SC Solar Pump
Spherical Motor Pump
Application
• The ecocirc solar pump can be used for most circulation pump
applications without connection to the power grid with direct
connection a photovoltaic panel.
• This pump is perfect for single family home thermal
solar systems or any circulation pump application where
conventional power is not available.
Design
• The only moving part is a hemispherical rotor/impeller unit
which sits on an ultra-hard, wear-resistant ceramic ball.
• There are no conventional shaft bearings or seals eliminating
bearing noise and seal leaks.
• This pump is robust and has an estimated service life in excess
of 50,000 hours.
• The self-realigning bearing is lubricated and cooled by the
media.
• Even after prolonged shutdown, the pump will start reliably.
• All parts exposed to the uid are completely corrosion resistant.
Soft Start-up
• When the photovoltaic panel provides suffi cient power, the
pump goes through the alignment phase by turning the rotor
into the position required for start-up.
• The processor then waits until the capacitor is suffi ciently
charged.
• This enables a start-up with minimal power (less than one watt).
Over-temperature Safety Device
• The ecocirc 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 uid is below 203°F the
pump will function normally.
• The temperature of the electronic components is in uenced
by the temperature of the pumped media and by the speed
setting.
• 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.
