Dairymaster ACR plunger guide The Dairymaster ACR plunger guide is an essential mechanical component within the Automatic Cluster Removal (ACR) system. It functions to accurately guide the movement of the plunger inside the ram assembly, ensuring smooth and precise operation. By stabilizing the plunger’s motion, the guide helps maintain consistent vacuum regulation and timing for the automatic attachment and removal of milking clusters. This improves milking efficiency and enhances animal comfort by preventing jerky or delayed cluster release. Made from durable materials designed to withstand repetitive movement and dairy farm conditions, the plunger guide requires regular inspection to ensure optimal system performance. Using genuine Dairymaster parts guarantees compatibility and longevity. CR346
