Sun-Ray Brochure (PDF, 768K) User Manual (PDF, 1.9M) The Monoflo Sun-Ray solar pump has been designed to transfer surface water with the same efficiency and reliability as other Monoflo solar pumps. Available with either a stationary or GPS Tracking array, ranging from 150W to 1575W, the Sun-Ray can deliver very high daily flows up to discharge pressures of 120m. The highly efficient, helical rotor pump is inherantly self-priming, so the pump can be positioned up to 6m above the water source, allowing the pump to be installed on top of dam walls or on river-banks above the high water mark. The Sun-Ray is suitable for pumping water from springs, rivers, tanks and dams. It is available with a floating pontoon that has been designed to safely enable the pump to float on a dam or other water source. The PC (Progressive Cavity) helical rotor pump element used in the Sun-Ray pump is proven to provide maximum water output even in water containing silt or iron oxide, and low pump speed means extended rotor and stator life in abrasive bores. The PC pump will deliver water with every rotation regardless of speed; on solar, when pump speed will vary with the amount of sun, it is important to get water with every turn of the pump.   All Sun-Ray systems are supplied complete with pre-wired solar modules, array frames, pump element, submersible motor and solar motor controller. The entire package is easy to assemble and all electrical connections are fitted with plugs & sockets, so electrical connections do not require an electrician.   Float and/or pressure switch input enables complete system automation. The Sun-Ray will only pump as long as water is needed and will stop once tanks and troughs are full. Applications Surface water transfer Remote water supply for agriculture / livestock Medium scale irrigation Remote domestic water suppply Aqua culture Features Solar power - no fuel costs, maximum output in sunny conditions when you need it most Self contained - no need to connect AC power or transport fuel Simple design, proven technology - you can rely on it Supplied as a complete package - easy to install Helical rotor pump - highly efficient, self priming The rate at which water is pumped can be limited to suit the water source Brochure (PDF, 768K)User Manual (PDF, 1.9M)

 D5 Solar Water Pump
Laing Thermotech
Hot Water. Hot Savings.
•Start-up Power Requires Less Than 1 Watt
•Directly Connects to P.V. Panel
•Economic and Powerful
•Wide Variability
•ECM Technology
•Shaft-less Spherical Motor
The first DC spherical motor pump for direct connection to photovoltaic panels with
automatic performance optimization using Maximum PowerPoint (MPP) tracking.
Application
The 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 Maximum
Power Point (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.
Design
The principle of the spherical motor, which was
invented by Laing, is fundamentally different from
conventional canned motor pumps. The only moving part in
a spherical motor is a hemispherical rotor/impeller unit which
sits on an ultra-hard, wear-resistant ceramic ball. There are no
conventional shaft bearings or seals. This eliminates 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.
Maintenance is not necessary under normal conditions. Even
after prolonged shutdown, the pump will start reliably. All
parts exposed to the fluid are completely corrosion resistant.
Soft Start-up
The Ecocirc Solar pump has a soft start-up feature which
reduces high in-rush current. 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). Cycling due to
unsuccessful attempts is minimized. Even after prolonged
shutdown, the pump will start reliably.
Over-temperature Safety Device
(Brass Pump Housing Only)
The Ecocirc Solar pump comes with an integrated
over-temperature safety device which shuts off the pump
electronics when reaching temperature over 230°F. When the
temperature of the pumped fluid is below 203°F the pump
will function normally. The temperature of the electronic
components is influenced by the temperature of the pumped
media as well as 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 (e.g.
caused by too hot pumped media), the pump will eventually
shut down completely. After cooling down, the pump will
restart automatically.
Automatic performance optimization -
Maximum Power Point (MPP) tracking
The Ecocirc Solar pumps are the first and only spherical
motor pumps with self-optimizing performance to
maximize use of available power of a solar PV panel. 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. This is called the “Maximum
Power Point” (MPP). 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.
