Snyder Industries 225 Gallon Plastic Chemical Injection Tank

Sited by the pump, not by the wall

An injection tank holds the supply a metering pump draws on continuously, so three things decide where it goes: the lift the suction has to make, the reach an operator needs to the lid, and the floor that carries the arrangement. At 72 inches tall the opening is at or above head height for most people, so plan a fill hose rather than a jug and a step for anyone who wants to look inside. In exchange the liquid column sits high enough that a pump on the same slab draws across and down rather than pulling up, which is worth more to a metering loop than any other feature here. Give the base flat, continuous, level bearing across the whole footprint: a slab, a curbed pad or a structural deck, never two rails and never shimmed at one corner. Level matters more on a wide low tank than a tall one, because the last gallons in the bottom are the ones a tilt hides from the suction.

Before the footprint is committed, check that 225 gallons is the right tier for your dosing rate and delivery interval in the tank sizing calculator, and take the freeboard a warming or gassing product wants from the tank sizing guide; a dosing tank filled to the lid has nowhere to expand and nothing left for the operator to read. If the loop needs a level reading, our level gauge selection guide for chemical service compares the technologies.

What goes in it

Check the chemical in our chemical compatibility guide before the first fill. Injection tank buyers ask most about sodium hypochlorite, sodium bisulfite, phosphoric acid, polyaluminum chloride and zinc orthophosphate. The 1.9 rating covers liquids up to 1.9 times the weight of water. Once a chemical is in it, our notes on tank labeling and signage compliance and drawing a representative chemical sample cover the two jobs an inspector asks about.

Openings and what to confirm

1. Lid. A 6 inch threaded vented lid on top: enough for a fill hose and a level sensor, not for a hand. Confirm the vent is routed where fumes do no harm.
2. Outlet. Not stated on this listing. Snyder's drawing shows the fitting positions; tell us the pump suction size and we will confirm what is installed and what you add.
3. The envelope. 89 by 54 by 72 inches as listed. Ask us what that includes before the pad is poured.

Shipping and receiving

The tank ships LTL from Snyder's Marked Tree, Arkansas plant, 89 by 54 by 72 inches at 266 lb. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. Have a pallet jack or forklift at the tailgate. Check the part number against 1003900CITS45 on the bill of lading, look over the lid and the base for transit damage, and fill with water the first time before it carries chemical.
