The new pumps Silence 1073.05 is electronically speed-controlled pumps operating on safety extra-low voltage.

They are ideal in any aquarium and contain a new micro-processor controlled motor, and can thus be referred to as “intelligent” pumps: The electronic motor adapts its speed automatically to the pump load and always seeks the best efficiency at the lowest possible consumption of energy. This energy consumption is about 30 per cent lower than in conventional pump motors. The pumps will be stopped immediately in case of blockage. After the blockage has been removed, the pumps will start up automatically after a delay of 20 seconds. They also comprise all other advantages of the non-controllable versions.

For example, they can be combined with Wavecontroller 7092 for operation in night mode or pulsating flow and filtration.

Fitted with Safety Connector 6105.50, they can be operated on every 10 V to 24 V direct-current source (battery, solar cell).

Silence electronic and e-jet electronic have been designed especially for low-noise operation.
  • Flow rate at 15 V: 800 to 1,800 l/h (211 to 475.5 USgal./h).
  • Flow rate at 24 V: 1,100 to 3,000 l/h (290.5 to 792.5 USgal./h).
  • Hmax. at 15 V: 1.9 m (74.8 in.).
  • Hmax. at 24 V: 3.9 m (153.5 in.).
  • Energy consumption at 15 V: max. 20 W.
  • Energy consumption at 24 V: max. 43 W.
  • Voltage / frequency: 100 – 240 V / 50 – 60 Hz.
  • Cable length: 5 m (196.8 in.).

Nice Pump

Pros: Adjustable flow and quiet

Cons: Gets a little louder than I would like at over 50% flowrate

Works great on my 40 breeder small system. Adjustable flow is really helpful.

Remove "Silence" from the Description

Pros: ease of install

Cons: extremely loud, outdated design

Wow this thing is loud. I bought it thinking it would be quieter than my Jebao 8000K but boy was I wrong. But the good news is that it made me appreciate the much cheaper Jebao brand even more. Surprising because I have Tunze powerheads and they are great. But this thing is not.

Best pump ever

I bought four different pump manufactures, looking for one that could pump around 700++ gallons per hour. Everyone that I tried at my local aquarium store turned out to be supper loud. Even the most expensive at $200 Canadian was unbearable. The tunze silence 1073.05 electronic pump is literally silent. I could not hear even though I was trying. In my 45 gallon tank there was not even a sound in the room. This pump is worth every penny. The act that you can even control the output with a simple dial is even better. Fantastic product and really the only pump to buy since its good for small and large aquariums.

Very Quiet

This is my second time buying this exact pump, not because the previous one failed, but because I will be using it in my new 70 gallon build. The other one is running just like it was new. Still very quiet & no problem pushing the water to my 50 gallon cube from the sump. The variable jumpers (included) make it very easy to get the perfect water flow & then you can fine tune it from there on an external controller included in the power assembly. The pump is expensive, but so is not having the right flow & having to use gate valves to restrict the flow. Plus, it eliminates the headache of sizing the pump. Then if you upgrade tanks you can use the pump with the higher jumper to further increase the flow. Overall, the pump is quiet & gets the job done, it is also energy efficient which saves in the long run on the electric cost.

New Technology

Say goodbye to gate and ball valves to throttle back return pumps, just turn the tiny red knob on the power connector and walla, you are at either a trickle or wide open throttle, this was great since i was leak testing my new 180g setup and would rather slowly throttle up the flow while checking for leaks. and It is close to silent! I love it!

Great pump

Flow at 4.5ft head estimated 4 to 500gph. Nice compact size, accepts 3/4inch id hose. Has power brick similar to laptop. Unique sound like lawnmower way off in distance, not loud just different. Speed control is awesome. On my kill-a-watt meter it is pulling 34watts at wall on max speed (24v). Acceptable flow thru sump even at 20watts. My eheim 1260 was pulling 58watts and is noticably stronger. If you have high head or use a single pump for multiple items stick with Eheim. Overall a great pump. Energy efficient,quiet,versatile.
