The cooling fan is mounted on the motor shaft of the Espa Silen or Silen S pump and during operation provides forced cooling of the electric motor by circulating air. A damaged or broken fan causes the motor to overheat, which leads to thermal protection cut-outs and repeated pump failures.
Replacing the cooling fan is a simple service task that significantly extends the lifespan of the entire pump and prevents its permanent failure. The original design guarantees the correct aerodynamic properties and trouble-free fit onto the motor shaft. A suitable replacement for preventive maintenance during regular pump servicing.
