65 Gallon 40 Degree Cone Bottom Inductor Tank: Complete Buyer's Guide
Sixty-five gallons of mixing capacity stacked into the same 27-inch footprint as its smaller sibling — the extra volume goes up, not out. The 40-degree Norwesco cone drives every concentrate toward the tip, so a busy chemical line can blend a bigger batch without surrendering bench space.
Specifications at a Glance
Every figure below is pulled straight from the live product record for this exact tank — the same data on the product page, so what you read here and what you buy never disagree.
Standards & Materials
- ASTM D1998 — Standard Specification for Polyethylene Upright Storage Tanks. Governs wall-thickness and hydrostatic design for vertical rotomolded poly tanks of this class.
- FDA 21 CFR 177.1520 — Olefin polymers. The food-contact regulation the FDA-grade resin in this tank is compounded to meet.
- Specific gravity rating 1.5 — the tank is engineered for liquids up to 1.5× the density of water (water is about 8.34 lb/gal). Confirm your fluid’s SG before storage.
Product Overview
Step up from a 40-gallon inductor and the question is rarely "how much floor will it take?" It is "how much taller does the column get?" The 65 Gallon 40 Degree Cone Bottom Inductor Tank answers that by keeping the 27-inch diameter and adding height — 43 inches overall — so a mix station that already fits can hold half again as much blend without redesigning the bench.
The 40-degree cone is the working heart of the tank. Dry chemical, concentrate, or wettable powder charged through the top slides down the slope to a single low outlet, where it can be recirculated or eductor-drawn into a larger tank with nothing left stranded on a flat floor. That clean drain is what separates an inductor from a storage drum, and at 65 gallons it lets an operator batch a meaningful volume between charges.
Weight is where the extra capacity makes itself felt. The shell is still light at 35 pounds empty, but a full 65-gallon charge at the 1.5 specific-gravity rating loads roughly 848 pounds onto the stand — over 300 pounds more than the 40-gallon version. The stand must be sized for that number, because the cone transfers all of it through the tip. Norwesco molds the body as one seamless piece of translucent white polyethylene, so the operator reads the level through the wall, and the 16-inch lid opens wide for charging, mounting an agitator, or cleaning the cone.
Like every cone-bottom inductor, this is dedicated chemical-handling gear. It is engineered to induct and blend agricultural and industrial solutions within its density band, not to hold drinking water, and it carries Norwesco's 3-year warranty against manufacturing defects.

Installation and Setup Guide
Installing a 65-gallon inductor is mostly an exercise in supporting weight correctly. The tank is light; the full charge is not, and all of it lands on the cone.
Stand and Support
Use a cone-bottom stand rated for the full loaded weight — roughly 848 pounds at 1.5 specific gravity. That is a notable jump over a 40-gallon unit, so do not reuse a smaller stand on the assumption that "a cone is a cone." Level the stand on solid concrete, verify every leg shares the load, and let the cone hang true. The tip is a drain, never a foot; bear weight on the apex and you stress the one geometry least able to take it.
Plumbing the Cone and Eductor
Connect the cone outlet to your recirculation pump or eductor with a short, full-bore run so the steeper liquid column above the tip pushes the last of the batch out cleanly. A full-port valve at the tip keeps partly dissolved powder from bridging the opening. Take the first connection in chemical-rated flex hose — the taller 43-inch column means more thermal movement at the base, and rigid pipe will eventually fatigue the fitting.
Ventilation
A larger charge means more vapor and dust during induction, so ventilation matters more here than on a small benchtop unit. Keep the lid seated while agitating to contain splash from the deeper liquid column, fit a vent matched to the chemistry rather than a plain screen, and keep emergency eyewash within arm's reach of the charging point.
Maintenance and Long-Term Care
Maintenance on a 65-gallon inductor follows the rhythm of the work: clean the cone, check the tip, watch the wall, and keep the chemistries separated.
Between-Batch Inspection
- Cone evacuation: Confirm each batch drains to a dry tip. With the taller column, a slow or partial drain usually means settled solids or a fouled tip valve rather than a cone-angle problem.
