The Norwesco 50 Gallon Pest Control Operator Tank is a compact white polyethylene tank built for the spray rig, the service truck, and the PCO route where you need a portable supply tank with a 1.5 specific-gravity load rating. At 50 gallons in a polyethylene shell, it carries the load a pest-control operator actually mixes, and the white resin lets a tech eyeball the fluid level at a glance. This is a Norwesco 50 gallon tank purpose-built as a PCO tank, not a repurposed water cistern.
Will this tank handle my load?
Norwesco rates this shell to a 1.5 specific gravity, which is the number that matters when you fill it with something heavier than water. Plain water fills it at about 417 pounds; at the tank's full rated specific gravity, the contents can reach roughly 626 pounds. Use those two weight numbers to size your mounting platform, your tie-downs, and the axle rating on the trailer or truck bed carrying it. The 1.5 SG rating gives you real headroom over plain water service for the denser concentrate mixes a pest-control operator runs, but always confirm your specific blend against the chemical's own data before filling. For dialing in the right footprint against your bed or skid, the Tank Sizing Calculator and the Tank Sizing Guide walk through capacity, weight, and clearance so you are not guessing. If your concentrate runs heavier than 1.5 SG, size up to a higher specific-gravity-rated tank rather than overloading this shell.
Specs and what to check before you mount it
Review the technical drawing on this page for the molded-in dimensions, fitting locations, and outlet placement so your plumbing and pump pickup line up before the tank ships. Fitting and outlet sizes are shown on that drawing, so confirm them against your pump and hose before you order. Then run a simple two-part compatibility gate: first, verify your mixed product's specific gravity sits at or under the 1.5 rating; second, verify your fittings and gaskets are rated for the concentrate you are pumping. The most common mistake on a PCO tank is filling a 1.5-rated shell with a concentrate heavier than 1.5 SG, or pairing it with fittings and seals the chemistry will attack faster than the tank wall itself. The polyethylene body is the easy part; the fittings and gaskets are where service life is usually lost. If you are mounting the filled tank on a fixed pad rather than a truck bed, our guide on concrete pad sizing for above-ground polyethylene tanks covers the load math.
