The SWD-4000 is a circulation pump for hobbyists running marine or freshwater aquariums, or garden ponds, who want flow adjusted to the tank rather than a fixed setting. Its built-in controller lets you set the output and pause circulation during feeding without changing the installation.
Why it matters
- Adjustable flow: the controller regulates output smoothly from 30% to 100% of power, within a rated range of 1200 to 4000 l/h.
- Feeding mode: a 10-minute pause can be activated during feeding, and the pump can also be switched fully on or off.
- Lower power draw: the six-pole, multi-voltage motor reduces current consumption when output is reduced; the manufacturer states that consumption can drop by up to 70% together with output.
- Seawater-compatible shaft and protection: the ceramic shaft allows use in seawater, and the built-in IC protection shuts the pump off if water is lacking or the impeller becomes blocked.

What it works with
The pump is designed for circulation in marine aquariums, freshwater aquariums and ponds, and is suitable for both submerged and external setups where water reaches it by gravity. Its 3.5 m head and 4000 l/h maximum flow define the range of installations it can serve. Match the flow setting to the volume and the livestock in your system, using the controller to fine-tune it.

Frequently asked questions
Yes. The pump suits marine and freshwater aquariums as well as ponds, and its ceramic shaft allows it to be used in seawater.
Yes. It can operate fully submerged or be installed outside the water and connected to the water circuit, but in that case water must reach the pump by gravity.
The built-in controller adjusts power smoothly from 30% to 100%, lets you switch the pump on or off, and sets a 10-minute pause for feeding time.
An integrated IC protection circuit monitors operation and cuts the power if there is no water or the impeller becomes jammed.
The flow ranges from a minimum of 1200 l/h to a maximum of 4000 l/h, and the water lift height is 3.5 m. Power consumption is between 10 W and 35 W.
