* In August 2003 the NEMA pump code was
discontinued for all material numbers created
by GRUNDFOS manufacturing companies in
North America. The NEMA version pump code will
still remain in effect for existing material numbers.
NEMA version pumps built in North America after
this change will have either an A or U as the pump
version code depending on the date the material
number was created.
P PJE coupling
X Special version
