This type of vane oil pump is intended especially for the packaging industry, where it must work in a cyclical mode. Ie. up to 8.5 min. running, 1.5 minutes stopped, so that the oil collected in the separator can drain back into the oil circuit. It has a simple design with a single shaft and direct drive, which creates a robust device with a long service life and low maintenance and operating costs. The vanes are displaced by an oil film.

They are characterized by the following properties:

• small dimensions, low weight, easy integration
• limit vacuum 2 mbar (a)
• oil-filled vacuum pumps were developed specifically for the requirements of tabletop packaging machines
• ideal for vacuum packaging of food (meat, fish, meat products, cheeses ...)
• The O 6.8 vacuum pump is a very robust solution for various requirements in industry
• wide range of accessories (suction filters, liquid separators, gas-ballast valves, etc.)

The maximum suction quantity is specified at an atmospheric pressure of 1000 mbar abs., a temperature of 20°C and a frequency of 50Hz.
