of lading. Set it on the cured pad in one move, fill it with water, hold it, and walk the full circumference twice.
