specified limit values must under no circumstances be exceeded.   

2.9 Safety of the system in the event of a failure in the dosing system   

DMB dosing pumps are designed according to the latest technologies and are carefully manufactured and tested. However, a failure 

may occur in the dosing system. Systems in which dosing pumps are installed must be designed in such a way that the safety of the 

entire system is still ensured following a failure of the dosing pump. Provide the relevant monitoring and control functions for this.   

 

3. Transport   

3.1 Delivery   

The DMB dosing pump is delivered in a cardboard box. Place the pump in the packaging during transport and intermediate 

storage.   

3.2 Unpacking   

Retain the packaging for future storage or return, or dispose of the packaging in accordance with local regulations.   

3.3 Return   

Return the pump in its original packaging or equivalent. The pump must be thoroughly cleaned before it is returned or stored. It is 

essential that there are no traces of toxic or hazardous media remaining on the pump. 

Grundfos Alldos accepts no liability for damage caused by incorrect transportation or missing or unsuitable 

packaging of the pump!   

Before returning the pump to Grundfos Alldos for service, the 

safety declaration

 at the end of these instructions must be filled in by 

authorised personnel and attached to the pump in a visible position. 

If a pump has been used for a medium which is injurious to health or toxic, the pump will be classified as 

contaminated.

   

If Grundfos Alldos is requested to service the pump, it must be ensured that the pump is free from substances that can be injurious to 

health or toxic. If the pump has been used for such substances, the pump must be cleaned before it is returned.   

If proper cleaning is not possible, all relevant information about the chemical must be provided. If the above is not fulfilled, 

Grundfos Alldos can refuse to accept the pump for service. Possible costs of returning the pump are paid by the customer.   

The safety declaration can be found at the end of these instructions. 

The replacement of the power supply cable must be carried out by an authorised Grundfos Alldos service 

workshop.
