This circulates the cooling liquid in the system and is controlled, in the majority of cases, by the motor by means of the belt.
The 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.
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.
