Control variants
 |
 |
| + simplicity + high torque at small packaging + low cost - 50 % fail-safe |
+ 100% fail-safe i.e. engaged at loss of power - electromagnet more expensive - less compact |
 |
 |
| + only electrical pulse required for switching + no continuous power drain (inherent stability) + small size solenoid (pulse operation only) + virtually no heat generation within solenoid - electromagnet more expensive (compared to standard) - no fail-safe operation |
Water pump clutch Optimize thermo management Two-speed water pump clutches reduce fuel consumption and help to optimize thermal management by providing fast switching time and a fail-safe minimum rotation speed. The integration of the clutch within the pulley minimizes packaging. Switched water pumps are state of the art for modern Euro 5/6 engines.
