Pulsator Service Kit for Lely

Pulsator Service Kit (Lely Compatible)

Part Number: 5.1004.6255.0

Suitable for Lely Astronaut A4 & A5 Robotic Milking Systems

Maintain the rhythmic precision of your milking cycle with this comprehensive Pulsator Service Kit. Specifically engineered for the pulsator units found in Lely Astronaut A4 and A5 robots, this kit contains the critical wear components required to restore consistent vacuum timing and liner collapse.

In a 24/7 robotic environment, the pulsator is one of the hardest-working mechanical parts. Over time, dust, moisture, and wear can cause irregular pulsation, which directly impacts teat health, cow comfort, and milk let-down. Regular servicing with this genuine-spec kit is the best way to prevent congestion and ensure a complete milk-out.

Features & Benefits

• Complete Overhaul Kit: Contains all necessary seals, diaphragms, and O-rings to fully service one Lely pulsator unit (Part #5.1004.6255.0).
• A4 & A5 Optimized: Tailored for the high-performance requirements of the latest Astronaut generations, ensuring the "rest" and "milk" phases remain perfectly balanced.
• High-Durability Materials: Components are manufactured from premium, fatigue-resistant elastomers designed to handle millions of cycles between service intervals.
• Teat Health Protection: Restores accurate pulsation ratios, preventing the teat-end damage and hyperkeratosis associated with faulty or sluggish pulsators.
• Cost-Effective Maintenance: Replacing these internals is significantly more affordable than replacing a complete pulsator assembly.

Maintenance Tip

When servicing your pulsators, ensure the air intake filters are clean and the internal housings are free of debris. A "lazy" pulsator is often caused by a combination of worn diaphragms and restricted airflow. After installing this kit, we recommend performing a pulsation test via the robot's software to verify the graph is sharp and consistent.
