I have a Speck Badu-MV 2.4HP variable speed pool pump. This was the very same pump as the Circupool VJ-3 pump a few years ago. Since then they have switched to a Century motor with more electronic control versatility. The pump was rated as the 2nd most efficient pump behind only the Hayward Ecostar VSP 2300 and better than the Pentair Intelliflo. It is easy to program and has been running 24/7 for 3 years without issue. If I had to buy a new pump today I would not hesitate to buy a new Circupool variable speed pump.
