WellMate Advantages

  • Corrosion-proof composite construction - From the high density polyethylene inner liner to the fiberglass-wound and epoxy resin-sealed outer shell, WM-Series tanks contain no steel. So they can’t rust.
  • Little or no maintenance - Because they contain no steel, there is no paint to scratch or touch up.
  • Longer life, greater flexibility -Our unique air cell offers longer life than the bladders or diaphragms in steel tanks. WM-Series tanks can be installed with a wider range of pressure settings, so you can select the system pressure you want. What’s more, the bottom inlet/outlet assembly is pre-installed and comes with system connections to save time and money.
  • Light weight - WellMate tanks are quicker, easier and less costly to install than steel tanks.
  • NSF and/or FDA listed materials - The complete assembly meets stringent US requirements for water components. WellMate tanks are environmentally safe, 100% lead-free. They will not introduce undesirable chemicals or elements into your customers’ water.
  • Replaceable air cell - Easy to service in the field.
  • Factory-backed warranty - WellMate backs its pressure tanks with a complete warranty, giving your customers the confidence and peace of mind that can turn them into buyers.
