Published

Industrial supply chains are supported not only by high-tech components like chips and lasers, but also by a massive layer of infrastructure that provides precise measurements and the delivery of materials and semi-finished products to factories, processing plants, etc.

For these tasks, pumps, meters, injectors, valves, and other such components are essential, as almost all industrial processes require at one point or another the handling of material in a liquid form. This is true for “old” industries like car factories and chemical plants, as well as advanced tech sectors like data centers, biotech, aerospace, etc.

This equipment and these parts need to be highly reliable, as any failure can lead to production interruptions, contamination, or even catastrophic incidents.

Which is why the sector is controlled by highly specialized manufacturers that have decades of experience in how to make cheaply enough the most reliable and efficient liquid-handling tools.

A good example is IDEX Corporation, a specialist in pump and liquid measuring tools, selling to fire departments, manufacturers, pharmaceutical companies, etc.

IDEX Corporation Overview

IDEX Corporation History

IDEX was founded in 1988 with the acquisition of several industrial divisions of an industrial conglomerate, Houdaille Industries. It immediately IPOed in 1989, with its name standing for “Innovation, Diversity, and Excellence”.

The company then grew through a series of acquisitions, notably in 1994 with  Hale Products selling fire-trucks, portable pumps, and ventilation systems, which are still a core part of today’s IDEX product lines.

It also includes IDEX’s acquisition of Gast Manufacturing of Benton Harbor in 1998, producing compressors, vacuum pumps, air motors, deepening the expertise in pumps, this time in air handling instead of liquids.

Further useful patents or specific designs were acquired in 2018 with the purchase of Phantom Controls and Airtech in 2021.

In the 2010s and 2020s, IDEX kept this idea of a core of expertise in pumps, valves, and compressors, but expanded through acquisitions in several new industries. For example, it acquired Microfluidics International in 2011 to enter the pharmaceutical market, Abel Pumps LP in 2018 to enter the maritime and power industries, Muon Group in 2022 for more micro-precision technology, and Mott Corp in 2024 to add filtration to its pharmaceutical, biotech & science segment.

Besides the new market, some acquisitions have also been made to boost the quality and independence of in-house manufacturing. For example, the company acquired STC Material Solutions in 2023 to get access to essential technical ceramics and hermetic sealing products used in its ultra-pure fluidics systems.

In total, just in 2020-2025, a dozen companies were acquired for a total of $3B to expand the client pool and technology base.

IDEX Organisation

In total, today’s IDEX is made of more than 50 largely decentralized businesses that operate as subsidiaries, making it a typical successful industrial conglomerate.

This model allows the company to combine deep niche expertise and sales presence while also sharing across department patents, R&D, overhead, IT, and manufacturing facilities.

IDEX’s  “highly engineered components”, centered around the company’s “pumping and moving fluids” core engineering expertise of the company’s, are organized around 3 main segments:

  • Fluid & Metering Technologies (FMT): pumps, valves, flow meters, injectors, and flow monitoring, for the chemical, general industrial, water & wastewater, agriculture, food, and energy industries.
  • Health & Science Technologies (HST): Precision fluidics, rotary pumps, displacement pumps, roll compaction, and drying systems used in beverage, food processing, pharmaceutical, and cosmetics.
  • Fire & Safety + Diversified (FSDP):
    • Truck-mounted and portable fire pumps, stainless steel valves, foam and compressed air foam systems, rescue tools, and water distribution for fire control and fire responders.
    • High-heat-resistant fastening solutions for critical automotive components.
    • Equipment for dispensing, metering, and mixing colorants and paints.

Sales are coming half from the USA and 1/4th from Europe, with Health & Science Technologies and Fluid & Metering Technologies the two largest segments.

IDEX By The Numbers

With almost 9,000 employees, IDEX is a reasonably sized conglomerate, with its decentralized structure helping keep lean and efficient.

The strategy of the company is to hold the #1 or #2 position in its industrial niche for most of its business units, giving it economies of scale, reputation, and higher margins.

As of 2026, IDEX protects its innovations through a massive IP library of more than 1,500 active global patents.

This decentralization is reflected in IDEX’s global presence, with manufacturing sites in 20 countries, a direct footprint in 24 countries, although high-end R&D and advanced component production remain heavily anchored in the US and Europe. It is expanding quickly in new or emerging markets, achieving a 6% to 8% growth in emerging markets, in part thanks to expanded hubs in Dubai, India, and Singapore.

