Constructed with a highly durable stainless-steel body, these pumps are specifically engineered for continuous operations at constant liquid levels within circulating tanks. Because they utilize a sealless structure, the design significantly reduces common mechanical issues caused by heat generation or friction abrasion, and it remains highly resilient even when handling liquids that contain small amounts of slurry.

In industrial settings, this pump series is primarily utilized in surface treatment and chemical processing applications. It is commonly deployed for desmear and blackening treatments, electroless nickel plating, and within high-temperature industrial washing machines. The webpage also accommodates specific model configurations—including the YD-4001LON3 through YD-5005LON3—and offers downloadable technical assets such as product catalogs, CAD files, and operational videos.
