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!


Areas of Use:

 Built-In Protective Functions

  • Drive Circuitry will sense dry operation and shut down to prevent damage
  • Will slow operation or stop completely when an over-temperature 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 over-voltage condition and shut down when voltage exceeds 28V. Will recover automatically when voltage falls below threshold.



  • All Wetted Parts are Food Grade
  • Stainless Steel Pump Housing
  • Ryton Impeller
  • Viton “O” Ring
  • Ceramic Ferrite Magnet
