VR series mini-vacuum pumps have no moving parts. They are powered by compressed air and achieve a 26 in.-Hg vacuum with only 0.74 to 1.27 scfm air flow, depending upon size. Providing millisecond attach and release, pump, suspension, and suction cup are one unit and can be positioned close to the load to minimize potential for vacuum loss through tubing. They are constructed of aluminum and brass, and require only 72 psi supply pressure.
