In modern industrial production environments, the fire pump room serves as a critical safety facility, and its operational stability directly affects the overall safety performance of the building. However, during actual operation, the mechanical vibration generated by fire pumps is often transmitted through the building structure, adversely affecting the upper floors, particularly precision production areas.
Liva Environmental Technology (Shanghai) Co., Ltd. has completed a comprehensive vibration control project for the basement fire pump room of a semiconductor facility in Suzhou, thoroughly resolving the issue of pump vibration interfering with the upper-floor dust-free precision workshops. All performance indicators have met the required standards, earning high recognition from the client.

Spring Isolators
1. The outer frame features a zinc‑aluminum surface treatment, while the spring surface is powder‑coated, providing excellent corrosion resistance, with both having passed ASTM B‑117 and CNS 8886 salt spray tests.
2. The spring diameter is greater than 0.8 times the height at rated deflection, and the spring compression at solid height exceeds 50% of the rated deflection.
3. The springs undergo heat treatment and stress relief processes, offering excellent fatigue resistance with a recovery rate exceeding 99%.
4. A retaining bolt design maintains a 12‑mm clearance from the outer frame to prevent vibration transmission.
5. A 6‑mm thick synthetic rubber pad at the base provides sound absorption and anti‑slip functions.
6. A pressure pad design fixes the operating height for simple installation.
Suspension Isolators
1. Compact and robust design, safe and durable.
2. Effectively isolates low‑frequency noise generated by vibration, providing high isolation efficiency.
3. The suspension frame and springs are treated with multi‑layer rust protection and have passed salt spray tests.
4. Designed with an anti‑slip rubber base for the spring.
After the retrofit by Liva Environmental Technology (Shanghai) Co., Ltd., the post‑installation measurement data showed remarkable results: the peak vibration level in the cleanroom was attenuated by up to 90%, and all measurement points stably met the VC‑C micro‑vibration standard for semiconductor facilities, with equipment jitter completely eliminated. The entire solution required no modifications to the existing fire protection piping, was adapted to the humid basement environment, and offered easy maintenance over the long term.
