  • Fully submersible pump – 500 US gallons per hour – 31 liters per minute.
  • Higher flow-optimized impeller to provide greater flow at the same amperage as the previous model.
  • High efficiency, low amp draw, ignition protected motor includes true Electromagnetic suppression (EMC).
  • 16 gauge tin coated copper electrical wiring with silicone infused water blocking feature to stop water wicking down inside the wiring.
  • Built-In thermal cut-out (TCO) in the motor provides additional protection for pump & vessel.
