Tandem seal option for the Dean RA Series air-cooled pump helps protect environmentally sensitive areas from ground leaks, increase safety with added protection to avoid flammable fluids and improve compliance with insurance requirements. The pump includes a shaft-mounted fan to move airflow over the cooling fins on the exterior of the pump. This technology eliminates the need for external flush plans to protect the bearings and mechanical seal from overheating. The company incorporated the tandem seal option into the fan design by utilizing an inert barrier fluid between two seal faces whose level and pressure is controlled using Plan 52 technology.
