Buffalo Industrial Process Pumps

Product Description

Buffalo Pumps manufactured a line of industrial process pumps used extensively across heavy industry in the United States throughout much of the twentieth century. These pumps were engineered to handle demanding applications, including the movement of hot fluids, corrosive chemicals, and high-pressure process streams in environments such as petroleum refineries, chemical processing plants, power generation facilities, shipyards, and manufacturing operations.

As workhorses of industrial infrastructure, Buffalo process pumps were built to operate continuously under extreme thermal and pressure conditions. The mechanical demands of these applications required that pump components be assembled with materials capable of withstanding heat, vibration, and chemical exposure. In practice, this meant that asbestos-containing materials were commonly integrated into pump assemblies and the systems surrounding them — either as part of the original pump construction or as standard maintenance components applied by the workers who installed and serviced the equipment over its operational lifetime.

Buffalo Pumps developed a reputation for durability in heavy industrial sectors, and their equipment was often specified by engineers and procurement departments working on large-scale industrial projects. As a result, Buffalo process pumps were installed across a wide range of facilities, and workers in those facilities encountered them routinely over the course of careers that could span several decades.

Asbestos Content

Litigation records document that Buffalo industrial process pumps were associated with asbestos-containing components in several forms. Plaintiffs alleged that asbestos materials were present in pump packing, gaskets, and insulation products that were applied to or used in conjunction with these pumps.

Pump packing — braided or compressed material inserted into stuffing boxes to create seals around rotating shafts — was commonly manufactured with asbestos fibers during the mid-twentieth century. Asbestos packing was valued for its ability to withstand high temperatures and its resistance to chemical degradation, making it a preferred material in exactly the kinds of high-heat, high-pressure environments where Buffalo pumps were deployed.

Gaskets sealing flanged connections, valve bodies, and casing joints were similarly produced using asbestos-containing compounds. Compressed asbestos sheet gaskets, spiral-wound gaskets with asbestos filler, and ring-style gaskets cut from asbestos board were all in common industrial use during the periods when Buffalo process pumps were actively installed and serviced.

Beyond the internal components, the exterior surfaces of pumps and associated piping systems in high-temperature service were frequently covered with asbestos insulation blankets or pre-formed pipe insulation. Plaintiffs alleged that this insulation was applied by tradespeople working in close proximity to the pumps themselves, further concentrating asbestos fiber release in the immediate work area around the equipment.

How Workers Were Exposed

Industrial workers generally encountered asbestos-related hazards associated with Buffalo process pumps through the full lifecycle of the equipment — installation, routine maintenance, repair, and eventual removal or replacement.

During installation, workers fitting pumps into process lines handled asbestos packing and cut gasket material to size. Cutting sheet asbestos gaskets to fit flanges was a task that generated airborne dust, and workers performing this work in enclosed mechanical rooms or below-deck spaces on vessels did so without adequate respiratory protection during much of the twentieth century.

Routine maintenance presented perhaps the most sustained exposure opportunity. Process pumps require periodic repacking of stuffing boxes as the packing material wears and loses its sealing effectiveness. Workers performing repacking tasks removed old asbestos packing — often dried, friable, and prone to crumbling — by hand or with picks and scrapers. Plaintiffs alleged that this removal process released significant concentrations of asbestos fibers into the breathing zone of the worker performing the task and any colleagues working nearby.

Gasket replacement followed a similar pattern. Removing a used gasket from a flanged pump connection required scraping or grinding away the compressed material that had bonded to the metal surfaces over time. Litigation records document that this scraping process was a recognized mechanism of asbestos fiber release in industrial settings.

Workers in refineries, chemical plants, power stations, and maritime facilities also faced what is sometimes described as bystander exposure — situations in which a tradesperson working in a different capacity was present in the same space while pump maintenance was underway. Electricians, pipefitters, and other tradespeople working in the vicinity of pump maintenance were potentially exposed to fibers generated by colleagues performing packing or gasket work.

Thermal insulation work added another dimension to exposure risk. In facilities where pumps and connected piping were heavily insulated, insulation workers applied and removed asbestos lagging in the same physical spaces occupied by process equipment including Buffalo pumps. Disturbance of aged asbestos insulation during repair or replacement work released fibers into the surrounding area.

Because asbestos-related diseases — including mesothelioma, asbestosis, and lung cancer — have latency periods that can extend for decades following initial exposure, many workers did not develop symptoms until long after the period of heaviest industrial asbestos use had ended. This latency has meant that claims relating to Buffalo process pump exposure have continued to emerge well into the twenty-first century.

Documented Trust Fund / Legal Options

Buffalo Pumps is classified as a Tier 2 — Litigated product for purposes of legal claims documentation. There is no established asbestos bankruptcy trust fund associated specifically with Buffalo Pumps. Claims involving this equipment proceed through the civil litigation system rather than through a structured trust fund claims process.

Litigation records document that plaintiffs alleging asbestos-related disease connected to Buffalo industrial process pumps have pursued product liability claims in state and federal courts. These claims have typically been brought by individuals diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer who allege occupational exposure to asbestos through work with or around Buffalo process pumps during their industrial careers.

Plaintiffs alleged in these cases that manufacturers and distributors of asbestos-containing pump components knew or should have known of the health hazards associated with asbestos fiber inhalation and failed to adequately warn workers or provide appropriate protective guidance.

Individuals who believe they may have been exposed to asbestos through work with Buffalo process pumps — or family members of workers who have been diagnosed with asbestos-related disease — should consult with an attorney experienced in asbestos litigation. Documentation that may be relevant to a legal claim includes employment records, union membership records, facility work histories, and any available records of the specific equipment present at worksites during the claimant’s period of employment.

Because statutes of limitations apply to asbestos claims and vary by jurisdiction and diagnosis type, individuals considering legal action are encouraged to seek legal consultation promptly following a relevant diagnosis.