IDEX’s customer base is highly diversified, with more than 1,200+ global customers.

In 2025, IDEX made $3.45B in revenues, $483M in net income, and $616M in free cash flow. Currently, this cash flow is partially used to pay off debt (total non-current liabilities of $2.3B), after the $1B acquisition of Mott Corp in 2024. IDEX is also characterized by high operating margins, consistently hovering around 22-26%.

IDEX Businesses

Health & Science Technologies

This is the largest segment of the company, with $1.5B in sales in 2025, which serves industries like pharmaceutical & biotech, semiconductor manufacturing, food processing, cosmetics, etc.

This is a very quickly growing segment, with 7% CAGR in revenues between 2021 and 2025.

A key reason for this quick growth has been co-development with market-leading OEMs (Original Equipment Manufacturers), where IDEX brings its expertise in microfluidics, laser, air pumps, etc., to its partners when producing new DNA sequencers, mass spectrometers, and semiconductor tools.

Once a component is embedded into a regulated device (for example, an FDA-approved medical system), replacing the supplier requires costly re-certification, locking in multi-decade revenues for IDEX.

The importance of OEMs is also reflected in the acquisition strategy, where IDEX will target products that are deeply embedded in customer architectures.

The company has many subdivisions and brands in this sector, but all are supported by the same underlying technologies and corporate infrastructure.

This is by far the most technologically advanced segment, both in terms of products and customers. Today, the AI boom is helping IDEX grow further, beyond its historical position in biotech, with silicon wafer manufacturing, telecommunication, and even aerospace applications growing quickly.

Fluid & Metering Technologies

This segment is roughly divided between municipal and industrial waters (21%) and diversified industrial applications (79%), and made $1.2B in sales in 2025. It grew by 5% CAGR between 2021 and 2025.

The largest segment in this department is pumps (35% of sales), water handling (29%), and energy applications (17%).

This department in particular is growing quickly abroad, notably in India, the Middle East, and Southeast Asia. It is also made of many well-respected brands in its respective niches.

A future source of margin growth and competitive advantage is the ongoing digitization of sales, fulfillment, and maintenance tasks.

Fire & Safety + Diversified

This segment is the smallest of the three, made up of half by sales to fire departments, which include water pumps and valves, but also rescue systems like the “jaws of life” hydraulic tool for the extraction of people from traffic wrecks.

The rest of the activity is paint spraying and colorant mixing (20%) and other industrial applications like high-heat-resistant fastening solutions for critical automotive components.

With “only” 3.5% CAGR increase in sales, this is also more of a legacy, stable business. It nevertheless brought 28.7% of total EBITDA in 2025, making it a “safe” source of revenues compared to the other segments, which are growing more quickly, but also require more investment and might prove to be cyclical in the long term.

IDEX Corporation Strategic Position

Industrial conglomerates tend to fit into two categories: lean, efficient, industry-dominating companies; or bloated, unfocused, and excessively indebted giants with clay feet.

Usually, the defining factors to determine if a conglomerate is actually efficient are the following:

  • Focus on either one industry or one technology, letting it harvest synergy in network & sales or R&D/manufacturing, respectively.
  • Decentralized structure, letting its department do their job while still providing useful support for cross-selling and overhead.
  • Reasonable level of debt, letting it handle a downturn without collapsing or having to sell the most valuable segments of the company.
  • Access to deep capital markets and low rates for the financing of acquisitions is why the industrial conglomerate is a quintessential American archetype.

By concentrating on a defined technology set (liquid and air handling) with a very wide range of applications, IDEX has been building a durable competitive advantage in this industrial niche. The company has dubbed this method the “big fish in a small pond” strategy.

In theory, many of its customers might not even be aware that the expert supplier they deal with is part of a larger conglomerate. This is especially true as the culture and practice of acquired companies, already successful in their own field, are generally preserved intact by IDEX’s management.

But in practice, they see the result in better IT systems, higher manufacturing expertise, and advanced capacity financed by shared R&D and overhead costs.

IDEX is well-positioned to keep growing relatively quickly, thanks to its position as an essential supplier to semiconductor and pharmaceutical manufacturing, scientific tooling, especially thanks to a series of key strategic acquisitions done in the past 5 years that reinforce its position in these markets.

And with a reasonable level of debt compared to free cash flow, as well as growing revenues, the company seems solid from a financial standpoint.
