The Snyder Industries 9500 Gallon HDPE Vertical Chemical Storage Tank is a 1.9 specific-gravity vertical storage tank built for heavy bulk chemical service - the duty where contents weigh far more than water and a 1.0-rated tank would be the wrong call. It holds 9,500 gallons in a 120-inch by 120-inch footprint and stands 215 inches tall, molded by Snyder from polyethylene in white. Because it carries a 1.9 SG rating, this vertical tank is engineered for dense liquids up to a maximum rated contents weight of 150,537 lb - and that figure matters: at 1.9 SG a full 9,500-gallon charge of the densest compatible chemical comes in near 150,500 lb, so you can fill this tank essentially full even on a heavy chemistry, not derate it the way a lower-rated vessel would force you to.
Will it work for your install?
Plan the pad and the rigging around real numbers. The footprint is 120.0 x 120.0 inches and overall height is 215 inches, so confirm doorway clearance and overhead access before delivery. Full of water this HDPE storage tank weighs 79,230 lb; loaded to its 1.9 SG ceiling it reaches 150,537 lb, so the foundation must be engineered for the heavier figure when you store a dense chemical. The fitting package shown on the technical drawing on this page includes a flange, an 18" PE threaded/vented fitting, a manway with 15" access, and two 12" x 24" fittings (one flat). That 15"-diameter manway access is the spec to check for internal inspection and cleaning on a 215"-tall vessel - confirm a person and your cleaning gear fit through it. Use the technical drawing to verify outlet and manway locations against your piping and access plan, and run your volume through the Tank Sizing Calculator or the Tank Sizing Guide if you are still settling on capacity. On a vertical tank this size, level instrumentation is its own decision - see our guide on level gauge selection for chemical service.
Chemical compatibility
This tank is rated to 1.9 specific gravity. The resin designation in our data is not yet fully resolved, so confirm whether your unit is HDLPE or XLPE with us before committing it to chemical service - cross-link density changes the chemistry it can safely hold. Always check the OEM chemical-resistance chart, which is concentration- and temperature-specific, against your exact contents, and pair the tank with the correct fitting and gasket materials. Most chemicals below run on PVC fittings; the exceptions are the ones that cost you if missed: DEF and Peracetic Acid require 316SS fittings (not PVC), Sulfuric Acid 98% uniquely requires CPVC, Peracetic Acid uniquely requires an Aflas gasket, and a Viton gasket is mandatory on hydrochloric, sulfuric, phosphoric, hydrofluoric, hydrofluosilicic, hydrogen peroxide, and sodium hypochlorite service - EPDM will fail against those.

The mistake to avoid
The most expensive error on a tank this size is mismatching the SG rating to the contents. This is a 1.9 SG vessel - do not assume the next size up or a different family carries the same rating, and confirm the resin type before chemical service. Just as critical: get the fittings and gaskets right. Several chemicals here demand Viton over EPDM, Peracetic Acid demands an Aflas gasket, DEF and Peracetic Acid require 316SS hardware, and Sulfuric Acid at 98% specifically calls for CPVC rather than standard PVC - a wrong gasket or fitting is a leak waiting to happen. Before bulk service, label and placard the tank correctly - see our guide on label and signage compliance - and set an analysis cadence with our chemical sampling protocol. If you need secondary containment, compare approaches in our Snyder Captor Plus 110% containment vs UL-142 SPCC writeup.
