How to choose a vacuum pump
Thread Content
Oil-free vertical vacuum pumps, Roots pumps, water ring jet pumps, screw pumps – what are the differences?
If environmental requirements apply or recycling is possible, choose a dry pump; otherwise, choose a water pump or an oil pump
Select a vacuum pump based on the operating conditions. Screw pumps represent a trend for the future – they are environmentally friendly and clean. When the requirements are not so strict, a water ring pump is also a good choice – it’s inexpensive
They are widely used in water ring pumps, with a low failure rate.
