General description
Vacuum supply
The VMS is connected to the vacuum
supply system. In some VMS configurations
up to three milking stations uses the same
vacuum pump. To regulate the maximum
vacuum consumption of each VMS, a flow
regulating valve (FRV) is installed in the
vacuum supply system. This is to ensure a
sufficient vacuum to each VMS.
Pulsators
Alternates the vacuum level in the teatcup
chamber so that the liner opens and closes.
