What is a VacuumJak®?  
VacuumJak series

It is a variable speed vacuum pump controller with a sensor.

During milking the VacuumJak® system automatically maintains a vacuum level of your choosing. The system changes pump speed each time a milk claw is added or dropped so that steady vacuum is presented to all cows. Pump speed is related to milk, wash, and rinse activity. The system controls pump speed to provide you with a strong vacuum while reducing your electricity costs and increasing pump life.  
What's in your barn?
dairy milking
  On average, the VacuumJak® system can yield an electrical energy savings of $10/Hp/month. A 65 cow herd using a 7.5 Hp pump and a motor saves about $71/month based on 2 hours of milking, 1.5 hours of wash and rinse, 2 milking sessions each day, and an energy cost of 8 cents/KWH.
  If your milk/wash/rinse times are longer due to larger herd or your energy costs are higher, then more money will be saved. The long and the short of it is that you will save about $1.00 per cow each month because you'll use less electricity during milking, wash, and rinse!
Give longer life to your existing equipment and put a few bucks back in your pocket!
