Uses an optimized all metal impeller design to assist in cooling under high RPM, and performance demands.
This water pump is centrifugal in type and comprises a bladed rotor linked by means of a shaft (which rotates on bearings housed in a support) to the drive gear; the seal between the pump and the motor block is guaranteed by a gasket, while the inside of the pump is guaranteed by a mechanical seal.

E9 3.0CSL Coupe, Euro- All the component parts fitted are pre-tested to evaluate durability, performance and reliability.
- The bearings undergo a durability test equivalent to nominal lifespan and are then inspected to assess integrity.
- The mechanical seals are tested in extreme coolant temperature conditions according to predefined cycles.
- The shape of the impellers is optimized thanks to the use of prototypes on which flow and performance tests are performed.
- On both the entrainment parts and the bodies, the choice of materials and/or technologies different to original ones is made on the basis of structural and mechanical tests.
- After assembly all the pumps undergo seal tests on units that reject those with leaks above set limits
