Edwards nES single EX series rotary vane pumps have been specifically designed to be capable of handling gases from a potentially explosive atmosphere and to operate in environments where a potentially explosive atmosphere can be present. Pumps have been certified under the ATEX directive 2014/34/EU.
DRIVE TECHNOLOGY
Motors are highly efficient meeting latest efficiency standard and are in accordance with UL and European standards.
Motors are certified to ATEX directive 2014/34/EU.
EFFICIENT COOLING
Enables low operating temperatures and increased oil life improving reliability.
OIL RETURN SYSTEM
The optimised oil return and separation system supports stable pumping performance and minimises oil loss. Use of Edwards Ultragrade oil enables optimum pumping performance, and effective time between service.
INTERNAL MECHANISM
Designed to provide optimum pumping performance without fluctuation in vacuum levels.
GAS BALLAST FACILITY
The gas ballast mechanism facilitates
effective pumping and management
of condensable vapours.
INSTALLATION FLEXIBILITY
Pumps are compatible with both ISO and G connections, providing flexibility in installation.
