Seven ranges. One works floor.
Every family below is designed, machined, assembled and tested at our Jogeshwari works — so the seal you fit is the seal we stood behind.

Six commitments that print on every batch — the way we design, the way we test, the way we deliver.
Unbalanced & balanced, for every rotating asset
Mechanical seals for pumps, compressors, blowers, reactor vessels and agitators — covering chemical, pharmaceutical, refinery, petrochemical, gas, oil, textile, dairy and shipping duty.
Round-the-clock, all over India
Engineers with deep field experience of mechanical seals, support systems and rotating equipment — trained to identify root cause quickly and accurately.
Every seal, pressure & leak tested
Raw material sourced in India and imported globally. Continuous improvement programs so each employee does the job right — first time, every time.
Consistent, accurate, on time
Committed to meeting customer needs and expectations by performing the task consistently and accurately, shipment after shipment.
One floor, one standard
Design, development and quality control work as a single team — encouraging and supporting each other toward shared goals.
Customised to outperform
Designs refined against customer feedback to perform on par with the more expensive international seal brands.
From duty spec to tested seal.
One enquiry, four steps — and a seal that's already been pressure and leak tested before it's packed.
Send the duty
Shaft size, pressure, speed, temperature and media — either from a pump nameplate or your existing part number.
Engineers spec it
We cross it to a Sil-Vex family, or design a custom seal to your drawing — face materials chosen for the medium.
Manufacture & test
Machined on our floor, assembled, then pressure and leak tested before dispatch. Zero defect is the exit standard.
Ship & support
Delivered on time across India, with 24×7 field support if a seal ever needs to be diagnosed on-site.
Five materials, engineered for the medium.
The wrong face fails fast. We match the face pair to your process — that's where seal life is won.
Silicon Carbide
Industrial pump, mixer, agitator & cartridge seals — a direct replacement for John Crane and Burgmann faces.
Ceramic
99.5% high-alumina, chemically inert seats for spacecraft-grade hardness across food and pharma duty.
Tungsten Carbide
High fractural strength and thermal conductivity — resists oil below 200°C, sewage water and weak acid.
Graphite
Corrosion-resistant, self-lubricating faces rated to 200°C neutral / 550°C oxidised atmosphere.
Teflon
Stable to 300°C with low mould shrinkage — machined for specialised chemical service.
