Vacuum Pumps Installing a Variable Velocity Drive (VSD), sometimes called a adjustable frequency drive, usually saves between 50 and 65% in electrical power costs with the same or better regulation of vacuum. The range of Energy-Conserving Vacuum Pump china 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’s installed on the vacuum line near the receiver jar. The VSD is actually a dedicated computer with many adjustments so it may be possible to boost vacuum regulation over the normal 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 total of 8 hours or more per day. Typically a VSD will not be an economical option for small dairies due to less milking period and therefore shorter vacuum pump run times but there are some other options to save lots of energy costs.
