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. 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". A BouMatic Variable Speed Drive is the way to achieve the correct amount of air-flow for your system.
On-farm trials have produced electrical savings of more than 60%. 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.
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.
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 controller - 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.
