J. Pressure relief (high pressure):
The pressure relief valve (6) protects the HP
streams in the system against pressure
overload and relieves the water if the pressure
exceeds the maximum set pressure. If the
high-pressure pump is a positive displacement
pump, the pump can built up a very high
pressure that will exceed mechanical strength
of the membrane housing, pipes and other
accessories. When using Danfoss APP pumps
with Danfoss VCM check valves, it is recom-
mended to place a pressure relief valve or
pressure safety valve as illustrated. In case the
Danfoss check valves are not used, the valve
must be placed between pump and check
valve (See 180R9371, Design Guide Pressure
safety valve in seawater RO sytem for more
details).
