INSTALLATION (cont.)
Step Seven
3. Flange (LU77 Series): If installing on a flange, select a flange with a thread that is above the plane of
the flange, such as the LM52‐1850.
a. The LU74 & LU78 series works well with Flange installations.
b. Avoid the use of blind flanges with tapped threads or flanges where the threads are even with
the plane of the flange, such as the Banjo 1" Poly ANSI Flange (series AF100).
c. Use a flange with a 2” thread and add a 2” to 1” reducer bushing to complete the installation.
2” Flange w/
thread out of plane
2” Flange w/
thread in plane
2” Flange w/
Reducer Bushing
Do not use thread in plane
4. Side Mount Bracket: For installations in open tanks and sumps, use the LM50 series side mount
bracket.
a. For the LU77 series, order the LM50‐1001‐1, which includes a 2” thread x 1” thread reducer
bushing.
b. For the LU74 & LU78, Series, order the LM50‐1001 side mount bracket.
