Urea pump is an important part of the urea solution injection metering system, its main function is to extract the urea solution in the urea tank, and maintain a certain pressure, and then transported to the injection unit to meet the flow and pressure requirements of the injection metering system.
Selective catalytic reduction (SCR) technology is one of the NOX catalytic purification technologies for diesel engines to meet the strict emission regulations in the future, and has the advantages of good safety, low fuel consumption and good sulfur resistance. Its working principle is to use urea solution and NOX REDOX reaction to generate N2, which is non-toxic to the human body, and put it into the atmosphere. The urea pump is to pump the urea solution from the urea tank and transport the urea solution to the nozzle through the delivery pipe
