FEATURES

Laing D5 SOLAR/720B Solar Circulator

This D5 solar pump can be used for most circulation pump applications without connection to the power grid but with direct connection a photovoltaic panel.  It is perfect for single family home thermal solar systems or any circulation pump application where conventional power is not available.  The D5 Solar pump comes with an integrated over-temperature safety device which shuts off the pump electronics when reaching temperatures over 230°F.  When the temperature of the pumped fluid is below 203°F the pump will function normally.  After reaching a critical temperature 203°F the pump will lower its speed automatically in order to avoid a total shutdown.  However, if the temperature continues to rise the pump will eventually shut down completely and automatically restart after cooling down.
