# Driving Clean Performance: Gear Pumps for Next-Generation SCR Systems

Reliable urea dosing solutions for demanding on-road and off-road applications.

Precise UREA dosing in SCR systems places high demands on pumps: they must be chemically resistant, deliver stable pressures of up to around 9 bar, and operate reliably even under vibration, temperature changes, and freeze cycles. Gear pumps offer a compact and robust solution for this, as they enable consistent flow rates with minimal pressure fluctuations. The decisive factors here are suitable materials that can withstand urea and ammonia exposure, as well as design measures to ensure wear and freeze pressure resistance.

Precise manufacturing, automated quality testing, and careful material selection enable the production of pumps that guarantee a long service life, low maintenance requirements, and reproducible performance across large quantities. Flexible integration options—from splash-proof areas to in-tank systems—and scalability across international production sites are also relevant for developers and purchasers.

The technologies described also open up potential applications in areas such as water injection, exhaust gas purification in stationary plants, and maritime emission systems.
