CQHPUI-356 | Hydraulic Power Unit Isolation Pads for 2,300 – 4,000 lb. Power Units

Minimizing structure-borne hydraulic elevator sound migration requires detailed attention to isolation of each system component, from the power unit to the rail guides.
A quality muffler installed will greatly reduce the sound carried through the fluid; however, the equipment generated sound energy will travel through the steel of the pipe. The hard, rigid steel-on-steel mechanical connections provide an ideal migration path the entire pipe length to the cylinder.
CQuiet Hydraulic Pipe Stand Isolation provides effective isolation of the pipe stand assembly. Isolation of the pipe is a full pipe wrap strip, support base pad, and isolated washer to prevent a short circuit through the anchor.

Hydraulic pipe wall penetrations are a frequent point of noise migration. Often the penetration opening is unfilled or improperly filled with a non-fire rated material. Physical contact of the pipe and wall allows structural migration of the systems noise.
Common filler materials provide no significant noise barrier properties or fire protection. CQuiet Firestop Noise Putty provides isolation and high noise blocking properties for wall penetrations around hydraulic pipes.
