Variable Speed Control

VARIABLE SPEED DRIVE for Vacuum Pump

Reduce energy use and cut the money spent on electricity with the Variable Speed Drive for vacuum pumps from BouMatic.

Now, dairy producers can significantly cut energy costs by equipping their vacuum pump with a variable speed drive from BouMatic. The variable speed drive can speed up or slow down the vacuum pump to produce just the amount of airflow needed at any point during milking or cleaning. On-farm trials have produced electrical savings of up to 60 percent when using a vacuum pump equipped with a variable speed drive.

Wasted Energy - Constant-speed vacuum pumps turn out much more airflow than is required for milking or for cleaning a milking system. Traditionally, one or more vacuum pumps are used to produce a minimum constant airflow of six-cfm (170 L/min) per milking unit.

More Airflow than Needed is Often Used - Recent scientific research has determined that the amount of air-flow actually used for "steady state" milking - when all milking units are attached without any squawking teat cups or air leaks - is as little as 1 to 2 cfm (30 to 60 L/min) per unit. Even a superb, sanitary cleaning of the milking system requires only 2 to 2.5 cfm (60 to 70 L/min) per milking unit, if the CIP system is properly set and balanced.
Sometimes, Additional Airflow is Needed - There are times during milking when additional airflow is required, such as when attaching units, when there is a squawking liner, or when a milking unit falls off. There are also times during the cleaning of the milking

system when additional airflow is needed, such as when an air injector admits atmospheric air into the milk line to form a "wash slug".

New Standards are introduced - Through research and on-farm tests, the ASAE (American Society of Agricultural Engineers) and the ISO (International Standards Organization) revised their standards to reflect new scientific knowledge. This new knowledge shows it is no longer necessary to run a vacuum pump at a constant speed to produce the maximum amount of airflow needed for only short periods.

Safety - CSA, UL, or CE certified controllers - the proof of safety and quality from around the world.

Features:

  • On-farm trials have produced electrical savings of more than 60%.
  • Quieter operation. A vacuum pump equipped with a BouMatic variable speed drive will frequently operate at one-half the RPMs that it would be running at if it were not equipped with a variable speed drive. When a vacuum pump operates at slower speeds, it is quieter.
  • Two-year warranty - proven technology provides peace of mind.
  • Electronic noise shield is built into the controller so the VSD operation will not interfere with computerized systems' electronic communications.
  • Reduced wear on vacuum pump by lowered RPMs.
  • A system switch provides the option to switch between variable speed and constant speed operation.
  • CSA, UL, or CE certified controllers - the proof of safety and quality from around the world.
  • The BouMatic VSD controller can be installed to operate a second, stand-by vacuum pump.
