Operational reliability
The large, integrated fine-mesh water filter reliably protects the high-pressure pump against dirt particles. An integrated exhaust gas thermostat switches off the drive motor if the exhaust gas temperature exceeds 300°C. The soft damping system (SDS) compensates for vibrations and pressure surges in the high-pressure system.
