Was Wilden Pump — Air-Operated Diaphragm Pumps and Alleged asbestos documented in litigation?

Wilden Pump — Air-Operated Diaphragm Pumps and Alleged is documented in public asbestos litigation records as a manufacturer whose products contained asbestos during the mid-twentieth century. Workers in industrial facilities, power plants, refineries, shipyards, and commercial construction who handled or worked near these products may have experienced occupational exposure.

Which trades had the most exposure?

Pipe coverers and insulators, pipefitters, boilermakers, millwrights, and maintenance workers are among the trades most frequently documented in asbestos exposure claims. Workers who cut, fitted, or removed asbestos-containing products — and those working in close proximity during that work — typically had the highest fiber concentrations.

How long do workers have to file an asbestos claim?

Statutes of limitations for asbestos personal injury claims vary by state, typically ranging from one to five years from the date of an asbestos-related diagnosis. The clock generally starts at diagnosis, not exposure — mesothelioma can have a latency period of 20 to 50 years. An asbestos attorney can identify the deadlines that apply to your specific situation.

Yes. Workers diagnosed with mesothelioma, asbestos-related lung cancer, or asbestosis after exposure to Wilden Pump — Air-Operated Diaphragm Pumps and Alleged products may pursue claims through civil litigation.

Can family members file secondary exposure claims?

Spouses, children, and household members who developed asbestos-related disease through contact with contaminated work clothing brought home by an exposed worker may be eligible for secondary (household) exposure claims. Wrongful-death claims can also be filed by surviving family members of workers who died from asbestos-related disease.

Overview Product Facts Trades

Litigation Record: Information below reflects allegations in publicly filed asbestos litigation — plaintiff allegations, not findings of fact.

Product Description

Wilden Pump & Engineering, founded by Jim Wilden and headquartered in Grand Terrace, California, was one of the original manufacturers of air-operated double-diaphragm (AODD) pump technology. Wilden AODD pumps were installed at chemical plants, refineries, paint and coatings operations, mining sites, food processing facilities, and municipal wastewater treatment plants across the United States. Wilden pumps handled corrosive acids, solvents, slurries, adhesives, and abrasive fluids.

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Wilden AODD pumps used during the asbestos era contained asbestos-based flange gaskets between the pump body halves, at inlet/outlet manifolds, and at the air-valve assembly interface. Replacement gasket kits and sheet-gasket stock used to rebuild Wilden pumps allegedly incorporated chrysotile asbestos supplied by Garlock, John Crane, and Anchor Packing.

Workers Exposed

Plaintiffs alleged that workers exposed to asbestos through Wilden AODD pumps included:

Chemical-plant and refinery millwrights who broke down Wilden pumps for diaphragm and gasket replacement
Pipefitters and maintenance mechanics who cut and scraped asbestos flange gaskets during pump rebuilds
Paint-plant operators servicing Wilden transfer pumps handling pigments, resins, and solvents
Wastewater and mining maintenance workers rebuilding AODD pumps handling abrasive slurries
