Ingersoll-Rand Steam-Driven Pumps with Asbestos Packing
Product Description
Ingersoll-Rand Company was one of the most prominent American manufacturers of industrial machinery throughout the twentieth century, producing a broad range of steam-driven pumps, compressors, turbines, and valves for heavy industry, power generation, shipbuilding, and petrochemical applications. Steam-driven pumps bearing the Ingersoll-Rand name were installed across virtually every sector of American industrial infrastructure — in naval vessels, refineries, chemical processing plants, paper mills, steel facilities, and municipal water systems.
These pumps were engineered to operate under sustained high-pressure, high-temperature conditions. Steam-driven pump assemblies typically included a steam end and a liquid end, connected by a central housing, with internal shafts and valve stems that required compression packing to create fluid-tight seals. Valve stem packing, mechanical seals, gaskets, and braided rope packing used throughout these systems were, for much of the twentieth century, manufactured from asbestos-containing materials or specified to require asbestos packing upon installation, maintenance, and repair.
Ingersoll-Rand pumps and related rotating equipment were shipped to industrial sites across the country. Because these machines required ongoing maintenance and periodic repacking as internal seals wore down, asbestos-containing packing materials were routinely handled not only during initial installation but throughout the operational life of the equipment — often spanning several decades.
Asbestos Content
The asbestos content associated with Ingersoll-Rand steam-driven pumps was not always integral to the pump castings themselves. Rather, asbestos was present in the ancillary sealing and packing materials that were integral to proper pump function. These included:
- Valve stem packing: Braided asbestos rope or compressed asbestos sheet packing used to seal rotating and reciprocating valve stems against steam and fluid leakage
- Gaskets: Flat asbestos sheet gaskets or spiral-wound gaskets with asbestos filler used at flanged connections, bonnet joints, and inspection ports
- Mechanical seals and pump packing rings: Asbestos-reinforced compression rings inserted into stuffing boxes to prevent leakage around pump shafts
Asbestos was favored for these applications because of its exceptional resistance to heat, pressure, and chemical degradation — precisely the conditions present in steam systems operating at elevated temperatures and pressures. Chrysotile, amosite, and crocidolite asbestos fibers were all used at various times in industrial packing and gasket products.
Plaintiffs in litigation have alleged that Ingersoll-Rand knew or should have known that the asbestos-containing packing and gasket materials specified for use with its steam-driven pumps would release respirable asbestos fibers during normal maintenance activities. Litigation records document that the company’s equipment documentation and engineering specifications referenced asbestos-containing replacement materials for stuffing boxes and valve assemblies.
How Workers Were Exposed
Exposure to asbestos from Ingersoll-Rand steam-driven pumps occurred primarily during maintenance, repair, and repacking operations rather than during passive equipment operation. Industrial workers who performed or worked near these tasks faced the greatest risk of fiber inhalation.
Repacking Operations: When pump shaft packing or valve stem packing wore out or began to leak, maintenance workers were required to remove old packing material and install new packing. This process involved cutting or pulling out compressed asbestos packing, which crumbled and released fine airborne fibers. New asbestos packing material was cut to length, braided, and compressed into stuffing boxes — further generating dust.
Gasket Removal and Replacement: Flat asbestos gaskets on flanged connections bonded tightly over time and required scraping, wire brushing, or grinding to remove. These activities released concentrated asbestos dust directly into the breathing zone of workers performing the task, as well as bystanders working nearby.
Cutting and Fitting Packing Materials: Maintenance workers routinely cut asbestos sheet packing or braided asbestos rope to fit specific pump configurations. Cutting asbestos sheet with knives or snips released fiber-laden dust without any protective enclosure or ventilation in most industrial settings of the mid-twentieth century.
Confined and Poorly Ventilated Spaces: Many industrial pump installations were located in enclosed pump rooms, engine rooms aboard ships, or basement mechanical spaces where natural ventilation was minimal. In these environments, airborne asbestos fibers generated during maintenance could linger for extended periods.
Litigation records document that industrial workers — including pipefitters, millwrights, machinists, stationary engineers, and general maintenance personnel — were exposed to asbestos during routine servicing of Ingersoll-Rand steam-driven pumps. Plaintiffs alleged that this exposure occurred repeatedly over the course of careers spanning years or decades, consistent with the cumulative, long-latency exposure profile associated with mesothelioma and asbestos-related lung disease.
Workers in petrochemical refineries, power plants, paper mills, steel mills, shipyards, and other heavy industrial settings where Ingersoll-Rand equipment was prevalent have been represented in asbestos litigation. Navy and maritime workers have also been significant claimants, given the widespread use of Ingersoll-Rand pumps aboard U.S. naval vessels and commercial ships.
Documented Trust Fund / Legal Options
Ingersoll-Rand is a Tier 2 litigated defendant. As of the time of this writing, Ingersoll-Rand has not established an asbestos bankruptcy trust fund. The company has instead defended asbestos claims in the tort system as a solvent defendant.
Civil Litigation: Litigation records document that Ingersoll-Rand has been named as a defendant in a substantial volume of asbestos personal injury and wrongful death lawsuits filed in state and federal courts across the United States. Plaintiffs alleged that Ingersoll-Rand manufactured or supplied steam-driven pumps that required asbestos-containing packing and gasket materials, and that the company failed to adequately warn workers of the associated health hazards. Claims have proceeded in jurisdictions including New York, New Jersey, California, Pennsylvania, Texas, and others with established asbestos litigation dockets.
Eligible Diseases: Claims associated with Ingersoll-Rand steam-driven pump exposure have included mesothelioma, lung cancer, asbestosis, and other asbestos-related diseases. Mesothelioma claims, given the disease’s near-exclusive association with asbestos exposure, have historically commanded the most significant attention in litigation.
Pursuing a Claim: Individuals diagnosed with an asbestos-related disease who worked with or around Ingersoll-Rand steam-driven pumps — or family members of deceased workers — should consult with an asbestos litigation attorney experienced in industrial equipment claims. Establishing a viable claim typically requires documentation of occupational history, product identification, and a confirmed diagnosis. Work history records, union records, employment files, co-worker testimony, and prior deposition records from related cases can all be relevant to demonstrating exposure.
Because asbestos-related diseases may develop 20 to 50 years after initial exposure, statutes of limitations vary by state and generally begin running at the time of diagnosis or discovery of the disease, not at the time of exposure. Timely consultation with qualified legal counsel is strongly recommended.
