Automatic Cluster Flush Systems from Cotswold 

​​​​​​​​​​​Cluster flushing is a very effective way of controlling the transfer of contagious mastitis organisms from cow to cow, during milking. It can also have some effect on environmental mastitis organisms, however, if environmental organisms are the problem, cluster flushing may not always be the answer.


The best way to determine the type of problem is to have samples tested. At CollinsAgri we can arrange for samples to be tested by a specialist veterinary laboratory, if required, just contact us for further assistance.

The Cotswold Automatic Cluster Flush system is a very effective way of sanitizing the milking units between cows therefore, minimising the transfer of contagious mastitis organisms, with a clean cluster on every cow.


The process is fully automatic, with individual unit flushing being initiated by the cluster remover on swingover herringbone and most other parlours. Whole side flushing is activated by the vacuum gate controls, on doubled up herringbone parlours. Doubled up herringbones can alternatively be operated by a separate push button (one per side) if required.

Once activated by the vacuum signal, the cluster flush control module completes the cycle of two flushes, (water and peracetic acid 0.5%) leaving the cluster ready to put on the next cow. Also available is a compressed air operated automatic cluster drop valve, enabling the ACR ram to lower the cluster when flushing, thus aiding drainage.


The Automatic Cluster Flush system has been designed with a unique liquid/pressure cylinder, ensuring only compressed air travels through the solenoid valves, which reduces requirements for solenoid valve replacements and therefore providing our customers with a more reliable and cost effective solution.
