E2S
E2S dwustopniowe pompy rotacyjne
Modern industrial two-stage oil sealed rotary vane pump
E2S range: E2S45, E2S65 and E2S85 - perfectly balances performance, cost and usability. A reliable piece of engineering, simply made, well suited for many standard applications that require medium vacuum. It pumps down fast, it handles vapours and it contributes to minimising noise level in your workplace
PECIALISED PERFORMANCE
High pumping speed to reduce cycle times and gain productivity
Hydro mode with improved vapour handling capability to fit with humid applications
Low noise level matching with lab environment expectations
MODERN DESIGN MADE SIMPLE
Economical product with clean layout
Built-in oil filter to protect pump mechanism from contaminants and prevent oil leaks
Innovative design to increase cooling performance keeping high vapour tolerance
No complex mechanical arrangement to keep technology simple
GREAT USABILITY
Effective product design to accommodate users needs
Easy and pleasant to use and service. Cleaning on site to maximise uptime
Efficient over-temperature protection and low oil level detection (optional features)
Increased safety against operator misuse
E2S with EH booster combination
Standard combinations of E2S two stage rotary pumps and EH mechanical boosters are available for high-capacity demands. Factory pre-assembled, these pumping systems are compact, mobile and easy to use. With a direct start from atmospheric pressure our E2S85-EH1200 stack provides 900 m3/h (@60Hz) effective speed and allows to reach high vacuum range with an ultimate vacuum of 2x10-4 mbar.
Applications
- Vacuum degassing and drying
- Heat treatments and vacuum ovens
- Vacuum insulation
- Plasma treatments (except O2 plasma)
- Leak testing
- Gas production and handling
- Research and development
- Backing of high vacuum pumps or systems
