✅ Key Differences:

EN118473 covers a wide range of Series 60, 1522, PD, and MF 60 pumps including many low-HP inline and tri-volt options.
EN118705 is designed for higher series / larger pumps (Series 100, HV, PR, 2") and is more focused on standard circulators.
Both are spring-type couplers engineered to absorb vibration, reduce noise, and ensure smooth pump operation.
