The Norwesco 200 Gallon Plastic Pest Control Operator Tank in white is built for the working PCO rig: a 200-gallon polyethylene tank rated to a 1.5 specific gravity, which gives spray operators real headroom over a plain water tank. Whether you run it on a skid, a trailer, or a truck bed, the questions are always the same - does it hold the load, what does freight cost, and what catches people out. Here are the answers from this tank's actual data.
Does it work for your spray setup
At 200 gallons, a full tank of clean water carries about 1,668 lb of liquid weight. Because Norwesco rates this shell to a 1.5 specific gravity, the polyethylene is engineered to carry up to roughly 2,502 lb of contents - that is the rated ceiling for heavier-than-water mixes. That gives you 834 lb of headroom over plain water, meaning a working solution as heavy as about 12.5 lb per gallon is still within the rating. For a pest control operator running concentrated chemical loads, that 1.5 rating is the spec that matters: it is the difference between a tank sized for water and one sized to carry a denser solution without overstressing the wall. Mount it on a frame or skid rated for that loaded weight, and check the technical drawing on this page for the outlet and fitting layout before you plumb your pump and spray system.
Sizing the tank and the support under it
Use those numbers when you spec the trailer, skid, or pad. The 1,668 lb water figure is your baseline; the 2,502 lb rated-contents figure is what your frame and tie-downs need to handle at the SG ceiling. If you are still deciding between sizes, the Tank Sizing Calculator and Tank Sizing Guide walk through the capacity-versus-weight tradeoffs so you do not under-build the support structure. For mounted or stationary installs, the guide on concrete pad sizing for above-ground polyethylene tanks covers the load-spreading framework.
The mistake to avoid
The common error with a PCO tank is treating the 1.5 specific-gravity rating as a license to fill it with any chemical. The SG number tells you the tank can carry the weight of a denser solution - it does not certify chemical compatibility for every concentrate you might run. Match your pump and plumbing thread to the fitting shown on the drawing, confirm the gasket elastomer against your specific spray mix and polyethylene resin before extended service, and re-torque fittings after the first load. And never exceed the 2,502 lb rated-contents weight regardless of how much volume is left in the tank: filling a 200-gallon shell with a heavy concentrate to the brim can put you over the rated ceiling well before the tank is physically full.
This Norwesco 200 gallon tank ships LTL freight, quoted live to your ZIP from the nearest of Norwesco's 11 plants - Burnet TX, Fairfield TX, Griffin GA, Hanford CA, Lancaster OH, Owego NY, Shawnee OK, Sheldon IA, St. Bonifacius MN, Tooele UT, or Washougal WA. Because your tank almost always ships from a regional point rather than a single distant origin, LTL freight on this Norwesco PCO tank usually lands cheaper than a single-source competitor.
