DEKO Submersible Water Pump 400W
Product description
If you need reliable water drainage for a pool, pond, or garden area, the DEKO submersible water pump is built for practical clearing jobs. With a 400 W motor and a maximum flow rate of 8000 l/h, it helps move water efficiently when you want the area emptied or the drainage controlled. It is also designed to handle clean and dirty water, with a maximum solid passage size of 35 mm, so day to day mess does not automatically become a blocker. ✅
The essentials

The DEKO Submersible Water Pump 400W is a portable sump pump that sits under the waterline to pump water away. Because it is submersible, it is suited to draining pools, emptying areas after heavy rain, and clearing water from ponds and garden features. The setup is supported by a float switch, which can detect the water level and switch the pump off when the water drops below the preset point. That reduces the chance of running the motor unnecessarily, and it also helps keep the pump working within safer operating conditions.


A key part of the value here is how the pump is described as handling both clean and dirty water. It is stated to pass solids up to 35 mm, which matters when you are dealing with sludge, leaves, or general debris. It also has thermal protection that automatically switches the pump off when the motor heat exceeds 35 °C, then returns it to operation after cooling. In other words, it is designed to keep working in real environments rather than only ideal, clean-water scenarios. 🌿

It is not just about draining one type of tank either. The pump is described as broadly useful for water discharge from ponds, pools, farms, fountains, and water tanks, along with underground drainage and pumping irrigation. The power cable is stated to be 10 m long, which can make positioning the unit easier when you are working around a garden or water feature. For day to day maintenance and clearing jobs, that kind of practical reach often saves time.
Key features



This pump brings several engineering choices together that support drainage tasks. The motor power is listed as 400 W with a maximum flow rate of 8000 l/h, and the maximum pump height is stated as up to 5 m. The maximum immersion depth is described as 7 m, which helps if the water level sits lower or the sump area is deeper than expected. For many common draining needs, those figures provide a useful starting point when planning how quickly the water can be moved. 🔧
The float switch is an important operational feature. It is described as automatically detecting the water level, switching the motor off when the water drops below the preset value to avoid running on when there is little left to move. The description also notes that manual control can continue drainage when needed, which is helpful if you want to finish a job thoroughly rather than relying solely on the automatic cut off. It is worth noting that the level of water after drainage is stated as not higher than 35 mm, so it is best to treat this as a close draining solution rather than expecting a perfectly dry surface.

For dirty water use, the pump is described as passing solids up to 35 mm in diameter. That can be particularly relevant for garden ponds and pool drainage where debris may collect. Another practical detail is the output and connection options. It includes multiple hose sizes and a threaded pipe connection, with listed sizes of 1 inch, 1-1/4, G1 inch, and G1-1/2 inches. You can choose a connection size according to flow needs, and then use hose clamps or hose threading to fit the drainage hose securely.


The thermal protection is described as integrated, automatically shutting the pump down when motor heat exceeds 35 °C. After the motor cools, the pump will resume pumping. This kind of protection is useful for preventing overheating during longer drainage sessions, especially if the pump is running continuously while water clears away. Overall, these features support both convenience and controlled operation. 🧰

What it’s for
It makes sense if you want a submersible pump for practical drainage around the home and garden. You will likely like it if you regularly handle pool draining, pond emptying, or clearing water from sumps, ditches, and garden water features. It is also described as useful for pumping irrigation and residential water supply, so it can fit a variety of routine water handling needs.
It might not be a great match if your priority is specialist, fully precision draining with extremely low residual water, because the description gives a post drainage water level of not higher than 35 mm. You may want to skip it if your setup requires connections outside the listed hose and threaded pipe sizes, as the connection options here are described as 1 inch, 1-1/4, G1 inch, and G1-1/2 inches. If you are comfortable choosing the correct hose size and managing the drainage hose length, this pump is positioned for those everyday clearing jobs where both clean and dirty water are common.
