VI.3.4 – Replacing the PTFE sleeves

Follow the same procedure as for VI.3.3 and VI.3.4 until 14); after replacing the composite rings,

remove the PTFE sleeves (P/N 7220) from the groove with a blunt pointed instrument. Clean and re-

assemble the new part.

NB: PTFE sleeves are only compatible with pumps of series 3. A pump that was not originally fitted

with PTFE sleeves can be equipped with sleeves. In this case, you need to change the plates

(P/N 2741 and 2746).

After removing the bellows (see V1.3.2, step 8), remove the bellow Viton O.rings (P/N 2724) and the

body O.rings (P/N 2738 or 2588). Then carefully replace the new ones without scratching the

surface of the bellow (P/N 2760 or 2760S) or housing (P/N 2748 or 2748G).

VI.3.6 – Replacing the manifold O.rings

Follow point VI.3.2 steps 3) and 4). Carefully replace the manifold O.rings (P/N 2464). Take care as

these parts are fragile, especially the elbow connectors.

If your pump is marked with "W", change the manifold seals (P/N 2587) and retighten progressively

with a strap wrench.

NB: This chapter does not concern PFD/S2…G pumps that have no manifold seals.

When dismantling the pump or control unit for service, components found damaged should

be replaced. Alternatively, the pump/control unit can be returned to your distributor or SGPPL

ASTI for examination, estimate, and repair.

A receipt note "Conditions of use" is at your disposal. Do not hesitate to ask for it when needed.

from date of its acceptance.
