Diaphragm Pumps N 143/186.12 

28 

Translation of original Operating and Installation Instructions, english, KNF 121610-121613 07/16 

11.  Returns 

Pumps and systems used in laboratories and process-based 
industries are exposed to a wide variety of conditions. This means 
that the components contacting pumped media could become 
contaminated by toxic, radioactive, or otherwise hazardous sub-

stances. 

For this reason, customers who send any pumps or systems back 
to KNF must submit a Health and safety clearance and decontami-
nation form in order to avoid a hazardous situation for KNF em-
ployees. This Health and safety clearance and decontamination 

form provides the following information, among other things: 

 

physiological safety 

 

whether medium-contacting parts have been cleaned 

 

whether the equipment has been decontaminated 

 

media that have been pumped or used 

To ensure worker safety, work may not be started on pumps or 
systems without a signed Health and safety clearance and decon-

tamination form.  

For optimal processing of a return, a copy of this declaration 
should be sent in advance via e-mail, regular mail, or fax to KNF 
Customer Service (refer to final page for address). In order to avoid 

endangering employees who open the shipment's packaging, 
despite any residual hazards, the original version of the Health and 
safety clearance and decontamination form must accompany the 

delivery receipt on the outside of the packing. 

The template for the Health and safety clearance and decontami-
nation form is included with these operating instructions and may 

also be downloaded from the KNF website. 

The customer must specify the device type(s) and serial number(s) 
in the Health and safety clearance and decontamination form in 
order to provide for the unambiguous assignment of the Declara-

tion to the device that is sent to KNF. 

In addition to the customer's declaration of physiological safety, 
information about operating conditions and the customer's applica-
tion are also of importance to ensure that the return shipment is 
handled appropriately. Therefore, the Health and safety clearance 

and decontamination form requests this information as well.
