Component parts: Impeller: supplies the fluid with the necessary energy to cover the entire cooling circuit. Mechanical seal: ensures fluid seal inside the pump. Bearing: transmits movement to the impeller and supports any ventilation parts. Entrainment part: for transmitting movement to the bearing. Pump body: supports the basic pump component parts and conveys the coolant in the motor block.

Product Features:
  • 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.
