AESSEAL® is a UK-based specialist in the design and manufacture of mechanical seals, seal support systems, bearing protectors and gland packing, founded in 1979 and headquartered at its Global Technology Centre in Rotherham, England. Its sealing solutions are used on pumps and rotating equipment across oil and gas, chemical, mining, water, food, pharmaceutical and other process industries. AESSEAL operates from more than 100 locations in over 100 countries, with 9 manufacturing sites and around 50 repair centres, and keeps one of the industry's most comprehensive standard inventories of seals and sealing products.
Single and dual cartridge seals (pusher and metal bellows) qualification-tested to API 682 for API 610 pumps in oil, gas and petrochemical service, including compact thin cross-section (TXS) versions for older pump designs.
Non-contacting labyrinth bearing isolators rated IP66 as standard and up to IP69K, available in axial-movement, air-purge, radially split and top-entry versions for pumps, motors, gearboxes, pillow blocks and steam turbines.
Magnetically energized contacting-face bearing seals that block contamination and prevent lubricant loss, well suited to pure oil mist applications.
Double monolithic stationary seals with flow or convection barrier fluid circulation for hazardous, toxic or difficult process duties.
Heavy-duty double stationary cartridge seals built for mining tailings and abrasive slurry pumps, with hydraulically balanced faces and abrasion-resistant materials such as solid tungsten carbide.
Modular, CE-certified seal support systems, including self-replenishing water barrier systems that greatly reduce plant water use.
Pre-assembled, pressure-tested single, double, bellows, split and mixer seals for centrifugal pumps and rotating equipment.
An extensive range of non-cartridge mechanical seals, with around 10,000 product lines available from stock.
Seals that can be installed or replaced without dismantling the pump or equipment, minimising downtime.
Seals such as the CDM and SCMS designed to handle radial and axial shaft movement, running wet, dry or with a gas barrier.
Gas-lubricated sealing solutions for compressors, API pumps, process pumps and reactors, including hydrostatic/hydrodynamic compressor seals.
Barrier and buffer fluid systems, forced circulation systems (API Plan 54), gas panels, leakage detection (API Plans 65 and 75), particle separators and cooling units, built to ASME VIII and PED standards.
Contacting and non-contacting bearing isolators for pumps, electric motors, gearboxes, plummer/pillow blocks and steam turbines, with ATEX-certified options.
Compression packing for pumps and valves, including high-performance styles such as 789TP ProStar.
A broadly applicable, high thermal-resistance elastomer for mechanical seal O-rings.
Wireless monitoring devices such as System Sentry, a wireless sight glass for API Plan 53B systems.
Repair services for AESSEAL and competitor seals, including dry gas compressor seals.
The Standard Plus range adapts standard designs to replace competitor seals and fit specific pumps or processes.
On-site and online seal technology training and support for reliability and condition-based monitoring.
