    STANDARD operating X9 series pumps are not suitable for use in potentially explosive areas ! WARNING: X9 series pumps for hazardous areas must be especially ordered for said use ! In potentially explosive atmospheres must be used only ATEX execution pumps with a flameproof motor ! All pumps in ATEX execution differ from NON ATEX (or standard execution) pumps in that they are fitted with a second identification plate with specific indication of the data required by the directive.

  • Page 12: Prohibited Use

    For a correct use of the pump, the user must comply with the power frequency range allowed by OBL, defined and including from 30Hz to 80Hz. Moreover, IT MUST NOT EXCEED the max operating pressure indicated on the pump nameplate. This value is downgraded and takes into account the maximum operating regime at maximum allowable power frequency (80Hz).
