PUMP & COMPRESSOR NOISE
Pumps are often noisy because they are sitting directly on a lightweight base with no anti-vibration insulation between. Installation of our anti-vibration mat between the bottom of the pump and the base on which it sits will absorb much of the vibration based noise often experienced. This can be further enhanced if a patio slab is placed on top of the anti-vibration mat, another layer of anti-vibration mat glued to the slab with the pump attached to a layer of MDF or ply which in turn is glued to the anti-vibration mat. Particularly effective when applied to domestic shower pumps.
Airborne noise may also be a factor to be addressed and for this we recommend the pump is enclosed within a sound insulated box. 12mm MDF or thicker is good for this and can be lined on the inside with our SA25FF/B/6 Sound absorbing foam and Barrier laminate. (See illustration below) This insulation is nominally 33mm thick so the box will have to be of a suitable size to accommodate this. A larger enclosure will give more effective noise reduction.

Ventilation
If the box requires ventilation we would advise designing it in a similar way to the drawing on the left.
