Seal Selector
58 seal types. One data sheet each.
Every mechanical seal we build — with size, pressure, speed, temperature, face materials and application. Filter by family, search a code, or let the selector point you to the right family in seconds.
Beyond the Seal
Rubber, springs & hard-face materials
Elastomer & Rubber Products
Complete range of industrial rubber for sealing duty — O-rings, gaskets, bellows, diaphragms, U-cups and buffers. O-ring ID from ø12 mm to ø300 mm, cross-section ø2 mm to ø5.33 mm.
Helical & Wave Springs
Helical spring — a coiled wire body that distorts under load and recovers its shape when released, for compressive or tensile duty. Closely coiled (helix angle under 10°) for compression; open coiled where the wire gap allows a larger helix angle. Supplied in passivated SS 302 (general corrosion resistance) and SS 316 (chloride / marine resistance), both rated up to 260°C.
Wave spring — a compression spring made of coiled flat wire with waves built in for spring effect. Occupies 30–50% of the compressed height of a round-wire spring with equal load, giving space savings and lower material cost. Built from a double filament of flat wire, welded together, in plain or squared-flat ends, standard in SS 304 / SS 316 hardened. Used in connectors, clutches, valves, pumps, seals and medical equipment.
Hard-Face & Wear Materials
- Silicon Carbide — industrial pump, mixer, agitator, cartridge and metal-bellow seals; a direct cross to John Crane and Burgmann faces used in petroleum, chemistry, refinery, paper, pharmacy and power industries.
- Ceramic — 99.5% high-alumina oxide, resistant to high temperature, corrosion and wear; chemically inert for spacecraft, machinery, metallurgy, printing, dyeing, foodstuff, pharmaceutical and textile use.
- Tungsten Carbide — high fractural strength, high thermal conductivity and small heat-expansion co-efficient; resists oil below 200°C, sewage water, weak acid, alkali resin and solids with impurity.
- Graphite — corrosion resistant, self-lubricating, low friction; rated to 200°C in neutral-to-acidic media, or 550°C oxidised / 400°C in neutral-to-alkaline media.
- Teflon (PTFE) — stable to 300°C (572°F), with good dimensional stability, reduced mould shrinkage and machinability for specialised chemical and industrial service.
Pumps & Separator Spares
Wear parts and spares for centrifugal pumps and separators — sleeves, gland plates, stuffing boxes, drive collars and casing wear rings — machined to the original drawing or to a sample supplied by your maintenance team.
Combine with our thermosyphon systems (SV-TS001) for double-seal buffer/barrier duty in line with API 682 guidelines: pressurises the buffer chamber, compensates leakage, cools the seal and signals low fluid level via an integrated level switch.
