Near-Silent Operation With Sine Wave Technology
Sine Wave Pattern - Electricity current alternates in a much smoother pendulum while using Sine Wave Technology to deliver powerful, efficient and reliable water movement for freshwater and saltwater systems. Designed as a versatile return pump, it offers precision control, smart feeding pauses, and pulse modes for natural flow patterns—all with whisper-quiet performance.
Features:
- 15 steps of flow speed for precise tuning
- 3 different feed mode durations in 10, 20 and 30 minute timer
- 2 different pulsing mode (Pulse mode one ranges from a minimum of 0.6 to 4.4 seconds and has a sharp start and stopping of the impeller. Second pulse mode 2 has a frequency ranging from 3 to 22 seconds)
Why aquarists love it:
- Near-silent operation thanks to advanced sine wave technology—ideal for living spaces
- Energy-efficient DC performance with high head pressure for dependable return flow
- Fine-tuned control for corals and plants, from steady return to dynamic pulsing
- Easy maintenance and versatile plumbing with multiple coupling sizes
Perfect for use as a return pump or circulation pump in a wide range of aquarium sizes, this DC pump combines quiet operation, adjustable flow control, and robust build quality to keep your system running smoothly and efficiently.
