RomoTech 82123919 Horizontal Square Reservoir
The RomoTech 50 gallon tank is designed for outdoor, non-flammable liquids, with clear molded gallon/liter markings and UV-stabilized, rustproof poly construction. Best for buyers who need portable outdoor storage that won’t warp or fade in the sun. The oversized 5-1/2″ lid and built-in bulkhead with 3/4″ NPT outlet support easy refills and hose hookups for rapid dispensing. A potential limitation is that it is optimized for non-flammable liquids; avoid using it for flammable substances.
Rubbermaid Commercial Stock Tank
Rubbermaid’s 50-gallon stock tank emphasizes rugged, all-weather versatility. Best for buyers seeking a heavy-duty container for livestock watering, outdoor cleaning, or makeshift pools. It’s built for long life with a durable rigid-cell design and backed by a 10-year limited warranty. The tank is proudly made in the USA. A note: it’s a simple stock tank without built-in mixing features, so plan to use a separate mixer if you need active agitation.
Elkhart Plastics 50 Gallon Utility Tank
The Elkhart Plastics 50 Gallon Utility Tank is versatile for water and chemical transport in lawn care, recreation, or agriculture. It offers a large 6″ fill cap, 2″ NPS port, and 3/4″ NPT outlet for quick filling and dispensing. The translucent body with molded gallon/liter markings helps monitor liquid levels. UV inhibitors increase outdoor durability. Best for setups needing easy fill/dispense and clear level visibility; avoid relying on this tank for liquids exceeding 1.7 specific gravity.
MXBAOHENG 50 Gallon Pneumatic Paint Mixer Tank
This 50-gallon mixer tank pairs a stainless steel rod and blade with a pneumatic drive for reliable, durable mixing. Best for paint, coatings, and other viscous liquids where consistent dispersion is required. The unit features stepless speed regulation and two clamps for horizontal or vertical mounting, enabling flexible setup. A caution: ensure the clamp diameter or tank geometry fits your workspace, and follow safety guidelines for pneumatic equipment to avoid overloading or misalignment.
Class A Customs T-5000 50 Gallon Fresh Water Holding Tank
The Class A Customs 50 Gallon Tank is NSF-listed and suitable for fresh or gray water storage in RVs or concessions. It includes two 1.5″ female NPT fittings and two 0.5″ fittings, with measurements that allow orientation on multiple sides. Best for buyers needing compliant water storage with built-in fittings; consider the slightly variable manufacturing tolerances when planning precise mounting or plumbing layouts.
Buying Guide
What should I consider when choosing a 50 gallon mixing tank?
Purpose: Pick a tank based on intended liquid (water, non-flammable liquids, paint, or chemicals). For mixing tasks, prioritize tanks with accessible lids, bulkhead fittings, and clear level markings.
Material and durability
Look for UV stabilization, corrosion resistance, and a material suited to the stored liquid. Polyethylene tanks resist weathering and are lighter, while steel components may offer higher rigidity for certain rig setups.
Fittings and access
Assess fill caps, outlets, and NPT ports. Ensure you have compatible hoses and fittings for rapid dispensing and integration with pumps or sprayers.
Portability and installation
Consider tank shape (square, rectangular, round) and whether it fits your truck, trailer, or workspace. A flat bottom or versatile orientation helps with installation in limited spaces.
Safety and compliance
For potable water or NSF-listed uses, ensure materials meet safety standards. For chemical or coating applications, verify compatibility and non-reactivity with stored liquids.
Maintenance and longevity
Evaluate ease of cleaning and the availability of replacement parts such as lids and bulkheads. UV inhibitors extend life for outdoor deployments, while warranties indicate durability expectations.
