LF SPRING ø 8x30 mm for Professional Espresso Machines

A precision-engineered spring maintains the tension needed for consistent espresso extraction. In lever-operated and semi-automatic espresso machines, the spring counterbalances the force applied to the group head, ensuring steady pressure on the coffee puck. Without this resistance, the lever would drop too quickly, under-extracting the coffee and producing a weak, sour shot. The spring's calibrated tension allows the barista to control the pre-infusion and extraction phases, delivering the rich crema and balanced flavour expected in professional espresso.

To replace the spring, the machine is first switched off and unplugged. The group head is disassembled to access the spring housing, typically located behind the lever mechanism. The old spring is removed, and the new one is seated in the same position, ensuring it aligns with the guide posts. Once reassembled, the lever is tested for smooth, even resistance. The spring's performance is verified by pulling a test shot, adjusting grind and dose as needed to match the machine's original extraction profile.

Constructed from durable spring steel, this component is designed to withstand repeated compression cycles under high pressure. Its dimensions—8 mm in diameter and 30 mm in length—match the specifications of the original parts used in the listed espresso machines, ensuring a secure fit without modification.

This spring fits a wide range of commercial espresso machines, including models from BFC, Brasilia, Carimali, CIME, Faema, Fiamma RST, Futura, Futurmat-Ariete, Gaggia Spagna, Grimac, Italcrem, Mairali, Royal, Scala, Spaziale, Vibiemme, Visacrem and Zola-II. Specific models include the Faema E61, Brasilia Century, Spaziale S1, Vibiemme Domobar and many others across these brands.

As a spare part, it is categorised under espresso machine components, specifically for lever and group head assemblies.
