GASKET KIT INSTALLATION
Step 1
Gently remove the adhesive covering from the back of the
PTFE tape. Ensure that the adhesive strip remains attached
to the PTFE tape.
Step 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 in place
during assembly. Do not stretch the tape during placement
in the center of diaphragm bead groove.
Step 3
The end of the tape should overlap approximately 13 mm
(1/2"). Proceed to install the PTFE tape on the remaining
diaphragm.
The Wilden T4 cast iron pumps require PTFE gasket tape
on the liquid chambers (P/N 04-9502-99). Other pump types
may use PTFE gasket kits for additional sealing character-
istics.
During reassembly follow the procedures listed in your
pump’s Engineering, Operation and Maintenance manual.
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.
Always wear safety glasses when performing maintenance
on any Wilden product.
