Насос жидкости для очистки дизельных выхлопных газов Caterpillar 6553990

The Diesel Exhaust Fluid (DEF) Pump is a necessary component of the selective catalytic reduction (SCR) system in equipment. It draws DEF from the storage tank and delivers it at an accurate pressure to the dosing unit, where it is sprayed into the exhaust stream. This process converts harmful nitrogen oxides into nitrogen and water vapor, ensuring compliance with stringent emission standards. Equipped with advanced sensors, the pump maintains consistent flow rates and prevents crystallization in the system.Attributes:• Operates within a specific pressure range to ensure accurate DEF dosing in the SCR system.• Function reliably under extreme temperatures, from freezing to high-heat environments.• High-quality seals are used to maintain system integrity and prevent fluid leaks.Applications: The Diesel Exhaust Fluid Pump is installed near the DEF storage tank in equipment integral to the SCR system, enabling accurate delivery of DEF to the exhaust stream for emission control.
