Gasket Kit / Installation
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 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
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
The end of the tape should overlap
approximately 13 mm (1/2"). Proceed to
install the PTFE tape on the remaining
diaphragm.
Step 4
Carefully remove the protective covering from the back of the PTFE
gasket attached to tape.
Step 5
Install the valve ball, valve seat and o-ring.
Step 6
Center the gasket so that it evenly covers the o-ring and
seat areas.
Step 7
Gently apply pressure to gasket to ensure the adhesive maintains a
positive seal to stay in place during pump assembly.
