Product Description

Yeomans Chicago Corporation (YCC) — headquartered in Aurora, Illinois; a distinct company from Chicago Pump Company — manufactured through the twentieth century a specialty line of sewage, wastewater, storm-water, and industrial process pumps widely installed in municipal wastewater-treatment plants, sanitary and storm-water lift stations, industrial effluent handling systems, and general industrial process applications. YCC pumps were engineered for the abrasive, corrosive, and solids-laden service conditions characteristic of municipal and industrial fluid-handling.

Product families included vertical and horizontal non-clog centrifugal sewage pumps, submersible and dry-pit lift-station pumps, grinder pumps, effluent pumps, and industrial process pumps for chemical and paper-mill service.

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that YCC sewage, wastewater, and industrial pumps were furnished through the asbestos era with braided asbestos packing at the shaft stuffing boxes, asbestos compressed-sheet gaskets at the casing splits and volute-cover joints, and asbestos flange gaskets at the suction and discharge piping connections. When municipal and industrial mechanics tore down these pumps for scheduled inspection, wear-ring replacement, or impeller service, they allegedly disturbed the original and successor asbestos gaskets and packing.

Workers Exposed

Municipal wastewater-treatment plant operators, sanitary and storm-water lift-station mechanics, and industrial maintenance workers who serviced Yeomans Chicago Corporation pumps allegedly encountered asbestos-containing materials as routine maintenance. Millwrights and industrial mechanics who pulled the pumps for overhaul separated the casings, scraped old gaskets off the flange faces, and cut and installed new asbestos compressed-sheet gaskets to reassemble the volutes and covers. Pipefitters who broke the suction and discharge piping flanges disturbed the pump-side flange gaskets. Municipal plant operators and lift-station mechanics repacked the stuffing boxes on scheduled intervals, removing dried braided asbestos packing rings and installing new ones. These tasks were repeated across each pump on the plant on a recurring maintenance cycle over careers that could span decades.
