Viking Pump and Asbestos-Containing Products

Company History

Viking Pump, Inc. is an American manufacturer of industrial rotary positive displacement pumps, headquartered in Cedar Falls, Iowa. The company has operated for decades as a supplier of pump equipment to a wide range of industrial sectors, including petroleum refining, chemical processing, food manufacturing, and marine applications. Viking Pump’s products became fixtures in heavy industrial environments across the United States, where rotary gear pumps and related fluid-handling equipment were essential to daily operations.

Throughout much of the twentieth century, Viking Pump competed in markets where industrial sealing, insulation, and packing materials containing asbestos were standard components. From the mid-twentieth century through approximately the early 1980s, pump equipment of the type Viking Pump manufactured commonly incorporated or was installed alongside asbestos-containing materials — including valve packing, gaskets, and insulation wraps — as a matter of industry-wide practice. These materials were valued for their ability to withstand high heat, chemical exposure, and mechanical stress under demanding operating conditions.

Viking Pump remains an active manufacturer today, operating as a subsidiary of IDEX Corporation. The company’s historical period of relevance to asbestos litigation generally spans the post-World War II industrial expansion through the early 1980s, when regulatory pressure and evolving product liability awareness led most equipment manufacturers to transition away from asbestos-containing components.

Asbestos-Containing Products

According to asbestos litigation records, Viking Pump equipment has been identified in legal proceedings in connection with asbestos-containing components associated with its pump systems. Plaintiffs alleged that Viking Pump rotary gear pumps and related fluid-handling equipment were manufactured, sold, or supplied with internal packing, gaskets, and sealing materials that contained asbestos.

Court filings document that the pump systems at issue in various cases typically required periodic maintenance involving the replacement or manipulation of asbestos-containing packing materials. In industrial pump applications of this era, valve and shaft packing made from braided or compressed asbestos fiber was a standard specification. Plaintiffs alleged that when workers removed, repacked, or serviced pump assemblies, they disturbed these asbestos-containing materials, generating respirable asbestos dust.

The specific product categories associated with Viking Pump in litigation records include:

  • Rotary gear pumps — internal rotary positive displacement pump assemblies used in petroleum, chemical, and industrial fluid transfer applications, which according to plaintiffs’ allegations contained asbestos shaft packing and internal gasket materials
  • Pump packing and seals — asbestos-containing gland packing and mechanical seal components alleged to have been specified or supplied as replacement parts for Viking Pump equipment
  • Associated gasket materials — flange gaskets and end-cover gaskets alleged to contain chrysotile or other asbestos fiber, used at connection points in pump assemblies

Plaintiffs alleged in court filings that Viking Pump either manufactured pumps with asbestos-containing internal components, specified the use of asbestos-containing replacement parts in service documentation, or both. According to litigation records, this practice was consistent with industry standards of the period, in which pump manufacturers routinely specified asbestos packing for high-temperature or chemical-service applications.

It should be noted that no independent determination of liability has been established in these matters as a general legal conclusion. The allegations described here reflect the claims asserted by plaintiffs in civil asbestos litigation and are presented as litigation history, not as adjudicated findings of fault.

Occupational Exposure

According to asbestos litigation records, the workers most frequently identified as having potential exposure to asbestos-containing materials associated with Viking Pump equipment include those employed in heavy industrial settings where rotary pump systems were in routine use. Court filings document that exposure claims have been asserted by individuals working in the following occupational categories:

Pipefitters and Millwrights — Workers responsible for installing, maintaining, and repairing industrial pump systems regularly handled packing and gasket materials. Plaintiffs alleged that re-packing pump shafts and replacing end gaskets required cutting, trimming, or removing asbestos-containing materials, activities that could generate airborne asbestos fibers in enclosed or poorly ventilated workspaces.

Machinists and Pump Mechanics — According to court filings, skilled tradespeople who serviced rotary gear pumps — including those who disassembled pump housings, cleaned mating surfaces of old gasket material, and installed replacement packing — were exposed to asbestos dust as a foreseeable consequence of routine pump maintenance.

