Bellows mechanical seals consist of rubber bellows and metal bellows variants. Removing dynamic O‑rings, they avoid O‑ring‑related failures and deliver reliable axial compensation. Rubber bellows seals serve general‑purpose water and chemical pumps at moderate temperatures, while welded metal bellows seals handle high‑temperature, aggressive‑media conditions for process pumps. Manufactured to EN 12756 (DIN 24960) standards with multiple face material combinations, ForMaxFluid bellows mechanical seals work as OEM replacement seals for centrifugal pumps across chemical, water‑treatment, petrochemical and marine industries.
Pusher mechanical seals, also known as spring‑loaded O‑ring mechanical seals, utilise dynamic sliding O‑rings as secondary sealing elements. Spring assemblies axially push the seal face assembly to compensate for face wear and shaft movement. Available in single‑spring and multi‑spring configurations, they follow EN 12756 (former DIN 24960) standards with broad material options. Single‑spring versions resist particle clogging for general‑purpose water pumps, while multi‑spring types deliver uniform face loading for high‑speed and larger‑size centrifugal process pumps. ForMaxFluid pusher seals serve as reliable OEM‑replacement sealing solutions across water‑treatment, chemical and light‑petrochemical industries.
Cartridge mechanical seals are fully pre‑assembled, self‑contained sealing units complete with sleeve, gland plate and all internal components. Eliminating on‑site spring‑compression adjustment and assembly errors, they enable fast pump installation and minimize downtime. Available in single cartridge and dual cartridge configurations: single‑cartridge seals serve general‑duty non‑hazardous process pumps, while dual‑cartridge seals adopt dual face sets for toxic, flammable or environmentally‑critical media with barrier‑fluid support. Manufactured to EN 12756 standards with diverse material combinations, ForMaxFluid cartridge mechanical seals are direct OEM replacement options for chemical, petrochemical, water‑treatment and pharmaceutical centrifugal pumps.
