Step 7.
Figure 7
Gently apply pressure to gasket to ensure the adhesive
maintains a positive seal to stay in place during pump
assembly.
Step 6.
Figure 6
Center the gasket so that it evenly covers the o-ring
and seat areas.
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 2.
Figure 2
Starting at any point, place the PTFE
tape in the center of the diaphragm
bead groove on the liquid chamber
and press lightly on the tape to
ensure that the adhesive 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 13 mm (1/2").
Proceed to install the PTFE tape on
the remaining liquid chamber.
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.
Only P4 PVDF pumps come standard with expanded
PTFE Gasket Kits (P/N 04-9501-99). 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.
