the adhesive strip remains attached to the
Teflon
® tape.
Step 2. Figure 2
Starting at any point, place the Teflon ®
tape in the center of the diaphragm bead
groove on the liquid chamber and press
lightly on the tape to ensure that the adhe-
sive holds it in place during assembly. Do
not stretch the tape during placement in
center of diaphragm bead groove.
Step 3. Figure 3
The ends of the tape should overlap
approximately 1.27 cm (
1 ⁄
2
”) (Figure 3).
Proceed to install the Teflon ® tape on the
remaining liquid chamber.
Only Teflon ® -fitted T8 PVDF and polypropylene pumps come stan-
dard with expanded Teflon ® Gasket Kits (P/N 08-9501-99 for
PVDF and 08-9500-99 for polypropylene). Carefully prepare seal-
ing surfaces by removing all debris and foreign matter from
diaphragm bead and all mating surfaces. If necessary, smooth or
deburr all sealing surfaces. Mating surfaces must be properly
aligned in order to ensure positive sealing characteristics.
