Dairymaster Centrifugal Milk Pump Non Return (Complete Assembly) The Dairymaster Centrifugal Milk Pump Non Return (Complete Assembly) is a fully assembled non-return valve unit designed to fit centrifugal milk pumps used in Dairymaster parlour systems. This critical component prevents milk from flowing back toward the pump once it has been discharged, helping maintain consistent flow, reduce noise, and protect both the pump and downstream equipment. Supplied as a complete assembly , this non-return unit includes both the auto drain and air purge features. The auto drain ensures that residual milk is cleared from the non-return chamber after milking, reducing the risk of milk stagnation, bacterial build-up, and blockages. The air purge function helps remove trapped air from the system, supporting smoother flow and stable vacuum conditions during operation. The Dairymaster Centrifugal Milk Pump Non Return (Complete Assembly) is suitable for most, if not all, Dairymaster milk pumps , but due to the variety of models and configurations, it’s important to verify compatibility before ordering.
