Benefits
Resistant to aggressive gases and vapor
Ideal for the chemical and pharmaceutical industries, it reliably handles aggressive gases, corrosive vapors and high volumes of water vapor without damaging the system.
Temperature control without condensation
Precise temperature control prevents condensation, polymerization and media sticking inside the pump, significantly extending its service life.
Modular design for maximum flexibility
The single-stage or two-stage configuration can be adapted to the application, simplifies servicing and allows upgrades to more complex vacuum systems.
Continuous flushing and system protection
A thin film of fresh oil lubricates, seals and flushes aggressive media from the pump, reducing wear and improving operating reliability.
ATEX configuration for hazardous areas
An ATEX-certified configuration is also available for safe use in potentially explosive areas.
