Norwesco 70 Gallon Plastic Applicator Saddle Tank in White

Seventy gallons between a sixty-five and an eighty-five

This record sits in the middle of three parts and the middle is where it earns its place. Below it the N-44099 holds 65 gallons in a 43 by 23 by 26 inch body, and above it the N-45105 holds 85 gallons in a 52 by 26 by 26 inch body at 29 lb. Look at the dimensions rather than the gallons and the picture changes: this tank and the 65 gallon record are within an inch of each other in every direction, and the 85 gallon record is wider as well as longer. So the real step in this range is not from 65 to 70, it is from 70 to 85, where the width grows from 23 inches to 26. If the space you are filling is 23 inches across, this record takes you as far up the capacity ladder as you can go without redesigning the space, and that is the argument for it. There is one oddity in the family worth stating plainly rather than smoothing over: the sheet gives the 65 gallon N-44099 a weight of 119 lb against this record's 25 lb, and it names that part a chemical injection tank rather than a saddle tank. Those are two different products doing two different jobs, and we print both figures exactly as the sheet carries them without explaining a difference the record does not explain. Do not read the 65 gallon row as a cheaper version of this one. On the support side the sheet publishes nothing at all, so nothing is claimed here: no strap, band, cradle, frame or fixing specification appears on the record, and how this shell is carried and held is your design and your responsibility. What the record does give you is the load to design against. Empty it is 25 lb, which is a one-person item. Full, the published maximum contents figure is 876 lb where 70 gallons of water is 584 lb, and all of that is carried by whatever the moulded floor lies against, in continuous contact across the whole footprint rather than on rails or packers. Work the volume out against your actual draw with the tank sizing calculator, and take the freeboard discipline from the tank sizing guide.

Sixty-five, seventy, eighty-five

Only the first and third rows are the same kind of product; the middle row is a chemical injection tank by name and carries a weight figure far out of line with the other two, which we print without adjustment. Between this record and the 85 gallon N-45105 the comparison is clean: 44 inches of length and 23 of width here, against 52 and 26 there, for a step up from 70 gallons at 25 lb to 85 gallons at 29 lb. Height is the same 26 inches on both, so if you have headroom and you are short of length, the bigger shell will not help; if you have length and width to spare, it is the straightforward step up. The diameter field on this record reads 23 inches, matching its width, and that is as much as the sheet says about the cross-section. Read the table by the dimension that is actually scarce where the tank has to go, and let the gallons fall out of that. Buying by capacity and then discovering the width is the constraint is the most common way this size of tank ends up going back. For the wider context of where these shells sit in fertilizer work, our article on applicator and leg tanks covers the range, and the piece on loaf-style portable utility tanks in farm fleet use covers the portable shells alongside them.

The lid is the vent; the outlet is three quarters of an inch

• On this record the lid and the vent are the same component: the lid field reads 5 inch threaded vented lid, the lid size field reads 5 inches, and there is no manway and no second opening anywhere on the sheet.
• That makes the lid the single most important part on the tank. A plain lid fitted in place of the vented one turns every draw-down into a vacuum, and the two are indistinguishable at arm's length, so verify what is actually fitted before the first fill.
• Never seal or tape the vent to stop slop in transport. Carry less liquid instead; a blocked vent will pull a 70 gallon shell in and there is no repairing that.
• A 5 inch opening takes a fill line, a light and a hand. Rinsing is a wand-and-flush job, which matters more on a tank that may see more than one liquid over a season.
• The outlet field reads 3/4 inch PP female NPT bulkhead fitting, matched to the volume, and it is the honest limit on transfer rate. Size the pump and the hose to the port, not the reverse.
• Fit a short union immediately downstream of the bulkhead so every later fitting change stays away from the bulkhead thread itself.
• Carry any valve or filter on the structure under the tank rather than on the shell. At this size the fitting hardware can weigh more than the wall should be holding.
• Keep a spare lid gasket and a spare bulkhead gasket wherever the tank works. They cost almost nothing and they are the parts that end a working day.
• There is no inlet field, so filling is through that same lid. Fit a fixed fill point if the tank is topped up in place rather than balancing a running hose on the rim.

