Product Description

SOGEVAC NEO 16/25 D – SKU – 970202V – NEO D25

NEO D pumps are a type of double-stage oil-sealed rotary vane pumps. These pumps inject oil into the pump chamber to ensure that they are sealed, lubricated, and cooled before being recycled from the reservoir and filtered. The lubricating mechanism allows for continuous operation, even at high intake pressures of up to 1000 mbar abs., which makes the NEO D pumps capable of pumping from the atmosphere to the ultimate pressure. The oil the process gas carries is roughly separated in the oil box before further separating in the integrated exhaust filters. These filters catch the fine oil mist and ensure the working environment is 1000 times cleaner than competing pumps lacking this technology. This is achieved by lowering exhaust emissions and eliminating oil mist (≤1 ppm).
