Abstract
A scroll pump isolates vibrations of a pump head/motor assembly of the pump from the exterior of the pump and thus, suppresses the production of airborne noise. The pump includes a sound-muffling enclosure surrounding the pump head/motor assembly, feet supporting the enclosure, and elastic vibration isolators. The pump head/motor assembly is fixed to the tops of the vibration isolators, and the sound-muffling enclosure is fixed to the vibration isolators at the bottoms of the isolators. The scroll pump also has a locking system by which motion of the pump head/motor assembly relative to the sound-muffling enclosure can be limited or prevented, and by which the sound-muffling enclosure can be hard-mounted to a support surface independently of the feet.