- Tip valve wear: The bigger the batch, the more abrasive slurry passes the seat. Cycle the valve and replace it at the first sign of dribbling shutoff.
- Wall and weld: The seamless mold has no weld to fail, but scan the translucent wall for crazing or a swollen patch — the fingerprint of an over-aggressive concentrate.
- Stand load: Re-check that the stand still carries 848 pounds square and level; a settling floor under one leg tips the cone and traps product on the high side.
Decontamination Between Chemistries
Flush and decontaminate the full tank, cone, and outlet line to the chemical maker's procedure before changing products. A larger vessel holds more residual concentrate in its corners, so a token rinse is not enough — cross-contamination at this volume can spoil a sizable downstream batch. This equipment is never returned to potable service.
Long-Term Care
Keep the unit out of direct sun and the resin will age slowly; the consumables — tip valve, agitator seal, lid gasket — are what you replace over the years. Stock spares so a worn part is a five-minute swap, not a lost shift.
Alternatives and Comparisons
The 65 Gallon 40 Degree Cone Bottom Inductor Tank competes within the cone-bottom mixing family, and the decision is about batch size versus bench height.
Sizing the batch: Sixty-five gallons is the sweet spot for a line that has outgrown a 40-gallon mixer but is not ready for the floor space and weight of a 80-gallon or larger unit. Because the diameter holds steady at 27 inches, the gain comes as a taller column — confirm you have the overhead clearance above the stand before you size up.
Cone angle: The 40-degree slope balances clean drainage against a reasonable overall height. If your chemistry settles fast or runs sticky, a steeper 45-degree cone clears it more completely at the cost of standing taller; if it stays in suspension easily, the 40-degree angle is plenty. Pick the angle for your slurry's behavior.

Frequently Asked Questions
How long will the 65 Gallon 40 Degree Cone Bottom Inductor Tank last?
With compatible chemistries, a correct stand, and shelter from direct sun, the seamless poly shell comfortably exceeds 15 years. On an inductor the limiting factor is almost always the duty cycle, not the plastic — abrasive slurries wear the tip valve and aggressive concentrates can eventually craze the wall. Thorough decontamination between products and a post-batch cone inspection are what carry the tank to the high end of its service life.
What chemicals can I store in this tank?
This is dedicated chemical-mixing equipment rated to 1.5 specific gravity, built to induct and blend agricultural and industrial concentrates within that density — liquid fertilizers, surfactants, wettable powders, and water-based cleaning chemistries. It is not for fuels, solvents, or flammables, and not for drinking water. Always confirm a new product against a polyethylene compatibility chart first; some oxidizers and hydrocarbons degrade poly even at moderate concentration.
Does this tank come with a warranty?
Yes — the shell carries Norwesco's 3-year warranty against material and workmanship defects when used within its ratings. It covers molding flaws such as pinholes and voids. It excludes chemical attack from an incompatible product, a cone damaged by tip-loading, and wear to valves and seals, which are expected to be replaced over a mixing tank's life. Keep your invoice and a photo of the tank correctly seated in its stand.
Can I install this tank underground?
No. The steep, thin-walled cone that makes this tank drain so cleanly is the opposite of what soil pressure demands — backfill would crush it inward, and burial voids the warranty outright. It is above-ground working equipment. For below-grade storage, use a purpose-built underground cistern engineered with ribbed, reinforced walls.
Buying Considerations
Three checks before you order the 65 Gallon 40 Degree Cone Bottom Inductor Tank. First, the stand — size it for the roughly 848-pound full charge, which is well above what a 40-gallon stand carries; the tank cannot stand alone. Second, the overhead — because the extra capacity is added as height (43 inches of tank on top of the stand), confirm you have clearance to charge the lid and mount any agitator. Third, compatibility — verify your concentrates are poly-safe and within the 1.5 specific-gravity limit, since this is a chemical mixer and never a water tank. At 35 pounds empty it ships UPS or FedEx ground in 5 to 7 business days.
