The engine cooling system has a temperature stabilization function in case of temperature increases exceeding the predicted limits. The coolant is circulated through a water pump that guarantees the correct flow at all engine speeds.

Deficiencies in the system can cause significant damage to the motor. Therefore, regular/systematic checks of the water pump are extremely important.

In many applications, the water pump is controlled by a distributor belt. Therefore, during maintenance of the distributor control system, it is crucial to inspect and, if necessary, replace the water pump.

The key factors that demonstrate the quality of our pumps are as follows:

• The ball bearing supports the drive wheel on one side and the roller on the other. This support must guarantee continuous sliding/travel on the drive line and react to the load generated by the control system. These can be double-wheeled or single-wheeled (rotating side) and a roller wheel (pulley side). The geometric shape of the ball bearing is determined by the vehicle manufacturer according to the load generated by the system.
• The impeller can be made of a synthetic material loaded/filled with glass, steel, or cast iron fibers. The cross-sections of the small vanes are crucial to prevent deformation/hollowing effects and guarantee correct flow. The impeller's construction is extremely complex, as it must consistently guarantee liquid distribution at all engine speeds.
• The retainer/seal is mounted between the rotary bearing and the ball bearing. At all operating temperatures and rotational speeds, this retains the liquid, preventing leakage onto the ball bearings and avoiding irreversible damage to the pump.
• The pump housing is typically made of aluminum or plastic, depending on the vehicle manufacturer's specifications. In either case, the pump housing must have the correct rigidity and ensure the correct system geometry.
