Dismantling/installation
Before dismantling/installation, make sure that the “Shutdown” section is taken into consideration!
WARNING
Risk of burns!
Incorrect dismantling/installation can lead to injuries and damage to property.
Depending on the operating status of the pump and system (temperature of the fluid), the entire pump can get hot.
Risk of burns if the pump is touched!
- Allow the system and pump to cool to room temperature!
WARNING
Risk of scalding!
The fluid is under high pressure and can be hot.
There is a risk of scalding due to escaping hot fluid!
- Close shut-off devices on both sides of the pump!
- Allow the system and pump to cool to room temperature!
- Drain the shut-off branch of the system!
- If no shut-off devices are fitted, drain the system!
- Follow the manufacturer’s instructions and safety data sheets for possible additives in the system!
WARNING
Danger of injury!
Danger of injury caused by falling motor/pump after loosening the fastening screws.
- Comply with national regulations for accident prevention and also with the operator’s internal work, company and safety regulations. If necessary, wear protective clothing and equipment!
DANGER
Risk of fatal injury!
The permanent magnet rotor inside the pump can be a danger to life for people with medical implants during dismantling.
- Removal of rotor from the motor housing is permissible only for authorised and qualified personnel!
- If the unit consisting of impeller, bearing plate and rotor is pulled out of the motor, persons with medical aids, such as cardiac pacemakers, insulin pumps, hearing aids, implants or similar are at risk. Death, severe injury and damage to property may be the result. For such persons, a professional medical assessment is always necessary!
- There is a crushing hazard! When removing the rotor from the motor, it can be pulled back into its original position by the strong magnetic field!
- If the rotor is outside the motor, magnetic objects may be attracted very suddenly. This may cause bodily injury and material damage!
- Electronic devices can be impaired or damaged by the strong magnetic field of the rotor!
In assembled condition, the rotor’s magnetic field is guided in the motor’s iron core. However, there is no magnetic field outside the machine that is harmful to health or affects the machine.
