Energy-Conserving Vacuum Pump

Vacuum Pumps Installing a Variable Speed Drive (VSD), Energy-Conserving Vacuum Pump sometimes called a variable frequency drive, usually saves between 50 and 65% in electrical power costs with the same or better regulation of vacuum. The number of energy savings could be from 30 to 80 percent. They can be adapted to blower or in some instances rotary vane type vacuum pumps. They work by changing the swiftness of the vacuum pump based on the reading from a pressure sensor that is installed on the vacuum line close to the receiver jar. The VSD is basically a dedicated computer with many adjustments so it may be possible to improve vacuum regulation over the typical pneumatic vacuum regulator that just has a vacuum level adjustment. A VSD for vacuum pressure pump is usually economical for a dairy that milks a complete of 8 hours or more per day. Typically a VSD will not be an economical option for little dairies due to less milking period and therefore shorter vacuum pump run times but there are some other choices to save energy costs.
