Flexaseal Mechanical Seals

PLUSSMART Technology is an authorised distributor for the catalog of engineered sealing products from Flexaseal, designed and manufactured in USA. We bring Flexaseal into the same reliability conversation we already have with you around vibration and condition-based monitoring. When the application and the data point to a sealing issue, we specify quality Flexaseal seals and seal support systems. When the data shows the pump is being driven into upset conditions — dry run, dead-head, and similar — we can help solve with ReliaPump and the wider PlusSmart toolkit, and still fit the right Flexaseal seal where the duty needs one. Better sealing options. Clearer decisions from the data you already trust.

Flexaseal slurry mechanical seal

Sealing Products

Flexaseal designs and manufactures mechanical seals and engineered seal support systems for demanding rotating equipment — and for everyday pump duties where reliability still matters. Through PlusSmart you can access:

  • Standard and engineered mechanical seals

  • OEM replacement seals

  • Seal support systems

  • Fully split cartridge seals (including dual)

  • Repair support via Flexaseal Australia

Every application is reviewed and quoted to the duty — so the seal matches how the machine actually runs, not only the nameplate.

Technology Spotlight

Beyond a full catalog of quality seals, Flexaseal brings distinctive technologies for regular and severe service.

Triple-Ply Metal Bellows

Currently the only seal manufacturer offering triple-ply metal bellows — exceptional axial and radial strength for very high temperatures and extreme pressure (triple-ply rated above 100,000 kPa).

Typical fits: geothermal and coal-fired boiler feed.

Flexaseal FlexICE diamond-coated slurry seal

FlexICE™ Cold-Bonded Diamond Coating

Diamond-like carbon applied by low-temperature PA-CVD (~160°C), bondable to almost any substrate including tungsten carbide. Tough faces for severe pressure differentials and extended low-lubrication or dry-run capability. Typical fits: boiler feed and high-pressure slurry dewatering.

Flexaseal fully split cartridge seal

Fully Split Cartridge Seals

Flexaseal originated the fully split cartridge mechanical seal and leads in ease of installation and reliability — including fully split dual designs. Typical fits: large-shaft water or turbine pumps, and minerals duties such as tailings.
