A freestanding baseplate should be designed to properly support a pump and driver/ This type of baseplate must be designed to provide its own rigidity, as there is no grout for additional support.

The desirable features of a freestanding baseplate are:

  • No need for concrete foundation pads.
  • An allowance for height adjustment can easily be included.
  • Spring mounted bases provide vertical displacement under applied loads associated with thermal expansion of the piping.
  • Slide bearing plates may also be provided below the stilts or springs to allow horizontal displacement associated with thermal expansion of the piping

The purpose of a baseplate is to provide a foundationunder a pump and its driver that maintains shaft alignment between the two. It must:

  • Allow for initial mounting and alignment of equipment
  • Survive handling during transportation to the installation site.
  • Be capable of proper installation with minimum difficulty.
  • Allow final alignment of the mounted equipment and allow removal and reinstallation of equipment.
  • The baseplate must not be permanently deformed after the equipment is mounted at the manufacturing facility.
  • A free standing baseplate must be rigid enough to maintain coupling alignment when subjected to loads from piping or motor torque.
    • The rigidity shall prevent no more than 0.25-mm (0.010-in) parallel coupling misalignment
    • And 0.005-mm/mm (0.005-in/in) angular misalignment when subjected to maximum motor and piping loads simultaneously.
