How the Pump Works
The first DC spherical motor pump for direct connection to photovoltaic panels with automatic performance optimization using Maximum Power Point (MPP) tracking will vary it�s flow and power consumption based on the available solar energy.The D5 Solar can run off of as little as 1 watt and will increase in speed and performance as the solar panel output increases.
The D5 Solar pump can be used for most circulation pump applications without connection to the power grid. Highly efficient, the D5 Solar can be connected directly to a photovoltaic panel. It is characterized by its small size, high efficiency, extremely low power consumption and its over temperature safety shut off device. The shaftless spherical motor technology provides maintenance free and quiet service life. This pump is also perfect for single family home thermal solar systems or any circulation pump application where conventional power is not available.

The Principle of the Spherical Motor
Invented by Laing, it 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 D5 Solar can be easily and safely installed by following detailed instructions from a Laing Installation Guide.

DC Pumps - D5-38 Vario & D5-38 Strong

D5-38 Vario
Variable Speed
High Efficiency Magnetic Drive Direct Current Circulator

The Ecocirc electrically commuted spherical motor design offers many benefits over other pump styles. The Laing design operates on extremely low power input at a specified nominal voltage from 8 to 24 volts; the spherical permanent magnet eliminates impeller slippage which makes the Laing pump up to 40% more efficient than a standard induction motor. The motor has no shaft and therefore no shaft seal that is a wear point and potential leak path. Pump operation is virtually silent, with a low 35 db noise level. The brushless motor has a lifetime in excess of 50,000 hours when operated at nominal voltage and can be powered directly by solar panels, battery or other DC power sources. The unique screw ring design for this series of pumps allows for changing motors without disturbing the pump housing piping. The vario also features a potentiometer which allows the user to dial in the speed they need for the application.

Applications:
Solar systems
Computer cooling systems
Circulating systems for homes, RV�s and boats
Engine block circulating systems
Juice machines
Aquariums and ponds
Oxygen generating systems
Vending machines
Water fountains
Process temperature control
Remote area fluid handling