Refinery and Chemical Plant Workers — Petroleum refineries, petrochemical plants, and chemical processing facilities were major users of rotary positive displacement pumps of the type Viking Pump manufactured. Plaintiffs alleged that workers at these facilities encountered Viking Pump equipment throughout their careers, often servicing the same pump stations repeatedly over periods of ten, twenty, or more years.

Marine and Shipyard Workers — Rotary pumps were widely used aboard vessels and in shipyard settings for fuel transfer, ballast, and fluid-handling applications. According to litigation records, Viking Pump equipment has been identified in shipyard exposure claims alongside other pump manufacturers whose products were present in naval and commercial shipbuilding environments.

Boilermakers and Insulation Workers — In some industrial settings, pump systems were insulated with asbestos-containing pipe covering or block insulation applied over or adjacent to pump assemblies. Court filings document allegations that workers who installed or removed thermal insulation near pump equipment faced cumulative asbestos exposure from multiple product sources simultaneously.

The latency period for asbestos-related diseases — the time between first exposure and clinical diagnosis — typically ranges from ten to fifty years. Workers who serviced Viking Pump equipment during the 1940s through the early 1980s may only now be receiving diagnoses of mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease. Family members of workers who carried asbestos dust home on their clothing or skin may also have been exposed through what is commonly referred to as secondary or take-home exposure.

Viking Pump is a Tier 2 manufacturer for purposes of asbestos litigation classification. This means that while Viking Pump has been named as a defendant in asbestos personal injury and wrongful death litigation, the company does not currently have an established bankruptcy-related asbestos trust fund through which claims can be submitted administratively.

According to asbestos litigation records, Viking Pump has been named as a defendant in civil asbestos cases filed in multiple jurisdictions. Court filings document that plaintiffs have asserted claims alleging exposure to asbestos-containing components associated with Viking Pump equipment. These cases have proceeded through civil litigation channels rather than through a trust fund claims process.

Because Viking Pump does not operate a Section 524(g) asbestos trust fund, individuals seeking compensation for asbestos-related illness connected to Viking Pump equipment must pursue their claims through traditional civil litigation. This typically involves filing a personal injury or wrongful death lawsuit in civil court, where the case is subject to jurisdiction-specific rules, statutes of limitations, and evidentiary standards.

Workers and families considering legal action should be aware of the following:

  • Statutes of limitations apply. The time allowed to file an asbestos claim varies by state and by the type of claim asserted. In most states, the limitations period begins to run from the date of diagnosis, not the date of exposure — but this rule is not universal. Consulting an attorney promptly after diagnosis is strongly advised.
  • Multiple defendants are common. Asbestos litigation rarely involves a single manufacturer. Workers who encountered Viking Pump equipment typically also encountered asbestos-containing products from other manufacturers present at the same jobsite. Claims are often filed against multiple defendants simultaneously.
  • Trust fund claims may apply for other exposures. Even when Viking Pump is identified as a source of exposure, co-exposures to products from manufacturers who have established asbestos trust funds — including well-documented defendants in the pump, gasket, and insulation sectors — may permit administrative trust fund claims to be filed in parallel with civil litigation.
  • Documentation of exposure history is critical. Employment records, union membership documentation, co-worker testimony, and product identification records are all relevant to establishing a claim. Attorneys experienced in asbestos litigation can assist in developing this exposure history.

Summary

Viking Pump, Inc. is a long-standing American industrial pump manufacturer whose rotary gear pump equipment was widely used in refineries, chemical plants, shipyards, and other heavy industrial settings from the mid-twentieth century through the early 1980s. According to asbestos litigation records, plaintiffs have alleged that Viking Pump equipment was manufactured or supplied with asbestos-containing packing, gaskets, and sealing components, and that workers who serviced this equipment were exposed to asbestos dust during routine maintenance activities.

Viking Pump does not operate an asbestos bankruptcy trust fund. Workers diagnosed with mesothelioma, asbestos-related lung cancer, asbestosis, or other asbestos-related conditions who have a history of working with or around Viking Pump equipment should consult an attorney experienced in asbestos litigation to evaluate their legal options. Civil litigation remains the primary avenue for seeking compensation from Viking Pump, and exposure to products from other manufacturers may support simultaneous trust fund claims through separate administrative channels.
