Five Stage Design

The DIJ five stage design incorporates four diffusion stage along with an additional ejector stage which gives the Leybold DIJ Diffusion Pump a higher suction pump speed. This 5 stage design results in quicker pump down to base pressure. Vacuum stable throughput at pressures 10-3 mbar.

Innovative Heater Cartridge Design

In-oil cartridge heater design with a large heating surface that optimizes energy transfer into the oil. Similarly, monitoring of the oil temperature ensures the heaters are not subject to an overheat condition. This constant monitoring also ensures longer element life. In addition, flanged heaters make change-out the fastest in its class.

Unique Baffle Design

Cold cap design is provided at the inlet to minimize oil back streaming into the vacuum chamber. The fore-line baffle is also designed to reduce oil losses for more economical operation.

Electrical Connection Models

Three different variations for each individual application.
1. Basic – simplified OEM connection with male plug
2. Standard – with circuit breaker box
3. ECO version with switchbox and energy control unit

How the  DIJ Diffusion Pumps Meets Your Vacuum Pumping Challenges

Lower Running Costs

During active pump down, power is supplied at 100% but is dropped down as low as 30% during process to reduce energy consumption

Change Oil Only When Really Needed

The ECO Controller monitors oil health to get away from changing oil due to run hours only
