Vacuum Pumps The installation of a Variable Acceleration Drive (VSD), sometimes called a adjustable frequency drive, usually saves between 50 and 65% in electricity costs with the same or better Energy-Conserving Vacuum Pump regulation of vacuum. The range of energy savings can be from 30 to 80 percent. They may be adapted to blower or in some instances rotary vane type vacuum pumps. They work by changing the velocity of the vacuum pump predicated on the reading from a pressure sensor that is mounted on the vacuum collection near the receiver jar. The VSD is actually a dedicated computer with many adjustments so it may be possible to improve vacuum regulation over the normal pneumatic vacuum regulator that just includes a vacuum level adjustment. A VSD for a vacuum pump is usually cost-effective for a dairy that milks a complete of 8 hours or even more per day. Typically a VSD will not be a cost-effective option for small dairies because of less milking period and thus shorter vacuum pump operate times but there are several other options to save lots of energy costs.
