A 1000 gallon black 45 degree cone bottom tank that drains to the last gallon
The Norwesco 1000 gallon 45 degree cone bottom tank in black, part number 44640, is a polyethylene mixing and storage tank with a 72 by 72 inch footprint, 89 inches tall, weighing 240 lb empty. The 45 degree cone is the steep one: it sheds slurries, settled solids and thick liquids toward the outlet instead of leaving a ring behind, which is why 45 degree cones go under batch mixers and in chemical feed systems where the tank must empty completely. The tank is rated for liquids up to 1.5 specific gravity, which Norwesco states as a maximum of 12.52 lb per gallon; 1000 gallons of water weighs 8340 lb. The top opening is 16 inches. A cone bottom tank has no flat base and must sit in a stand: Norwesco's stand for this tank is part N-63934, sold separately, and the tank should not be ordered without it. Black blocks light, which protects light sensitive chemicals and holds algae back in water.

Mixing, batching and full drain-down
Buy a cone bottom tank when the tank has to empty itself: fertilizer batching, polymer and flocculant make-down, brine, wastewater treatment chemicals, or any liquid that settles. The 45 degree cone drains faster and cleaner than the 15 and 30 degree cones Norwesco also makes, at the cost of height, because the steeper cone adds to the overall height and raises the outlet when the tank sits in its stand. Our cone bottom buyer's guide covering the 15, 30 and 45 degree selection explains which angle suits which liquid, and the 1000 gallon cone bottom buyer's guide goes deep on this exact size. Before anything goes in, check the liquid in our chemical compatibility database; the entries for sodium hypochlorite, ferric chloride, aluminum sulfate, sulfuric acid and urea solution are the ones cone bottom buyers ask about most. Liquids heavier than 1.5 times water need a heavy duty tank, not this one. For the volume, use the tank sizing calculator and the tank sizing guide.
What to check before you buy
- The stand. N-63934, sold separately. A cone bottom tank cannot stand on its own; the stand cradles the cone at 45 degrees and lifts the outlet high enough to get a valve, a pump or a drum underneath. Order them together so they arrive together. Our cone bottom tank stand compatibility matrix lists which stand fits which tank.
- The outlet. No outlet fitting is listed with this tank. The cone apex is where the drain goes; tell us the size you want and we fit a bulkhead fitting before it ships, or we send it loose.
- The top opening. 16 inches, enough for a fill line, a mixer shaft or a level sensor and for a hand and a brush inside.
- Height in the stand. The tank is 89 inches tall on its own; the stand adds to that. Measure the ceiling and the space you need under the outlet before you order.
- The drawing. Norwesco's drawing for 44640, linked under Technical Drawing on this page, gives the cone geometry, the overall height and the opening position.
The same tank in white, and other shapes nearby
The same 45 degree cone in white, for reading the level through the wall: the 1000 gallon white 45 degree cone bottom tank, 43852; the swatches above the price switch between them. If you do not need full drain-down, the 500 gallon white applicator saddle tank, 40274 is the sprayer-mounted alternative.
Shipping and receiving
The tank ships LTL from Norwesco's St. Bonifacius, Minnesota plant, 89 by 72 by 72 inches and 240 lb; it travels on its side on a pallet. Two people or a forklift unload it. 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 44640 on the bill of lading, look over the cone apex, where transit knocks land, before signing, set the stand level on both diagonals, drop the tank in, fit the outlet valve, and fill it with water the first time.
