Both milking robots that work round the clock, and smaller milking systems have to work reliably and safely. Mink vacuum pumps guarantee a continual vacuum supply that is always available during permanent operation. Mink vacuum pumps work completely oil free. This reduces maintenance expenditure to a minimum and avoids contamination through oil as is otherwise the case with conventional vacuum pumps. Mink claw vacuum pumps are already being used by manufacturers of milking robots all over the world. Retrofitting in milking systems is always possible.