The published limits are the service limit, 120 F / 48 C, and the warranty field, which reads 3 Year Warranty. Ask us and we will get Norwesco's current written terms rather than stretching three words into a promise here. On density the sheet gives 1.5, quoted as a maximum of 12.52 lb per gallon, with a maximum contents figure of 876 lb against 584 lb of water, and that is the full density statement on this page.

Rinse water, spot work and small batches

Seventy gallons is a working quantity rather than a storage quantity, and the jobs match that. Rinse and wash water kept where the equipment is cleaned; a small batch of a mixed liquid made up for one task and used the same day; spot work on a limited area where hauling a larger tank would be absurd; a supply feeding a small pump or metering setup; clean water carried alongside a job so nobody drives back for it; and a second tank running a different liquid beside a larger one. At 25 lb empty one person handles it, and at 26 inches tall the lid is reachable from beside it wherever it ends up. The limitation to keep in front of you is the same one that comes with every convenient size: it is easy to move empty and it is 584 lb of water when full, with a published maximum contents figure of 876 lb, so the structure holding it has to be designed for the full number rather than the number you feel when you lift it off the truck. If the tank is going to run more than one liquid across a season, plan the rinse routine before the first fill rather than after the first changeover, because a 5 inch opening rewards a flushing habit and punishes a reaching one. Check every liquid you intend to put in it against polyethylene in our chemical compatibility reference before ordering, and call us if the reference does not answer it.

Which liquids, at what concentration, with which fitting

Each entry pairs a rated liquid with its concentration limit and the fitting and gasket to order alongside the tank. The full rating sits on the linked page and in the chemical compatibility database before ordering.

• acetic acid (60%, PP/PVC fittings, EPDM gaskets)
• aluminum sulfate (50%, PVC/EPDM)
• calcium chloride (40%, PVC/EPDM)
• DEF (32.5%, 316SS/EPDM)
• ferrous sulfate (20%, PVC/EPDM)
• magnesium chloride (30%, PVC/EPDM)
• sodium carbonate (30%, PVC/EPDM)
• urea solution (50%, PP/PVC/EPDM), and ozonated water (up to 10 PPM, PVC/EPDM).Always confirm the exact chemical, concentration, temperature, and fitting
• sodium hypochlorite sodium thiosulfate, sulfuric acid, and zinc orthophosphate all call for a higher 1.5 SG tank - do not run them in this 1.5 SG applicator.

Two plants, and the shortest origin list in this range

This record names two plants and no more: Lancaster, Ohio, and Sheldon, Iowa. The ship-from states match them exactly at Iowa and Ohio. That is the narrowest origin list of any tank on this sheet, and it is the single most useful thing on the shipping block, because it tells you the lane is measured from the midwest wherever you happen to be. A buyer in the west or the southeast should treat the freight figure as a real part of the decision rather than a rounding error, and should ask about timing as well as cost. The freight class field and the ship mode field both read LTL, the NMFC field is 156600-02, the shipping weight is 25 lb against the same 25 lb empty, and the crated dimensions repeat the tank at 44 by 23 by 26 inches. The freight cost estimator prices the lane to your ZIP, and the listed price is before freight. At 25 lb this comes off the truck in one hand and will therefore be handled without much ceremony, so look it over carefully rather than quickly: turn the lid on its thread by hand, check the bulkhead boss from below, and run a palm along the bottom for gouges where it has slid on a deck. Fill it with clean water where it is going to be used, leave it a few hours, and check underneath before it goes into service. Then do the one thing people skip on small tanks: write down what liquid it is dedicated to, on the tank, on the day it arrives, because a 70 gallon shell that has held two different things and been labelled for neither is a problem nobody can fix later. Keep one spare gasket for the outlet fitting on the shelf; it is the part that fails on a holiday.
