Variable speed Hayward 1.65 THP, totally enclosed permanent motor, programmable stand-alone pump, easy to use digital control interface that can be removed from pump and mounted on a wall or other convenient location.  Built in protection for high temperatures and can withstand temperatures below freezing without issue.  This pump has been used for less than one season and has had no issues.  It is up for sale because I have a large in ground pool (approximately 42,000 gallons) and it requires a larger pump.  I discovered only after I bought the pump that it is better suited to a pool of 32,000 gallons or less, or for a hot tub.  This pump retails new for $1400.  I will sell it for $850.
