Wellmate pressure tank in fiberglass

The construction of a Wellmate fiberglass hydropneumatic tank’s greatest advantage is its resistance to corrosion. It is manufactured in one piece, seamless inner body molded from premium high density polyethylene.

Heavy-duty air blow molded inner membrane is fully replaceable and constructed of heavy gauge engineered polymer bottom entry/plug assembly is custom routed from high impact PVC.

Advantages of the Wellmate pressure tank in fiberglass

  • Molded polymeric base with corrosion and impact resistance test.
  • The outer body is a continuous filament fiberglass composite sealed with high quality epoxy resin.
  • Replaceable air membrane.
  • NSF Approval: The entire range of WellMate residential tanks are NSF/ANSI-61 certified for human use.
  • Light weight – minimizes the cost of moving and loading maneuvers, without the need for heavy equipment.

The WM-Series offers features and benefits that steel tanks simply cannot match. From their corrosion resistant composite construction, light weight, easy maintenance and less costly installation, WM-Series pressure tanks are the preferred choice of professionals.

Features and Benefits

  • Replaceable inner tube ensures ease of field service.
  • Extended labor warranty option is available to owners.
  • It does not rust in corrosive environments, particularly important in coastal regions.
  • Faster and less expensive to install, they usually require only one person and fewer man-hours.
  • Wider pressure differential adjustment provides greater flexibility.

Applications

Residential: residential houses and subdivisions.

Light commercial: in wet warehouses, high corrosion production lines and beach hotels.

Pressure increase: From closed hastening systems.
