Vacuum Pumps Installing a Variable Acceleration Drive (VSD), sometimes Energy-Conserving Vacuum Pump 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 could be adapted to blower or in some instances rotary vane type vacuum pumps. They function by changing the rate of the vacuum pump predicated on the reading from a pressure sensor that’s installed on the vacuum collection close to the receiver jar. The VSD is basically a dedicated computer with many adjustments therefore it could be possible to improve 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 complete of 8 hours or more each day. Typically a VSD will never be a cost-effective option for little dairies due to less milking period and therefore shorter vacuum pump run times but there are several other options to save lots of energy costs.
