DCP4000 Aquarium Water Pump with DC Controller, Ultra Quiet Adjustable Submersible Pump

Product overview A versatile DCP Pump designed for reliable liquid transfer in seawater and freshwater environments. Compact, energyefficient, and lownoise, this pump is suitable for aquariums, fountains, cooling systems, and industrial liquid handling. Key specifications Color: Dcp4000 Input voltage: 100V240V Power options: 23w, 25w, 40w, 55w, 65w, 80w, 95w, 105w, 135w, 165w Head (outlet length options): 2.5m, 3.0m, 4.0m, 4.5m, 5.5m, 6.0m, 6.5m, 7.0m, 9.0m, 9.5m Flow rate options: 2500L/H, 3500L/H, 5500L/H, 6500L/H, 8000L/H, 1000L/H, 13500L/H, 15000L/H, 18000L/H, 20000L/H What is included 1 PCS DCP Pump Performance and design benefits Energy efficient motor with frequency conversion electronic control that reduces energy use by approximately 65 percent while maintaining steady output. Ultraquiet operation for use in noisesensitive environments. 10minute delay restart function: if feeding or supply is interrupted, the pump will wait 10 minutes before restarting to protect connected systems. Memory function: the pump retains its operating parameters during a power loss and restarts using the previous settings. Wearresistant ceramic shaft for extended service life and reduced maintenance. No copper components in contact with water, making the pump suitable for both seawater and freshwater applications. Reflux valve design protects the system when the outlet is blocked: the motor continues running while the reflux valve opens to circulate water internally, preventing pressure buildup. Practical advantages Wide range of power, head, and flow options lets you select the model that matches system requirements for head pressure and flow volume. Stable, lownoise performance enables installation near living spaces, office areas, or production lines without disruptive sound. Durable construction and ceramic shaft minimize downtime and maintenance costs in continuoususe applications. Recommended use scenarios Aquarium systems and fish tanks: maintain circulation and filtration in freshwater and marine tanks without copper exposure. Garden fountains and water features: reliable flow control and low noise for outdoor ornaments and landscape installations. Industrial liquid handling: sewage sampling, volume liquid transfer, and watercooled equipment where continuous, lownoise pumping and corrosion resistance are needed. Important notes This pump features a reflux valve design. If the water outlet becomes blocked, the motor will continue to run but the reflux valve will open and water will circulate inside the pump. Choose the appropriate power, head, and flow rate combination to match your installation requirements.
