Energy-Conserving Vacuum Pump vacuum Pumps Installing a Variable Velocity Drive (VSD), sometimes called a variable frequency drive, usually saves between 50 and 65% in electricity costs with the same or better regulation of vacuum. The range of energy savings could be from 30 to 80 percent. They can be adapted to blower or in some cases rotary vane type vacuum pumps. They work by changing the quickness of the vacuum pump based on the reading from a pressure sensor that is mounted on the vacuum collection close to the receiver jar. The VSD is basically a dedicated pc with many adjustments so it could be possible to boost vacuum regulation over the typical pneumatic vacuum regulator that only includes a vacuum level adjustment. A VSD for a vacuum pump is usually economical for a dairy that milks a complete of 8 hours or even more per day. Typically a VSD will never be an economical option for small dairies because of less milking period and therefore shorter vacuum pump operate times but there are some other options to save energy costs.
