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.
