A 6502 gallon black heavy duty vertical tank for liquids heavier than water
The Norwesco 6502 gallon black heavy duty vertical storage tank, part number 47620B, is a polyethylene tank 102 inches in diameter and 196 inches tall, weighing 1700 lb empty. Heavy duty means a thicker wall rated for liquids up to 1.9 specific gravity, so it carries the dense fertilizers and chemicals that a standard tank cannot; 6502 gallons of water weighs 54227 lb, and the heaviest full load at 1.9 is 103031 lb. It comes with a 3 inch polypropylene female NPT bulkhead fitting with a 2 inch reducer as the outlet and a 16 inch threaded vented manway on top. The resin is FDA compliant per Norwesco, Norwesco lists the tank as NSF 61, the service limit is 120 F, and Norwesco backs the heavy duty tank with a 5 year warranty. Black keeps light out of the contents and protects light sensitive liquids.

Who buys the heavy duty 6502
This is the tank for a liquid fertilizer dealer, a chemical blender, a water treatment plant or a farm storing UAN solution, calcium chloride, brine or anything else that weighs more than water. If you are storing plain water or rainwater, the standard duty version of this size does the same job with a thinner wall and a 3 year warranty, and the heavy duty premium buys you nothing. The tank stands over sixteen feet tall on a circle eight and a half feet across, so it goes outdoors or in a building with real clearance, and the manway is reached from a ladder or a platform. Full of water it puts about 27 tons on the pad, and close to twice that with a liquid at 1.9. Our guide to sizing a concrete pad under an above-ground polyethylene tank covers what that slab has to do. For a reuse or process water train, the industrial water reuse tank topology guide shows where a tank this size sits in the stack.
What goes in it
Liquid fertilizers, brines, many acids and bases, and water. The 1.9 rating is about weight, not chemistry, so check the liquid in our chemical compatibility guide before it goes in, and keep the contents under 120 F; polyethylene softens as it warms and the rating assumes that ceiling. If the liquid is not on the list, tell us what it is and we will check it with Norwesco. For the volume, the tank sizing calculator and tank sizing guide turn a delivery size and a usage rate into the right gallons.
Openings and fittings
- Outlet. A 3 inch polypropylene female NPT bulkhead fitting with a 2 inch reducer, factory installed low in the wall. Run 3 inch for fast transfer into a nurse tank or a sprayer, or leave the reducer in and plumb 2 inch. Support the valve and the first length of pipe on their own; a full tank settles slightly and a rigid line can lever on the fitting.
- Manway. A 16 inch threaded vented manway on top. The vent lets air move as the level changes; a pump pulling against a plugged vent can collapse a tank wall.
- Inlet. No separate inlet is installed. Tell us before the order ships if you want a fill fitting at a set height.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the outlet position relative to the manway for piping layout.

Shipping and receiving
The tank ships LTL at freight class 300 from Norwesco's Albertville, Alabama plant, 102 by 102 by 196 inches and 1700 lb. It travels on its side on a flatbed, so you need a forklift or a loader with straps, and room to stand it up. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. At the tailgate, check the part number against 47620B on the bill of lading, look over the whole shell for transit damage before signing, and fill it with water the first time before it carries anything heavier.
