Engineered Reliability For Critical Industrial Applications

Headquartered in Goregaon East, Mumbai, MECH-SEAL ENGINEERING (INDIA) PVT. LTD. has grown into a premiere manufacturer of fluid sealing solutions since its inception in 1978. We engineer high-reliability mechanical seals designed to prevent toxic emissions, eliminate costly fluid loss, and maximize uptime in demanding process environments.

Our product range includes single and double cartridge seals, agitator & reactor seals, welded metal bellow seals, PTFE bellow seals, component seals, seal support systems (API Plan 52, 53A, 53B, 53C, 54), and equivalent replacement seals for major global brands including Burgmann, John Crane, Chesterton, and Flowserve.

API 682 Compliance

Fully compliant with international refinery and chemical sealing standards.

Custom Retrofitting

Fast turnaround on custom dimensions and reverse-engineered import replacements.

Guiding Principles & Corporate Values

Driven by engineering integrity, continuous research, and customer-first commitment.

Our Vision

To be a recognized global leader in fluid sealing technology by engineering leak-free solutions that protect human life, safeguard industrial assets, and promote environmental sustainability.

Our Mission

To manufacture high-precision mechanical seals using advanced metallurgy, state-of-the-art optical lapping, and rigorous quality testing while delivering unparalleled technical support and rapid delivery worldwide.

Quality Policy

We commit to 100% defect-free manufacturing through strict adherence to ISO 9001:2015 protocols, material certification (MTC 3.1), and comprehensive pre-dispatch pressure testing.

Infrastructure & R&D

State-of-the-Art Manufacturing & Quality Lab

Equipped with modern CNC machining centers, precision optical lapping equipment, dynamic testing rigs, and helium mass spectrometer leak detectors.

CNC Precision Turning

Multi-axis CNC turning and milling centers ensuring micron-level machining tolerances on Hastelloy, Inconel, Titanium, and Stainless Steel components.

Optical Lapping Lab

High-precision monochromatic light inspection and optical lapping machines achieving seal face flatness within 1 to 2 helium light bands (0.3 - 0.6 µm).

Dynamic & Static Hydro Test Rigs

In-house automated test benches simulating operational pressures up to 150 bar, shaft speeds up to 10,000 RPM, and thermal cycles before customer dispatch.

Advanced Seal Face Materials

Premium grade Reaction Bonded Silicon Carbide (RBSiC), Sintered Silicon Carbide (SSiC), Tungsten Carbide (6% Ni), Carbon Graphite, and Ceramic faces.

Secondary Seal Elastomers

Wide inventory of Viton (FKM), Aflas, Kalrez (FFKM), EPDM, PTFE, and GFT for aggressive chemical compatibility.

Seal Reconditioning & Refurbishment

Complete re-lapping, face replacement, elastomer overhaul, and pressure re-testing of imported mechanical seals at fraction of replacement cost.
