These Leybold DIJ High Performance Diffusion Pumps Include the Series DIJ10, DIJ16, DIJ20, DIJ35, DIJ320, DIJ500, DIJ630, and DIJ1000. This model is the DIJ 35 model set up for the Color LED Energy Efficiency Control Unit for up to 30% Energy Savings without power loss. (The EEC is NOT Included with this pump but has a plug allowing the Pump ECC to be added with purchase or at a later time) These pumps are the primary industrial standard for high vacuum pumping mechanisms. The Leybold DIJ diffusion pumps have a high pumping speed for all gases and low cost per unit pumping speed when compared with other types of pump used in the same vacuum range. They have an 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. Having ANSI or ISO Flanges having proven cold cap baffle at the inlet to minimize oil backstreaming and innovative new foreline baffle for reduced oil losses.

This DIJ Diffusion pump has a five stage system design that provides excellent performance data. With Four diffusion pump stages for highest suction speed at low pressures and lowest final pressure. And the last ejector stage for high forevacuum stability and stable throughput at pressures >10-3 mbar.

These Leybold DIJ high vacuum, high throughput diffusion pumps are new and can be ordered with either a 3-phase 400 or 460V heaters and three different versions. The Basic (OEM Connection with Harting Y Plug), Standard (with circuit breaker box) or EEC (with a switch box and LED Energy Efficiency Control Unit). When ordering please specify which voltage your application will require. We stock and sell diffusion pump oils, along with vacuum fittings, adapters, and replacement parts for your Leybold DIJ diffusion pumps. This pump uses Leybonol diffusion pump fluid and is designed for high vacuum and fast pumping of large volumes of gas or vapor in production operations.
