What Isomag does
ISOMAG Corporation is a privately held industrial manufacturer founded in 1994 by Steve Dawson and headquartered in Baton Rouge, Louisiana. The company designs and produces magnetic-face bearing isolators — patented non-contacting seals that use magnetic energy to create a positive, liquid-tight closure on the bearing housings of rotating equipment. The technology is protected by US patents 5,730,447 and 6,805,358, and the seals are rated for up to 75,000 hours of operating life at surface speeds up to 15,000 surface feet per minute, exceeding standard L10 bearing life and outperforming traditional lip seals and labyrinth isolators in both dynamic (rotating) and static (shutdown) conditions. The product portfolio is concentrated on the magnetic-face bearing isolator line, available in variants such as V7-UL and RSA seals, with custom engineered units delivered in as little as 48–72 hours for specific application parameters (shaft diameter, bore, equipment type, orientation, lubrication, and speed).
ISOMAG sells primarily to large industrial enterprise end-users across oil & gas refining, chemical processing, pulp & paper, power generation, food & beverage, mining, marine, wind energy, and people-mover/elevator sectors. Named customers include BASF, Shell, Chevron, Exxon, DuPont, Dow Chemical, LyondellBasell, Marathon Petroleum, PBF Energy, Suncor, Phillips 66, International Paper, Anheuser-Busch, Tyson Foods, Ameren Illinois, NOV, and Shintech. Pricing is quote-based and application-specific, with no public price list; engagement is driven by the website's Request a Quote form, direct phone/email contact, and a regional Asia contact (Felix Xu, China).
The business model is custom-engineered hardware sales with aftermarket replacement revenue, sold through direct enterprise field sales, industrial equipment distributors, manufacturer representative networks (including John Crane), and OEM specification channels where reliability engineers specify ISOMAG on equipment repair and rebuild projects. Go-to-market relies on a deep library of technical content, case studies, industry association memberships (ANSI, Hydraulic Institute, AGMA, ISO, EnergyAPI), and a small digital presence (LinkedIn, YouTube). The company has remained privately held and founder-led for 30 years without external funding rounds or acquisitions, and has a single manufacturing/office site in Baton Rouge supplemented by a regional Asia contact.

Revenue model
- Magnetic Bearing Seal / Isolator Product Sales: ISOMAG generates revenue through the manufacture and sale of magnetic-face bearing isolators and seals for rotating equipment. Products are sold directly to end-user industrial companies and through distributor/reseller networks. The company also earns revenue from custom engineering and manufacturing of bespoke seals for specific equipment applications, with turnaround times as fast as 48-72 hours for custom orders.
- Aftermarket Replacement Parts and Upgrades: Ongoing revenue from replacement seal orders as existing customers upgrade multiple pieces of rotating equipment. BASF's Geismar site has maintained thousands of upgraded pumps and gearboxes, with annual spend under $30K per year for over ten years on seal replacements.

Isomag product offering
Product offeringCore offering
ISOMAG designs, manufactures, and sells patented magnetic-face bearing isolators (bearing seals) used on rotating industrial equipment such as pumps, gearboxes, electric motors, blowers, and steam turbines. The seals use magnetic energy to provide liquid-tight, non-contacting protection in both dynamic and static operating conditions, extending bearing life up to 75,000 hours and operating at speeds up to 15,000 surface feet per minute. ISOMAG also provides custom engineered seal solutions with rapid 48-72 hour turnaround for application-specific orders.
Product overview
ISOMAG offers a focused portfolio centered on its patented magnetic-face bearing isolator technology. The core product is the Magnetic-Face Bearing Isolator, available in variants such as V7-UL seals and RSA seals. These non-contacting, positive-seal devices are designed for bearing protection across rotating equipment including electric motors, gearboxes, pumps, and steam turbines. The product line serves diverse industrial applications from oil & gas and chemical processing to pulp & paper, power generation, mining, marine, and food processing. ISOMAG's magnetic sealing technology replaces traditional lip seals and labyrinth isolators, providing liquid-tight sealing in both dynamic and static operating conditions with a guaranteed 5-year life typically extending to 10+ years.
