Pump Module BS4
This BS4-compliant pump ensures consistent dosing by maintaining stable pressure and flow of AdBlue/urea to the dosing injector. Built with durable internal components, corrosion-resistant materials, and precision control valves, it performs reliably under varying temperatures and engine load conditions. Its robust construction prevents crystallization, leakage, and contamination, ensuring accurate flow delivery to support efficient NOx reduction.
By providing a steady supply of urea to the SCR catalyst, the pump module helps reduce emissions, maintain BS4 compliance, and improve vehicle environmental performance. It also enhances system reliability, prevents clogging, and ensures smooth operation of the emission control system in heavy-duty commercial vehicles.
