Leybold DIJ 20 High Vacuum Diffusion Pump - NEW
DIJ benefits at a glance
■ Most innovative heating concept utilizing newly developed heater cartridges with large heat exchange surface for an optimized energy transfer into the oil. Effective temperature monitoring protects the system against overheating. The insulated heater area ensures minimum energy losses.
+ Minimum stress and longest lifetime for heaters and oil
+ Highest uptime
+ Flanged heaters, easy to exchange
■ Choice of flange variants for improved connectivity
+ ANSI / Inch flanges (with O-ring)
+ ISO-F or ISO-K flanges (with centering ring)
■ Unique baffle design + Proven cold cap baffle at the inlet to minimize oil backstreaming
+ Innovative, new foreline baffle for reduced oil losses
■ Various electrical connection opportunities to meet customers requirements
+ Basic – simplified OEM connection with male plug
+ Standard – with circuit breaker box
+ ECO, with switchbox and energy control unit
■ Five stage system design provides excellent performance data

Power Efficiency Control -
Energy savings up to 30% without power loss
Oil diffusion pumps require a certain minimum oil temperature for operation. Commonly, 100% of the installed heating power is constantly utilized. The innovative Leybold power efficiency control unit for diffusion pumps cuts power consumption by up to 30% since the supplied power is significantly reduced after the pump has attained its operating temperature. Further savings result from the utilization of the standby mode at a reduced temperature.
Cost reductions through energy-savings (up to 30%)
- Increased service life of oil and heating cartridges
- Excellent operating convenience and simple use
- Fast ROI (< 2 years)
- Simple, visual monitoring of the parameters
- PLC driven
- USB Interface and Ethernet
