Rocking Piston Pump or Compressor
The rocking piston pump is an oil-free compressor or vacuum pump that is a compact and reliable source of high pressure (to 115 psig) or vacuum (to 29.1 "Hg) at moderate flows of 0.035 to 6.3 CFM. They are available for use on AC or brushless DC power, and as standard or special designs. These pumps are very efficient compared to other types of pumps, such as a diaphragm pump. They are frequently used in medical and dental applications such as autoclaves, sterilizers, dental vacuums, oxygen concentrators, blood analysers, gas analyzers, dryers, water aspirators, electron microscopes, spectrometers, pneumatic beds,nebulizers and blood pressure instrumentation.
