INSTALLATION
INSTALLATION --- SECTION B
Review all SAFETY information in Section A.
Pumps and related equipment must be in-
stalled and operated according to all na-
tional, local and industry standards.
Since pump installations are seldom identical, this
section is intended only to summarize general rec-
ommendations and practices required to inspect,
position, and arrange the pump and piping. If there
are any questions concerning your specific instal-
lation, contact your Gorman-Rupp distributor or
the Gorman-Rupp Company.
Most of the information applies to a flooded suction
installation where liquid is supplied under pres-
sure.
If the pump is positioned above the liquid in a static
lift installation, information such as mounting, pip-
ing configuration and priming must be tailored to
specific conditions.
These pumps are not recommended for
use with water. Some models may be used
with water when fitted with specific options;
consult the factory.
