The D5 Vario compatible with a battery as well as solar panel. If using on a solar panel you would only need to adjust the speed setting.

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.

Over-temperature safety device

• The pump comes with an integrated overtemperature safety device, which shuts the pump electronics off when reaching overtemperature. Normally the temperature of the pumped media during operation at the highest speed setting is 95°C at this point.A complete shutdown after reaching overtemperature condition can result in adverse effects on the circulating system.
