Specific equipment: HP valve
(C2 Series)
The C2 pumps are equipped with HP and LP elastomer valves (FPM™ according to
standard NFT 40-002). In certain applications with fluorinated gases, HP valve may
harden and become brittle and compromise pump performances. Alternatively, the
pump may be equipped with a plastic, corrosion-resistant HP valve on request. On
request we can supply these specific components depending on your needs.

* If a plastic valve is used, the pump’s anti-suckback operation cannot be
guaranteed and an anti-suckback device must be installed in the pumping
line to ensure tightness when the pump is not operating.
