Vacuum Pumps Installing a Variable Rate Drive (VSD), sometimes called a adjustable frequency drive, usually saves between 50 and 65% in electricity costs with the same or better regulation of vacuum. The number of energy savings can be from 30 to 80 percent. They could be Energy-Conserving Vacuum Pump adapted to blower or in some cases rotary vane type vacuum pumps. They function by changing the velocity of the vacuum pump predicated on the reading from a pressure sensor that is installed on the vacuum series close to the receiver jar. The VSD is actually a dedicated computer with many adjustments therefore it could be possible to boost vacuum regulation over the normal pneumatic vacuum regulator that only has a vacuum level adjustment. A VSD for vacuum pressure pump is usually cost-effective for a dairy that milks a total of 8 hours or even more each day. Typically a VSD will not be a cost-effective option for little dairies due to less milking time and thus shorter vacuum pump operate times but there are some other options to save energy costs.
