Description
This unit is a high-capacity turbomolecular pump from Oerlikon Leybold Vacuum, Turbostream series, model D2500G / 877011. Turbostream pumps are widely used in CO₂ laser cutting systems, vacuum coating systems and various high-vacuum research applications, offering high rotational speed, large pumping speed and reliable performance.
The offered D2500G is a used, de-installed pump, originally running on a CO₂ laser cutting machine. It was working before removal and has been stored since. The overall cosmetic condition is good and the oil level indicator shows a normal range (see actual photos). Ideal as a spare or replacement pump for compatible laser cutting or vacuum systems.
