The E-5 circulation pump part number 74427 is used for all hot spring, tiger river, limelight spas. This newer style circulation pump replaces previous version known as the Silent Flo 5000 and the Silent Flo 5002.
This pump does not come with a cord so you need the cord from your previous Silent Flo 5000 or 5002. The cord is easy to install and we would be happy to walk your through it.
110volt 3/4" Barb style fittings
This newer style circulation pump E-5 is smaller, quieter and more efficient then previous Silent Flo 5000 and Silent Flo 5002 models. It has a self priming mode as well that will shutdown if it is unable to grab prime giving add protection to the pump.
We also offer (and frankly suggest) the E-10 circulation pump which has a slightly high volume of water flow but otherwise offers the same features and benefits of the E-5.
