Anti-vibration mounts for pumps

Centrifugal and booster pumps spin fast, often at 2,900 rpm, and pass their vibration to the base, the pipework and the building. Well isolated, the noise stays in the pump room.

What to consider

Speed: at 1,450 or 2,900 rpm a medium natural frequency mount is enough to isolate more than 90 %.
Common base for pump and motor: the mount goes under the base, not under each part.
Flexible connectors on the inlet and outlet pipes: otherwise vibration travels through the water and the pipe.
