SCR Pump and Dosing Unit

With the aid of ammonia or urea, Selective Catalytic Reduction (SCR) converts nitrogen oxides, also referred to as NOx, into N2 and H2O. Diesel Exhaust Fluid – a solution with 32.5% urea and 67.5% de-ionized water is sprayed into SCR system through a dosing unit and an injector. Efficient application of SCR technology requires a specifically adapted dosing system.
