Diaphragm Vacuum Pumps
Diaphragm pumps have no lubricant (oil-less), and they use a flexible cavity to move gases within the pump. The chemically resistant diaphragm cylinders (and seals) fluctuate back and forth drawing air into the vacuum.
One of the major advantages of this type of pump is the reduced maintenance costs associated with oil-free operation.
