This pump can be powered from any 12V source or directly from a PV Solar Panel. In Solar applications having the pump powered directly from a PV panel assures that the pump power is controlled by the intensity of the sun. This can completely eliminate the need for controllers, thermostats, and sensors.
Since the pump can also be powered from 12V sources it is suitable for a host of applications in cars, boats, and RV's that require high temperature and pressure capability, or anywhere where connection of your plumbing system to hazardous grid power voltages is not desirable.

This pump fully complies with the new Federal "Lead Free Plumbing" laws!

Built-In Protective Functions

  1. Drive Circuitry will sense dry operation and reduce pump output to prevent damage
  2. The pump will slow operation or stop completely when it senses an overtemperature condition. This can arise due to excessive fluid temperature or excessive ambient temperatures. The pump will automatically recover when temperatures return to a safe level.
  3. The pump is protected against overload conditions, such as can arise if the impeller is stuck due to debris.
