Piping support

The pumps are not designed to carry loads imposed by the weight of the pipeline. Suction and
discharge piping must be supported near the pump, unless otherwise specified. Pumps and
subbases can be designed to carry loads due to thermal expansion.

Foundation

The foundation must be a permanent, rigid support for the subbase or floorplate. It should be
an industrially accepted design capable of absorbing excessive vibration.
Foundations are typically concrete with anchor bolts cast in to secure the pump.
An anchor bolt assembly consists of a bolt and washer with a sleeve 2-½ times the diameter of
the bolt. When the assembly is cast in concrete, the washer prevents the sleeve and bolt from
being pulled. The sleeve I.D. provides an adjustment allowance around the bolt. A lug is
generally welded on the bolt to prevent rotation when tightening.
Anchor bolts should be located in the concrete by a template dimensioned from the pump
installation drawing. The top of the sleeve should be temporarily sealed with waste material to
prevent concrete from entering during the concrete pouring operation. A typical anchor bolt
arrangement is shown in
1. Leveling wedges or shims left in place
2. Dam
3. 19mm - 38mm | ¾ - 1-1/2" allowance for grit
4. Finished grouting
5. Subbase
6. Top of foundation left rough - clean and wet down
7. Pipe sleeve
8. Washer
9. Lug

Installing pump on foundation

If subbases or floorplates were directly anchored to poured concrete foundations, surface
irregularities would cause distortion. Rectangular metal blocks and shims, or metal wedges
having a small taper, are placed beside each anchor bolt to level the subbase or floorplate (see
Figures Leveling with wedges and Leveling with blocks and shims). The anchor bolts are then
drawn tight enough to maintain position and level.
To secure the shims in place and provide a level surface for the base or plate, grout is poured
over the concrete foundation. A 19mm to 38mm | ¾" to 1-½" grout allowance is recommended.
