Semler Industries

What Semler Industries does

Semler Industries is a third-generation, family-owned industrial equipment manufacturer and value-added distributor headquartered in Franklin Park, Illinois. Founded around 1905, the company has operated for over a century and now serves more than a dozen industrial verticals including aviation, petroleum, pharmaceuticals, power generation, chemicals, food and beverage, electronics, and waste water. Its core offering spans four product groups — Core Distributed Products, Equipment Solutions, Aviation Services, and Functional Engine Fluids — plus a Fuels portfolio covering transfer, dispensing, blending, polishing, and power generation fuel systems.

The company's technology base combines distribution of third-party components (pumps, meters, hose reels, tanks, filters) from industry-leading manufacturers with in-house engineering and fabrication for custom-configured, turn-key liquid handling systems. Notable proprietary or branded offerings include the PetroPolisher stationary fuel maintenance systems for standby power applications, DEF transfer systems for Tier 4 generator SCR systems, and AWOCS aviation water overflow warning and containment systems. The product catalog also includes a broad aviation ground support line (potable water cabinets, glycol de-icing, filtration, and fixed-base operation fuel systems) and a deep functional engine fluids line covering DEF, lubricants, glycol, ATF, and other specialty fluids.

Commercially, Semler runs a sales-led, B2B industrial model using a regional representative network organized by state and product group, with direct enterprise sales supported by a downloadable resource library and news/content marketing. Revenue is generated primarily through hardware sales of distributed components and one-time project revenue from custom system manufacturing, supplemented by aftermarket and technical support services. Pricing is quote-based rather than publicly listed. The business is privately held with no disclosed funding rounds or parent company, and the family-owned structure has been preserved across three generations. In January 2025 the company expanded its footprint with a new 20,000-square-foot distribution center adjacent to its headquarters, consistent with a modest capacity buildout.

Direct peers

• Graco: Graco is a leading global manufacturer of fluid handling systems, pumps, and spray equipment for industrial and contractor markets. It directly competes with Semler in pumps, meters, and dispensing equipment, and serves overlapping industries including lubricants, DEF, and industrial fluids with a much larger global footprint.
• Gorman-Rupp Industries: Gorman-Rupp designs, manufactures, and sells pumps and fluid handling systems for industrial, municipal, and petroleum markets. The product overlap with Semler's pump assemblies, filtration, and custom fluid systems — particularly in petroleum and aviation fuel handling — makes it a direct comparable.
• Franklin Electric: Franklin Electric manufactures pumps, fueling systems, and fluid management equipment with strong positions in fueling, water systems, and industrial fluid handling. Its fuel and DEF system businesses overlap directly with Semler's PetroPolisher, DEF transfer, and fuel handling portfolios.
• Velcon Filters: Velcon Filters specializes in aviation and industrial fuel filtration systems, including fuel polishing and filtration vessels for airports and power generation. Its product line and customer base in aviation fuel handling overlap directly with Semler's PetroPolisher and aviation filtration offerings.

Broad incumbents

• IDEX Corporation: IDEX is a diversified fluidics and engineered industrial products platform owning multiple pump, dispensing, and filtration brands. While broader and more acquisitive than Semler, IDEX's business units (e.g., dispensing, fluid handling, filtration) compete with Semler's core product groups and serve many of the same verticals.
• Xylem: Xylem is a major water and wastewater technology company offering pumps, filtration, and treatment systems. Its industrial and commercial water handling portfolio overlaps with Semler's power generation cooling water, waste water, and chemical processing applications, though Xylem operates at much greater scale.
• Flowserve Corporation: Flowserve manufactures pumps, valves, seals, and automation services primarily for the petroleum, power, and chemical industries. It competes with Semler on pumps and engineered fluid systems in petroleum and power generation, though at a significantly larger scale and with broader geographic reach.
• Watts Water Technologies: Watts Water designs and manufactures water and fluid management products including pumps, filtration, and storage solutions across plumbing, industrial, and water quality markets. It is comparable to Semler on fluid storage, filtration, and water handling but at much greater scale and brand recognition.

Others

• Facet (Purolite / Facet Filtration): Facet is a documented Semler technology partner supplying filtration products integrated into Semler's aviation ground support equipment. As a named supplier, it is comparable to Semler on aviation filtration technology but plays an upstream/OEM role rather than direct competitor.
• Hannay Reels: Hannay is a documented Semler channel partner manufacturing industrial hose reels that Semler distributes. The two companies are comparable on hose-reel product lines but Hannay plays a supplier role rather than competing for system-level custom fabrication work.
