Oil Diffusion Pumps

SOGEVAC Series

Summarize
Oil sealed rotary vane vacuum pumps are being used in all areas of vacuum engineering. They are equally suited for both industrial production and research applications. They may be used to gene rate a rough and medium vacuum or as backing pumps in pump combinations with Roots pumps or high vacuum pumps. By design, rotary vane pumps run quietly and do not produce much noise.
Many years of experience in vacuum engineering and the latest developments in pump technology combine in the SOGEVAC range the capability to adapt to the requirements of both the industry and the environment. The comprehensive range (pumping speeds ranging from 16 to 1200 m3 x h-1 (9.4 to 707 cfm)) allows every customer to select the right pump for his particular needs. With the new range of compact pumps are from 10 to 100 m3 x h-1 1 these characteristics.

Design Principle
SOGEVAC pumps are oil sealed rotary vane pumps. Oil injected into the pump chamber for sealing, lubrication and cooling of the pump is recycled from the pump’s oil reservoir and filte red before it is injected. The lubricant system is rated for continuous operation at high intake pressures so that the pumps may be used in a versatile manner in most rough vacuum applications (accessories are required for some pumps). The oil carried with the process gas is roughly separated in the oil box before the discharged gas enters the integrated exhaust filters where the fine oil mist is trapped. The thus filtered oil is collected in the oil box and then supplied back to the pump. This demister system, optimized to suit all operating conditions of the vacuum pump ensures oilmist free exhaust gas (degree of separation over 99.9%) even at high intake pressures and when pumping vapors. LEYBOLD rotary vane pumps from the SOGEVAC series excel through numerous special features:

Compact Design
The pumps have been so designed that efficiency of the pumps will be high.

Quiet Operation
SOGEVAC pumps are designed throughout to keep the noise level as low as possible. This is ensured by optimized running and sliding speeds and the selection of low-noise drive motors, as well as perfected manufacturing techniques using CNC automatic machines for optimized tolerances and reproducibility of the individual components.

Protection of the Environment
The built-in exhaust filter ensures an oil-mist free exhaust gas over the entire range of operating pressures – from atmospheric pressure to ultimate pressure.

Supplied Equipment
All pumps are delivered with the required quantity of oil: SV 10 B to SV 65 (B) in a separate canister, whereas the SV 100 (B) to SV 1200 already contain the oil and are thus ready for operation
