This is a External Reeflo pump that we used to run a large MTC skimmer for a short period.  Pump is 115 volt and  .12 horse power.  Pump runs super quiet and is ready to be put to use. It is mounted on a piece of 1/2 acrylic which could easily be removed.   Pump has a 2" inch intake and a 1 1/2"  return.
