NOTICE:
Slurry Pumps are typically driven with motors mounted overhead, coupled with V-belts and
sheaves. This configuration does not require the pump to be mounted and grouted into place.
The pump pedestal can be bolted onto a concrete foundation using J-type bolts or Sleeve-type
bolts, thru the pedestal or mounting feet.
4.2 Baseplate-mounting procedures
4.2.1 Prepare the baseplate for mounting
1.
Remove all the attached equipment from the baseplate.
2.
Clean the underside of the baseplate completely.
3.
If applicable, coat the underside of the baseplate with an epoxy primer.
Use an epoxy primer only if using an epoxy-based grout.
4.
Remove the rust-proofing coat from the machined mounting pads using an appropriate solvent.
5.
Remove water and debris from the foundation-bolt holes.
4.2.2 Install the baseplate using shims or wedges
Required tools:
•
Two sets of shims or wedges for each foundation bolt
•
Two machinist's levels
•
Baseplate-leveling worksheet
This procedure is applicable to cast iron and fabricated steel baseplates.
1.
If you use sleeve-type bolts, fill the bolt sleeves with packing material or rags to prevent grout from
entering the bolt holes.
2.
Put the sets of wedges or shims on each side of each foundation bolt.
The sets of wedges should have a height of between 19 mm | 0.75 in. and 38 mm | 1.50 in.
