3. It is recommended to build foundation approximately 3 inches (76 mm) larger overall than the pump
baseplate to provide ample anchorage for the foundation bolts.
3.1. Since water can accidentally flow in the floor, a height for the surface of the foundation of 4 inches (100
mm ) at least above floor level is recommended.
4. Use a template to accurately locate foundation bolts according to the General Arrangement.
4.1. Choose foundation bolts of size specified in drawing (ASTM A36, M 1020 and ASTM A575 are
recommended); they should be long enough to allow a minimum of two threads above the nuts.
5. Provide pipe enclosures for the bolts, which are three or four diameters larger than the bolts.
6. Protect area around the bolts from contact with the concrete.
7. Pour the concrete and provide a chamfer at all corners.
8. Allow concrete to cure completely (at least seven days) before preparing the surface for grout preparation.
4.2 LEVELING BASEPLATE
Before leveling the unit onto the foundation, the following preparations must be made:
1. Chip away all damaged concrete with a hammer and chisel, eliminating about one inch of the
surface of the foundation. After surface chipping is done, the foundation shall be thoroughly cleaned
free of debris. Clean the anchor holes.
2. Check that the placement and dimensions of the foundation and the anchor holes correspond to the
assembly plan.
