Impeller
Highly efficient and dynamically balanced with fine ceramic bearing for smooth ultra quiet operation.
Construction
Wetted parts are food grade stainless steel, food grade thermoplastic (Viton), carbon and ceramic for superior reliability and corrosion resistance.
Over voltage protection
When the voltage over 28V, the pump will auto-protect and shut off own power supply, when the voltage falls below 28V, the pump will restart automatically.
Over load protection function
This means that when the current is over the rated current, such as can arise if the impeller is stuck due
to debris. The pump will automatically stop to prevent damage, and will restart when the current falls again.
PV operated
For solar system loops, the TD5 pump can be powered directly from a PV panel. Thesun comes up, heat builds in the solar hot water panel and at the same time electricity is made in the PV panel.The pump slowly starts with the smallest amount of current and pushes the heated water to the storage tank. It's all too simple and eliminates all controllers, thermostats and sensors.
Soft start-up
The TD5 Solar DC 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 two watt).Cycling due to unsuccessful attempts is minimized. Even after prolonged shutdown, the
pump will start reliably .
Automatic polarity protection
Red is plus, black is minus, if wrong polarity will not damage the motor for it has the automatic polarity protection function.
Application
The TD5 solar DC pump can be used for most circulation pump applications without connection to the power grid. Highly efficient, the TD5 can be connected directly to a photovoltaic panel and is characterized by its small size, high efficiency, and extreme low power consumption. The long life brushless 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.
