Vacuum pumps

Liquid ring pumps
are particularly suitable for machining withcoolant, as they combine vacuum pump and liquid separator.

Dry-running, vane-type rotating pumps
can be used for wet machining, if a liquid seperator is there. They are very low maintenancebecause they do not require lubrication.

Oil-lubricated, vane-type rotating pumps
provide very high vacuum. The main application of these pumps is the dry cutting.

Side channel blowers
offer very high suction at relatively low pressure. Especially with a lot of leakage and large work surfaces, these pumps are recommended.

Air powered vacuum generators
offer a price advantage if buying. For everyone who works hard and often with a vacuum, it is cheaper to buy a vacuum pump.
