Important for performance and udder health, a constant milking vacuum is much more than a mere calculation of pump capacity and milk line diameter! 

At WestfaliaSurge we are careful to specify installations with a vacuum capacity that complies with the interntational standard DIN ISO 5707, which provides recommendations for air flow based on the number of milking clusters used in the installation.     

WestfaliaSurge vacuum technology is the prerequisite for gentle, animal-friendly milking: low vacuum means less stress for teats which is a great benefit for udder health. 

The second prerequisite for successful milking is sufficient vacuum capacity: many years of experience have lead to a parlour layout that matches pump capacity to certain pipeline diameters with the goal of achieving a constant vacuum in all parts of the milking installation. This is particularly important in the area between the clawpiece and milk line. 

The third factor is stability: an efficient vacuum controller will respond quickly to sudden and unpredictable vacuum swings due to unexpected entry of air into the system. 

For example:
When attaching the cluster there can be 500 to 600 litres of air sucked into the system through the teat cups. In a WestfaliaSurge installation the capacity of the pump and the sensitivity of the controller ensures that milking is not negatively affected even when more than one operator attaches clusters at the same time. The operating vacuum fluctuates no more than 2kPa. This is quality design!
