Buffalo Pumps Inc. Asbestos Exposure: Navy Pumps, Gaskets, Packing & Claims
Buffalo Pumps and its predecessors have manufactured industrial and marine pumps in North Tonawanda, New York, for more than a century. Federal and state court records provide unusually strong product-specific evidence that historical Buffalo pumps were supplied with asbestos-containing gaskets and packing, particularly for U.S. Navy applications. Published decisions document machinists’ mates removing old packing and scraping or wire-brushing gaskets during routine pump maintenance.
Buffalo Pumps remains an operating pump business within Air & Liquid Systems Corporation, a wholly owned subsidiary of Ampco-Pittsburgh Corporation. Ampco-Pittsburgh’s current SEC filings continue to disclose asbestos personal-injury litigation involving asbestos-containing components historically used in products made by predecessors of Air & Liquid. No Buffalo Pumps-specific §524(g) asbestos personal-injury trust was confirmed; these liabilities continue to be addressed through litigation, settlements and applicable insurance rather than a dedicated Buffalo asbestos bankruptcy trust.
🏢 Buffalo Pumps Company History
Federal insurance litigation provides a detailed corporate history. Buffalo Steam Pump Company was incorporated in New York on November 28, 1896 and manufactured industrial pumps. Buffalo Forge Company acquired it in 1904. The pump company became Buffalo Pumps, Inc. in 1931, merged into Buffalo Forge in 1955 and continued as the Buffalo Pumps division. Later corporate transactions ultimately placed the pump operation within Air & Liquid Systems.

⚙️ Buffalo Pumps, Asbestos Gaskets & Packing
The historical asbestos evidence for Buffalo pumps is stronger than for many equipment manufacturers. In Braaten v. Saberhagen Holdings, the Washington Supreme Court summarized testimony from Buffalo Pumps’ corporate representative that Buffalo supplied pumps containing asbestos gaskets and packing from the 1940s into the early 1980s when specified. Other federal cases document Buffalo pumps supplied to the Navy with asbestos-containing gasket and packing materials.
Documented Historical Components
| Component / Equipment | Primary Court-Record Evidence |
|---|---|
| Industrial / centrifugal pumps | Buffalo and its predecessors manufactured industrial pumps; current Buffalo business remains focused on centrifugal pumps. |
| Internal packing | Multiple court records document historical Buffalo pumps supplied with asbestos-containing packing. |
| Internal gaskets | Multiple decisions document Buffalo pumps with asbestos-containing gaskets. |
| Replacement packing / gaskets | Federal litigation contains evidence that Buffalo sold asbestos-containing gasket and packing material to the Navy and supplied replacement parts. |
| Spare parts | Ninth Circuit evidence supported an inference that original Navy pumps could be supplied with spare asbestos-containing packing and gaskets. |
| External insulation | Pumps aboard ships could be insulated, but external insulation may have been installed by shipyards or supplied by other manufacturers and must be separately identified. |
Historical Asbestos-Use Evidence
| Issue | Verified Finding |
|---|---|
| Did historical Buffalo pumps contain asbestos components? | Yes. Published court records document asbestos-containing packing and gaskets in historical Buffalo pumps. |
| Documented period | Corporate testimony summarized by the Washington Supreme Court described asbestos-containing gaskets and packing from the 1940s through the early 1980s. |
| Did Buffalo manufacture the gasket and packing material itself? | Braaten states Buffalo did not manufacture the gaskets and packing included in its pumps. |
| Did Buffalo supply asbestos-containing components? | Yes. Court records contain evidence that Buffalo supplied pumps and, in some circumstances, replacement or spare asbestos-containing packing and gaskets. |
| Was every Buffalo pump identical? | No. Product configuration depended on specifications, model, application and period. |
| Later Navy asbestos specification | A record reproduced in U.S. Supreme Court briefing states that in 1987 a Navy order specified asbestos gaskets, but Buffalo was no longer using them and the customer supplied the gaskets. |
🔧 How Buffalo Pump Asbestos Exposure Occurred
Published Navy cases describe the maintenance process in detail. Workers pulled packing from pump stuffing boxes and removed old flange or internal gaskets using scrapers, wire brushes and sometimes power tools. If the packing or gasket contained asbestos, breaking or abrading it could create airborne debris in confined engineering spaces.
Documented Maintenance Exposure Pathways
| Task | Documented / Potential Exposure Mechanism |
|---|---|
| Removing pump packing | Hasenberg describes packing breaking apart as a worker pulled it with a hook-like tool. |
| Replacing flange gaskets | Workers used metal scrapers and wire brushes to remove old gasket material. |
| Wire-brushing gasket surfaces | Cunningham describes dusty gasket-removal work using wire brushes. |
| Grinding old gaskets | Cunningham describes difficult gaskets being ground out during Navy maintenance. |
| Repacking pumps | Routine pump maintenance could involve disturbing original or replacement packing. |
| Working nearby | Hasenberg describes engineering-space exposure while other sailors replaced packing and gaskets. |
| External insulation work | Insulation around pumps or piping could create separate exposure, but its manufacturer and supplier must be established independently. |
Asbestos-Related Health Conditions
| Condition | General Relationship to Asbestos |
|---|---|
| Mesothelioma | A rare cancer strongly associated with asbestos exposure; several published Buffalo Pump cases involve mesothelioma plaintiffs. |
| Lung cancer | Occupational asbestos exposure can increase lung-cancer risk. |
| Asbestosis | Progressive pulmonary fibrosis caused by inhaled asbestos fibers. |
| Pleural disease | Asbestos exposure can cause pleural plaques, thickening and other abnormalities. |
A Buffalo pump nameplate alone does not establish the asbestos content of every component or prove disease causation. The particular pump, component, date, maintenance history and claimant’s exposure must be evaluated.

📋 Buffalo Pumps Claim Evidence & Product Identification
Buffalo Pump litigation demonstrates the value of Navy machinery records, pump manuals, ship assignments, corporate testimony and firsthand maintenance evidence. A stronger investigation identifies the particular Buffalo pump and connects the claimant to work involving asbestos-containing original or replacement components.
Evidence That May Help Document Exposure
- Medical documentation establishing an asbestos-related disease.
- Navy service records, DD-214 records, ship assignments and rating history.
- Ship machinery lists and equipment records identifying Buffalo pumps.
- Buffalo pump nameplates, model numbers and technical manuals.
- Navy procurement specifications for gaskets and packing.
- Maintenance and overhaul records showing repacking or gasket replacement.
- Records identifying Buffalo-supplied spare or replacement components.
- Shipyard and employment records for civilian industrial exposure.
- Coworker testimony describing gasket scraping, grinding or packing removal.
- Evidence distinguishing Buffalo-supplied components from third-party replacement materials or external insulation.
Separate asbestos trust claims may also be available when a claimant encountered qualifying products made by bankrupt asbestos manufacturers in the same machinery spaces or workplaces. Those claims have independent medical and exposure requirements. Compensation is not guaranteed.
