Topsflo TD5 Solar DC Circulation Pump
Finally an affordable full Stainless Steel Solar Circulation Pump!!
This pump has been designed to provide versatility and performance not available in any other high temperature DC operated pump. It can be powered from any fixed (6V - 24V) source or directly from a PV Solar Panel. The power level can be manually selected or the pump can automatically optimize power draw from a PV panel for maximum flow rate using advanced MPPT (maximum power point tracking) technology.
When powered from fixed sources it is suitable for a host of applications in cars, boats, and RV's that require high temperature and pressure capability. In Solar Water Heating systems this pump can be connected directly to a PV panel eliminating the need for any controllers and sensors.
This pump fully complies with the new Federal "Lead Free Plumbing" laws!

Built-In Protective Functions
- Drive Circuitry will sense dry operation and shut down to prevent damage
- Will slow operation or stop completely when an overtemperature condition is detected. This can arise due to excessive fluid temperature or excessive ambient temperatures. The pump will automatically recover when temperatures return to a safe level.
- Protected against overload conditions, such as can arise if the impeller is stuck due to debris.
- Will detect overvoltage condition and shut down when voltage exceeds 28V. Will recover automatically when voltage falls below threshhold.
