Lamot

What Lamot does

LaMOT Disc Products manufactures engineered rupture discs and rupture disc holders — critical safety pressure relief devices used across industrial facilities worldwide. Its product portfolio spans eight rupture disc designs (STD, LD, LDV, LDV-G, LPL, LPLV, IS, and a screw-type/throwaway variant) covering burst pressures from 2 to 15,000 psig and operating temperatures up to 1,000°F, paired with five holder configurations (full bolted, insert, union type, throwaway, and screw type) and complementary accessories including the proprietary B.D.I. Burst Disc Indicator and BDI-FLX Burst Disc Sensor System. All manufacturing is performed under an ISO 9001 Quality Assurance System, with state-of-the-art pressure and tolerance testing applied to every disc produced. The company emphasizes proprietary designs such as seven-hole non-fragmenting composite discs and integrated vacuum supports, supported by an ASME-accepted flow testing laboratory.

LaMOT operates as a subsidiary brand of Continental Disc Corporation (CDC), which acquired LaMOT Corporation in 1990; CDC itself is now part of Baker Hughes, a diversified energy technology conglomerate. The business is headquartered in Liberty, Missouri, where CDC originated in 1965; the LaMOT product line traces its manufacturing heritage to 1964. The CDC parent employs more than 300 people globally and serves more than 40 industries including aerospace and defense, pharmaceutical and biotechnology, water purification, chemical processing, and oil and gas. International reach is provided via direct offices in the Netherlands (established 1983), India, and China, supplemented by a global sales representative network.

Revenue is generated through custom quote-based hardware sales of discs, holders, and accessories under multi-year contract cadence, with no public pricing. Go-to-market is sales-led and enterprise-oriented: outside field sales engage engineering, procurement, and operations teams at industrial facilities, supported by an inside sales and customer service department and a Request-a-Quote entry point on the company website. The customer base is diversified across 40+ industries with no publicly disclosed anchor-customer concentration. CDC also owns GROTH Corporation (acquired 1999) and LaMOT Valve & Arrestor (formed 2017), creating a sibling portfolio spanning rupture discs, low-pressure relief valves, flame and detonation arrestors, and upstream safety products.

Revenue model

1. Rupture Disc Sales: LaMOT Disc Products manufactures and sells rupture discs (safety relief devices) and associated holders and accessories. The primary revenue stream is the sale of engineered pressure relief products to industrial customers across multiple sectors. The company operates with agile manufacturing practices to minimize downtime for customers.
2. Rupture Disc Holder Sales: Sales of rupture disc holders (full bolted, insert, union type, throwaway, screw type) that pair with LaMOT rupture discs. Holders meet the same exacting standards as the discs, with accurate tolerances, tight seals, ease of use, and simple maintenance.
3. Accessories and Sensor Systems: Sales of accessories including B.D.I. Burst Disc Indicators, BDI-FLX Burst Disc Sensor Systems, protective liners, vacuum supports, gaskets, and other support tools. These products complement the core rupture disc and holder offerings.

Core offering

LaMOT Disc Products manufactures industrial rupture discs, rupture disc holders, and complementary accessories for overpressure protection. Rupture discs are engineered safety devices that burst at predetermined pressures to provide instantaneous full-flow relief in vessels and piping systems, while the holders and accessories (including B.D.I. indicators and BDI-FLX sensors) support installation and monitoring. Products are sold to industrial buyers across chemical processing, oil and gas, pharmaceutical, aerospace and defense, water treatment, and more than 40 other industries.

Product overview

LaMOT Disc Products manufactures industrial rupture discs and holders as physical pressure relief equipment. The product portfolio centers on two core product lines: rupture discs (including STD, LD, LDV, LDV-G, LPL, LPLV, and IS models) designed to provide instantaneous overpressure protection by bursting at predetermined pressures, and rupture disc holders (including Full Bolted, Insert, Union Type, Throwaway, and Screw Type holders) that house and support the discs. A complementary line of accessories includes the B.D.I. Burst Disc Indicator and BDI-FLX Burst Disc Sensor System for monitoring disc status. All products are manufactured under ISO 9001 quality assurance standards and the company is now part of Baker Hughes (via parent company Continental Disc Corporation).
