2.5 NPSH CONSIDERATIONS
The HPD liquid end is far superior to conventional
diaphragm liquid ends for suction lift and many
other NPSH critical applications. It’s patented
diaphragm and advanced design rell mechanism
give this liquid end truly high performance in these
applications.
For more NPSH information, refer to Milton Roy
web site (www.miltonroy.com) for aid in evaluating
applications for this liquid end.
SECTION 2 - INSTALLATION
2.6 TYPICAL PIPING
In order to adjust the HPD relief valve, it is
necessary to have a pressure gauge and a
shut OFF valve installed in the discharge line.
The pressure gauge must have a higher range than
the desired pump relief pressure, and should be
installed as close to the pump discharge connection
as possible. The shut OFF valve should be installed
downstream of the pressure gauge. These items
are not required for normal operation, but for
ease of pump maintenance and adjustment, it is
suggested that they be permanently piped into
the line.
Also see the instructions in the appropriate pump
instruction manual for additional typical piping
instructions.
