Northern Pumps (McNally Industries) — Asbestos Product Reference

Company History

Northern Pumps was an American manufacturer of industrial pumping equipment operating under the broader corporate umbrella of McNally Industries. The company supplied pumps and related mechanical systems to heavy industrial sectors across the United States, with documented use of its equipment in facilities including power generation plants, chemical processing operations, oil refineries, and marine installations — industries that relied heavily on pump systems capable of withstanding extreme heat, pressure, and corrosive environments throughout the mid-twentieth century.

During the post-World War II industrial expansion through the late 1970s, Northern Pumps operated in a manufacturing environment in which asbestos-containing components were standard practice across the pump and rotating equipment industry. Asbestos gaskets, packing materials, and insulation were commonly integrated into pump assemblies either at the point of manufacture or during installation and maintenance at job sites. These materials were valued for their heat resistance, compressibility, and durability in high-temperature service environments.

Northern Pumps eventually came under the McNally Industries corporate structure, a parent organization with diverse industrial manufacturing interests. The company is understood to have ceased incorporation of asbestos-containing materials into its products approximately in the early 1980s, consistent with broader industry transitions driven by mounting regulatory pressure from the Environmental Protection Agency, the Occupational Safety and Health Administration, and evolving understanding of asbestos-related disease risk.

Asbestos-Containing Products

According to asbestos litigation records, Northern Pumps manufactured and supplied industrial pump equipment that incorporated asbestos-containing components during its period of active production spanning roughly the 1940s through the early 1980s. Court filings document allegations that asbestos-containing materials were present in various elements of the company’s pump assemblies, including internal packing, gaskets, and associated insulating components.

Plaintiffs alleged that pump packing — the compressible rope- or sheet-form material used to create seals around rotating shafts — frequently contained chrysotile or amphibole asbestos fibers in formulations manufactured during this era. According to asbestos litigation records, this type of packing was a standard component in centrifugal and reciprocating pump designs of the period, and workers who handled, installed, or replaced this packing were potentially exposed to airborne asbestos fibers during those tasks.

Court filings also document allegations involving asbestos-containing gaskets used to seal pump flanges, casings, and connection points. These flat gaskets, often composed of compressed asbestos fiber sheets bound with rubber or resin, were routinely cut, shaped, or disturbed during pump assembly and maintenance procedures — activities that plaintiffs alleged generated respirable asbestos dust.

It should be noted that the specific product designations, model numbers, and precise material compositions associated with Northern Pumps equipment have been the subject of ongoing litigation-based discovery. Workers and their representatives seeking detailed product identification information are encouraged to consult litigation records, deposition testimony from company representatives, or expert industrial hygiene analyses to establish specific product-level documentation relevant to individual exposure claims.

Occupational Exposure

According to asbestos litigation records, workers across numerous trades and industries encountered Northern Pumps equipment in conditions that plaintiffs alleged created significant asbestos exposure risk. The pump and rotating equipment sector presents a distinct occupational exposure profile because of the regular maintenance demands of pump systems — packing and gasket materials typically required periodic replacement, meaning that worker contact with these components was not limited to initial installation but recurred throughout the operational life of the equipment.

Court filings document claims from workers including:

Pipefitters and Steamfitters — These tradespeople installed, connected, and maintained pump systems in industrial facilities and aboard vessels. According to asbestos litigation records, plaintiffs in this occupational category alleged exposure during flanged connection work requiring gasket removal and replacement, as well as during general maintenance of pump assemblies.

Machinists and Millwrights — Workers responsible for the installation, alignment, and overhaul of industrial machinery, including pump systems, were alleged in court filings to have handled internal pump components including asbestos-containing packing materials in the course of normal maintenance activities.

Power Plant Workers — Power generation facilities were significant end-users of industrial pumping equipment. Plaintiffs alleged that boiler feed pumps, condensate pumps, and cooling water pumps at power stations incorporating Northern Pumps equipment contained asbestos components that were disturbed during regular maintenance outages.

Refinery and Chemical Plant Workers — Process industries that operated under high-temperature and high-pressure conditions relied extensively on robust pump systems. According to asbestos litigation records, workers at these facilities alleged repeated contact with asbestos-containing packing and gasket materials during routine pump turnarounds and emergency repairs.

Shipyard Workers and Merchant Mariners — Marine applications represented a historically significant market for industrial pump manufacturers. Court filings document allegations from shipyard workers and vessel crew members who encountered pump equipment containing asbestos components during construction, overhaul, and underway maintenance activities.

The exposure risk in these settings was compounded by the fact that pump maintenance frequently occurred in enclosed spaces — engine rooms, pump houses, basements, and machinery spaces — where ventilation may have been limited and airborne fiber concentrations could accumulate. According to asbestos litigation records, plaintiffs alleged that neither adequate warnings nor respiratory protective equipment were routinely provided to workers performing these tasks during the relevant decades.

Bystander exposure was also documented in litigation records. Workers present in the vicinity of pump maintenance activities — even those not directly handling asbestos-containing components — were alleged to have inhaled fibers released during packing replacement, gasket cutting, and related tasks.

Trust Fund / Legal Status

Northern Pumps, operating under McNally Industries, is classified under Tier 2 for purposes of asbestos liability reference on this site. This classification reflects that asbestos-related litigation has been filed against the company or its corporate predecessors and affiliates, but that, as of the time of this writing, no dedicated asbestos bankruptcy trust fund has been established under Section 524(g) of the U.S. Bankruptcy Code attributable to Northern Pumps or McNally Industries.

According to asbestos litigation records, claims involving Northern Pumps equipment have proceeded through the civil tort system. Plaintiffs have alleged that the company’s pump products contained asbestos-bearing components and that inadequate hazard warnings contributed to occupational disease. Court filings document that such claims have been litigated in multiple jurisdictions, though the outcomes of individual cases vary and no liability should be understood as judicially established as a general matter based on this reference material.

Because no dedicated trust fund exists for this manufacturer, individuals with potential exposure claims involving Northern Pumps or McNally Industries equipment would generally need to pursue compensation through direct civil litigation rather than a trust claim submission process. This distinction is practically significant: trust fund claims typically involve a defined claims administration process with published disease criteria and scheduled values, while civil litigation involves individual case filing, discovery, and negotiated or adjudicated resolution.

If you or a family member worked in a trade or industry where Northern Pumps or McNally Industries equipment was used — particularly in power generation, petroleum refining, chemical processing, marine, or heavy industrial settings — and have received a diagnosis of mesothelioma, asbestosis, lung cancer, or another asbestos-related disease, the following points are relevant to understanding your options:

  • No dedicated asbestos trust fund is currently associated with Northern Pumps or McNally Industries, meaning claims cannot be submitted to an established trust administrator.
  • Civil litigation has been the documented avenue for claims involving this manufacturer. An attorney experienced in asbestos litigation can evaluate whether Northern Pumps equipment can be identified in your work history and whether a viable claim exists.
  • Product identification is an important step. Documentation such as employment records, union records, facility equipment inventories, co-worker testimony, and expert industrial hygiene review can help establish specific product-level exposure.
  • Other responsible parties may exist. In cases involving multiple manufacturers of pumps, gaskets, packing, and insulation products used at the same worksite, claims against other parties — some of whom may have established trust funds — can often be pursued simultaneously.
  • Statutes of limitations apply to asbestos personal injury and wrongful death claims and vary by state. Consulting with an asbestos attorney promptly after diagnosis is strongly recommended to preserve legal rights.
