Step 1.
Figure 1
Gently remove the adhesive covering
from the back of the PTFE tape. Ensure
that the adhesive strip remains attached
to the PTFE tape and is not removed
with the adhesive covering.
Step 2.
Figure 2
Starting at any point, place the PTFE
tape directly on top of the diaphragm
bead. Press lightly on the tape to ensure
that the adhesive holds it in place during
assembly. Do not stretch the tape during
placement on the diaphragm bead.
Step 3.
Figure 3
The end of the tape should overlap
approximately 13 mm (1/2"). Proceed to
install the PTFE tape on the remaining
diaphragm.
P1 PVDF and Ultrapure pumps come standard with expanded
PTFE Gasket Kits (P/N 01-9501-99) for all sealing surfaces.
P1 Poly pumps come standard with expanded PTFE Gasket
Kits (P/N 01-9500-99) for diaphragm bead only. Carefully
prepare sealing 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.
Step 4.
Figure 4
Carefully remove the protective covering from the back of
the PTFE gasket attached to tape.
Step 5.
Figure 5
Install the valve ball, valve seat and o-ring.
Step 6.
Figure 6
Center the gasket so that it evenly covers the o-ring and seat
areas.
Step 7.
Figure 7
Gently apply pressure to gasket to ensure the adhesive main-
tains a positive seal to stay in place during pump assembly.
