It has a Soft Start: pump gradually increases flow rate until the set value is reached.
It can be ramped up or down by single 1% changes on the controller.

Internal Memory: settings are retained even in the event of power failure.

The blue display will show the wattage used as well as the pumps power usage in percentage increments.
The threads are standard, so it will fit standard plumbing out of the box.

Elos calls it their silent pump, but I would not say that it is as quiet as my M1 Vectra.
If you are looking for a truly silent pump the Vectra M1 and the COR series would be the way to go.
This Elos SF11000 has a light "whir" to it at higher speeds, but would serve well in a stand with doors on it.
My only gripe with the pump was that it is not truly a dead silent pump.

Lastly, I can make a youtube video of the pump running and its operation.

It was purchased new (fall of 2017, August) from an aquarium supply store in the Carolinas that carries the Elos brand of DC pumps.
Search for or google Landedinmyeye (Flickr username) will show the history of when I brought it home.

Additional photos for Elos pump inlet and outlet information.

The Elos 1-1/4 hose adapter (outlet) is smaller than using the threaded outlet on the pump.
For better flow, I would start directly to a ball valve (with a built in union), then connect to a silicon hose to dampen vibration, then connect to hard plumbing.
Servicing/cleaning a pump should be easier this way.

- In the photo (edited with arrows), the Elos SF11000 1-1/4 inch inlet hose adapter is shown inside of standard 1-1/4 piping.
A small step or shoulder is seen.

I'd recommend using the standard pipe thread to allow more flow than using the included hose adapter.

See included photos.

Still available.
I no longer have sumps with this style of submerged pump.

Digital speed increments of 1%.
The pump will ramp up slowly from the custom timed feed mode, then back to 100% if needed, or run at the lowest operating speed of 15%.

It's a nice pump for what it is and avoids the bluetooth connectivity route for users in that direction.
 
ELOS DC PUMP.
- from the fishroom closet of odds and ends.
- I have been pulling equipment out of storage boxes and trying to relist them this season.

Thanks for looking.

>>> Scroll up for many details on the pump.
I may have some Cepex and Spears valves (ball and gate) that may fit your application too.

We no longer have sump related aquariums and run a planted tank with a canister.
