BBA Pumps has released the Stage IV pump units in the power range 130 – 560kW, fully in accordance with the 2014 European emission regulations for diesel engines in off-road applications.
Pump units driven by engines with SCR (Selective Catalytic Reduction) system use high-efficiency combustion, which results in lower fuel consumption and reducing NOx emissions from 2.0 g/kWh to 0.4 g/kWh – a massive 80%.
How SCR works: Before the exhaust gases pass through the catalytic converter, up to 5% AdBlue® is added. The NOx is then converted to harmless nitrogen gas and water vapour, and released into the environment.
Reduced overall costs: For the end users, the principal benefit of pump units with SCR engines start with unsurpassed fuel efficiency that cuts in operating costs. The catalytic converter is designed to last the life of the engine, costs for maintenance and downtime are also reduced.
