NEO D
Oil sealed pumps
Triple-hitting vacuum technology for a clean, quiet and long-running performance
Leybold NEO D oil sealed rotary vane pumps excel in industrial and analytical application with their low noise levels, smooth and clean operation. When processes rely on continuous vacuum, reliable, high-performance vacuum technology is essential. NEO D, with less noise and fewer emissions contributes to a better work environment with higher levels of productivity in demanding applications.
NEO D pumps are double stage oil sealed rotary vane pumps. Oil is injected into the pump chamber for sealing, lubrication and cooling of the pump and is recycled from the pump’s oil reservoir and filtered. The lubrication system delivers continuous operation at high intake pressures (max. 1000 mbar abs.) making the NEO D pumps versatile to pump from atmosphere down to ultimate pressure. The oil carried with the process gas is first roughly separated in the oil box and then in the integrated exhaust filters where the fine oil mist is trapped. The separating system lowers the exhaust emission and is free of oil mist (≤1 ppm) delivering a 1000 times cleaner working environment as compared to competitive pumps without this technology.
The NEO D excels also in vapor pumping performance: thanks to its integrated exhaust demister, which is at pump temperature. Thus, there is no condensation in the pump and vapors cross the pump in gas phase. External oil demisters have the disadvantage of being at ambient temperature what favors condensation. Condensed vapors will return then into the pump which may deteriorate their performance and lubrication.
To push the vapor handing performance further, a specific NEO 16 SD version has been developed, with a slightly higher but still comfortable operating temperature, to double its vapor tolerance!

Compact design
Compact design
NEO D pumps have a common shaft for the motor and vacuum generator making the pump compact. With the NEO D pumps, you get 30% more space as compared to competitive pumps.
Quiet operation
Quiet operation
Leybold NEO D oil sealed rotary vane pumps are designed to keep the noise level as low as possible. By using perfected manufacturing techniques, the NEO D is ideal for applications that need low noise and vibrations.
Anti-suckback valve
Anti-suckback valve
The anti- suckback valve (called ASBV) is protected by a metal wire mesh filter. During a pump stop (for example due to shut down or a power failure), the ASBV closes the intake hydraulically & quickly. This prevents the pressure from rising in the connected chamber while the pump is vented at the same time. Any suckback of pump oil into the vacuum system is effectively prevented. This process operates under all operating conditions even when the gas ballast valve is open.
Environment friendly
Environment friendly
The built-in exhaust filter ensures an oil mist-free exhaust over the entire range of operating pressures – from atmospheric pressure to ultimate pressure.
Ready to Use
Ready to Use
All pumps are delivered with the required quantity of oil, already filled in and are thus ready for operation.
