Corrosive applications:
C2 Series
(1)
Partial ultimate pressure measured according to Pneurop 6602 specifications with A113 oil
charge. It may vary if other oils are used (see page 17).
(2)
These values are for pumps equipped with IE2 European three-phase motors.
Note: The pressure measurements were made with a capacitive diaphragm pressure gauge
measuring a total pressure in the absence of a cold trap. Measurements using a Pirani type
gauge can give different pressure values.
