4.1.2 Foundation requirements
Requirements
• The foundation must be able to absorb any type of vibration and form a permanent,
rigid support for the unit.
• The foundation must weigh at least 2-1/2 times the weight of the pump unit.
• Provide a flat, substantial concrete foundation in order to prevent strain and distortion
when you tighten the foundation bolts. Tie the concrete pad in with the finished floor.
Bolt installation — pump to concrete
• Use some type of expansion fitting in order to facilitate easy servicing. Insert the
female portion into a suitable hole in the pad so that its top surface is flush with the
pad surface. Thus, when the hold-down bolts are removed, the motor can be removed
by sliding it back from the pump.

• Sleeve-type and J-type foundation bolts are most commonly used. Both designs allow
movement for the final bolt adjustment.
• Use foundation bolts and larger pipe sleeves to give room for final bolt location.
