3.5 Intended use
sera diaphragm relief valves are only to be deployed according
to the intended purpose stated in the order confirmation.
sera does not assume any responsibility for damage resulting
from an operation which does not conform with the intended
use.
If the diaphragm relief valve is to be used for other applica-
tions, then the suitability of the valve for the new operating
conditions must be discussed with sera beforehand!
Criteria for proper operation of the diaphragm relief valve:
• Max. operating pressure of the diaphragm relief valve
• Observe characteristics of the pumped medium (please
see safety- and product data sheet of the pumped medi-
um – the safety data sheet is to be provided by the sup-
plier of the chemical)
• Resistance of the materials which come in contact with
the pumped medium
• Operating conditions at the place of installation
• Temperature of the pumped medium
sera does not assume any responsibility if these criteria are
not or only partly observed by the owner / operator.

The structural design of the diaphragm relief valve must
not be changed!

ating personnel must be familiar with all applicable accident
prevention and safety instructions and regulations.
3.7 Personal protection for maintenance and
service
In order to avoid risks to health, the provisions of the German
Ordinance on Hazardous Substances (GefStoffV) (§14 Safety
