Sleeve Silicone Milk Pump Success

Sleeve Silicone Milk Pump (Lely A4 Compatible)

Part Number: 5.1004.1761.0 | Item Code: 208045

Suitable for Lely Astronaut A4 Robotic Milking Systems

Maintain the suction integrity and hygienic performance of your milk transport system with the Silicone Milk Pump Sleeve. Specifically engineered for the Lely Astronaut A4, this high-grade silicone sleeve is a critical internal component of the milk pump assembly, ensuring smooth, leak-proof operation during both milking and wash cycles.

In a 24/7 robotic environment, the milk pump sleeve is subjected to constant mechanical flexing and regular exposure to high-temperature CIP (Clean-In-Place) chemicals. Over time, silicone can lose its elasticity or develop microscopic tears, which can lead to air leaks, reduced pumping efficiency, or "dead zones" where bacteria can accumulate. Replacing this sleeve is a vital part of your preventative maintenance schedule to keep your IBC levels low and your milk flowing consistently.

Maintenance Tip

When inspecting your milk pump, look for any signs of "cloudiness" or loss of elasticity in the silicone sleeve. If the sleeve feels gummy or shows visible cracks, it should be replaced immediately. A failing sleeve often manifests as a "noisy" pump or a pump that struggles to prime. For a complete repair, we recommend the Service Kit Complete Milk Pump (5.1004.1546.0)
