Concrete Inertia Bases | Vibra-Sonic Control

The primary purpose of the concrete inertia base is to provide strength in order to limit excess movement, and only on large pumps over 75 HP does the mass of the inertia base also become critical for mitigating vibration, so even on systems with only 3 or 5 horsepower you run the risk of putting strain on the coupling if mounting directly on
