MECHANICAL RISKS
1. Mechanical parts subject to wear
The blades
The bearing
The rotor
These parts should be replaced with original spare parts by qualified personal only or in authorized service
centres.
2. Risks due to extreme temperatures
Remember that a very low temperature can freeze the Diesel inside the pump. This situation can cause
serious damage to the motor pump unit.

may cause the plastic parts in the unit to expand. The unit should
thus be placed in a well-ventilated place and protected from the sun.
