The Jebao SLW-20 Sine Wavemaker Pump is ideally suited for nano reef aquariums, with adjustable flow rates up to 10000 L/H. The SLW pump is unique in terms of the construction of the head, which is extremely flat. In addition, the pump is mounted directly on the glass, significantly saving space in the aquarium making it less visible.

There are no electronic components in the pump, everything is in the controller. It also has a sine wave technology which results in quiet operation.

• External Drive Controller, no electronic devices inside of pump for a longer life
• Small size and super quiet motor
• 5 wave modes, as well as a built-in master & slave function
• Big rotation angle to adjust the output water direction
• Night mode - reduces pump performance at night, reflecting natural tidal waves
• Feeding mode - turns off the pump while feeding fish or corals. The pump switches on automatically after 10 minutes starting the pre-programmed operating mode
  
• Power: 20w
• Adjustable Flow Rate: Up to 10000 litres per hour
• Suitable for glass thickness of up to 10mm
• Dimensions: 70mm Diameter x 55mm Deep
• Voltage: Input: 100-240v, 50/60Hz: Output: 0.7A 24v

The operating modes:
W1: Wave Mode flow can be adjusted by using the Speed/Feed button. The wavelength can be increased by switching the knob in clockwise and reduce it anticlockwise
W2: Sine Wave Mode the pump smoothly changes its efficiency from 30% to 100% in the sine wave pattern, natural looking waves are generated
Else: Random Mode the power of the pump is changing randomly without the need for regulation
H: Flow Mode the pump produces a constant stream of water current. Flow rate can be adjusted using the Speed/Feed button
C: Shift to Flow Mode - Two pumps are required for this operation to shift wave and flow in cycles
