Xylem Information on Pads: Pads
Pumps are usually not anchored directly to floors, whether the floor is the slab-on-grade concrete floor, or an above-grade floor or the building roof. If installing a pump on the slab, housekeeping pads are used to elevate the pump and faciliate anchoring bolts. When mounted above the slab, or, when extra vibration control is needed, pumps are mounted on inertia bases. Concrete pads, also called housekeeping pads, are typically 4-in. high, but the height depends on the size of the anchor bolts. Housekeeping pads provide a solid anchor, protect the pump and motor from shallow floods and floor cleaners, and help keep feet away from moving machinery. Housekeeping pads usually extend past the pump 6-in. on all sides, which provides room for service. Inertia bases are used when floor-mounted pumps are on floors above grade – such as rooftops and mid-floor equipment rooms. They may also be used in noise/vibration-sensitive environments, such as performing arts centers and research laboratories. Inertia bases consist of heavy-duty metal frames and vibration isolators, and they form a cavity that is filled with concrete or non-shrinking grout for additional stability. Because they cost more than concrete pads, engineers should only specify them when they’re really needed.
