Advantage polyethylene pump tank stations pair a poly reservoir, up to 3,000 gallons, with a pump sized to the required flow, up to 2,700 GPM across the range. Poly construction is corrosion-resistant and lighter than an equivalent steel tank, which matters both for the fluid chemistry it can tolerate and for installation where floor loading or handling weight is a consideration.
These are the default choice whenever the circulating fluid, additives, or ambient environment would attack a steel tank over time - certain glycol chemistries, water treatment additives, or corrosive plant atmospheres are common reasons to specify poly over steel.
Tell us the reservoir volume and flow rate your loop requires and we'll match a station; if you're unsure whether poly or steel is the right call for your fluid chemistry, send us the fluid and additive details and we'll advise.
Polyethylene is the default for an Advantage station whenever fluid chemistry or ambient atmosphere would attack steel over time - certain glycol formulations, water treatment additives, and corrosive plant environments all favor poly. It's also the lighter option, which can matter for floor loading on an elevated mount or for handling during installation.
Poly does have a lower practical temperature ceiling than steel and isn't the right choice where a code or structural spec calls for a steel vessel - tell us the operating temperature and any code requirement along with your volume and flow so we can confirm poly is still the right material before quoting.
| Factor | Polyethylene | Mild Steel |
|---|---|---|
| Corrosion resistance | High - inert to most glycol/water chemistries | Lower - coating typically needed for aggressive fluids |
| Weight | Lighter | Heavier |
| Temperature tolerance | Lower practical ceiling | Higher |
| Structural rating | Standard | Higher - meets stricter structural or code requirements |
| Reservoir volume / flow range | Up to 3,000 gal / 2,700 GPM | Up to 3,000 gal / 2,700 GPM |
Both tank materials share the same sizing range - the decision is chemistry, temperature and structure, not capacity. Call and talk it through with an engineer: 1-805-484-2992.
