Dry Vacuum Pumps
Kalbro's oil-less rotary vane vacuum pumps are unlike any other vane pumps on the market. Unlike regular vane pumps, these can be adjusted to account for changes in temperature and operate without any oil.
These vacuums pumps are very robust and require little maintenance due to their single shaft direct drive. That makes them perfect for long-life use with low operation costs. Oil-less rotary vane vacuum pumps are positive displacement devices that feature sliding vanes in a rotating housing and the pumping action of these vanes creates the evacuated volume or a partial vacuum.
Rotary-vane pumps never experience metal-to-metal contact, so they can compensate for wear without having to be repaired. This means they have less maintenance and will stay at peak performance for longer.
Kalbro’s oil-less rotary vane vacuum pumps are an excellent choice for medium or variable vacuum range applications. Watch the video below to learn more about how our oil-less rotary vane vacuum pumps work.
