PUMP EXECUTIONS

Depending on pump room configuration, there are four possible pump executions.

  • Execution A – Standard execution, whereby motor is directly mounted on motor pedestal on pump
  • Execution B – At large pump units motor is mounted on pump room floor
  • Execution C – If project demands, complete pump is suspended from motor pedestal
