【PVC Material】The bilge pumps are made of high-quality PVC and copper, are fully submersible, and have an airtight and moisture-proof design to prevent fire hazards. 【High Performance】The automatic bilge pumps operate quietly and without vibration, ensuring a quiet environment without having to worry about noise. Small size, high efficiency, low current, and large capacity achieve the perfect combination of small volume and high flow rate. 【Ignition Protection】The pump is protected against shock from strong currents and will not burn dry. The submersible bilge pumps have assembly and disassembly functions, making them easy to use. 【Technical Data】Pump Voltage: 12V, Flow Rate: 1100 GPH, Maximum Current: 3.8A, Outlet Diameter 29mm, Cable: 1M. 【Typical Use】Submersible bilge pumps for gravity-fed or pressure-fed in-line cold water hydraulic systems, ideal for fishing boats, sailboats, yachts, etc.
