    Laing Ecocirc solar pumpLaing Ecocirc Solar DC Pump Model D5 solar 090 BLead Free Brass*
    Solar Circulator 1/2" Union Sweat

    The first DC Spherical motor pump for direct connection to photovoltaic panels with automatic performance optimization using Maximum Power Point (MPP) tracking to adjust to variable wattage input. The Laing Ecocirc solar pump can be used for most circulation pump applications without connection to the power grid. Highly efficient, the Ecocirc solar can be connected directly to a photovoltaic panel and is characterized by its small size, high efficiency, extreme low power consumption and its MPP tracking. The shaftless spherical motor technology provides maintenance free and quiet service life. This pump is perfect for single family home thermal solar systems or any circulation pump application where conventional power is not available.

    Product Application
    The D5 solar pump can be used for most circulation pump applications without connection to the
    power grid but 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.

    Product Features:
    The only moving part is a hemispherical rotor/impeller unit which sits on an ultra-hard, wearresistant
    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 fluid are completely corrosion resistant.

    Soft Start-up
    When the photovoltaic panel provides sufficient 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 sufficiently charged.
    This enables a start-up with minimal power (less than one watt).

    Over-temperature Safety Device
    The D5 Solar pump comes with an integrated over-temperature safety device which shuts off the
    pump electronics when reaching temperatures over 230F.
    When the temperature of the pumped fluid is below 203F the pump will function normally.
    The temperature of the electronic components is influenced by the temperature of the pumped
    media.
    After reaching a critical temperature 203F 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.

    Maximum Power Point (MPP) tracking
    Every three seconds the processor will modify its operating point
    on the voltage-current curve of the PV panel to find the point
    of maximum performance. At this point, the pump achieves the
    maximum rpm and therefore the maximum performance. There
    is no need for a separate performance device. The ecocirc Solar
    pump will always find its best operating point under any given
    light and temperature conditions.

    Typical Current-Voltage-curve of a photovoltaic panel. By employing MPP
    tracking every three seconds, the D5 pumps always automatically achieve
    maximum performance at any given insolation.
