    Description

    Automatic Bilge 12V Solar Pump

    Automatic Water Removal for Boats, Bilges & Drainage Applications

    Keep unwanted water under control with the Automatic Bilge 12V Solar Pump, a compact and practical solution for removing accumulated water from boats, bilges and other suitable drainage areas.

    Designed with an automatic water detection function, this 12V DC bilge pump can detect rising water levels and activate when water needs to be removed. This makes it especially useful for applications where water may collect unexpectedly.

    With a maximum flow rate of 4,100 litres per hour and a maximum pumping head of 4 metres, the pump provides efficient water removal in a compact design.

    Its durable ABS housing is designed for wet environments, while the built-in motor provides reliable pumping performance for suitable marine and drainage applications.

    Whether you're removing water from a fishing boat, managing water accumulation in a bilge or setting up a compatible low-voltage drainage system, this automatic pump offers a convenient way to keep water moving.

    Why You'll Love It

    • Automatic Water Detection: Activates when water is detected, helping remove unwanted water without constant manual operation.

    • Maximum Flow Rate of 4,100 L/h: Designed for efficient water drainage.

    • Maximum Head of 4 Metres: Suitable for compatible low-head pumping applications.

    • 12V DC Operation: Ideal for boats and other suitable low-voltage systems.

    • Solar Compatible: Can be used with a correctly configured 12V solar power system.

    • Durable ABS Housing: Lightweight, water-resistant construction for wet environments.

    • Compact Design: Convenient for installation in areas where space is limited.

    • 25 mm Outlet: Connects to compatible discharge hoses.

    • 75 cm Power Cable: Provides flexibility when positioning the pump.

    • Easy Installation: Universal mounting hole positions allow for straightforward fitting.

    • Low Maintenance: Designed for convenient inspection and cleaning.

    Ideal for Boats & Water Drainage

    The Automatic 12V Bilge Pump is designed to help remove accumulated water from suitable areas.

    It's particularly useful for:

    • Fishing Boats: Remove water that collects in the bilge during normal use.

    • Small Boats & Runabouts: Help manage unwanted water accumulation.

    • Marine Bilge Systems: Provide automatic drainage when water is detected.

    • Water Drainage Applications: Transfer collected water from suitable low-voltage drainage systems.

    • Aquariums & Water Features: Suitable for compatible water transfer applications where the pump's materials and operating requirements are appropriate.

    • Off-Grid Drainage: Operate from a correctly configured 12V battery or solar-powered electrical system.

    Automatic Water Detection

    One of the most useful features of this pump is its automatic water detection system.

    Instead of relying entirely on manual switching, the pump is designed to activate when incoming water is detected.

    This helps remove accumulated water and makes the pump convenient for installations where water levels may change.

    For best results, position the pump at a suitable low point where water naturally collects, while ensuring that the inlet remains clear of debris.

    Please note: Automatic bilge pumps are intended to assist with water removal and should not be relied upon as the only protection against flooding or water ingress.

    Durable Construction for Wet Environments

    The pump features a durable ABS housing designed to withstand regular exposure to water in suitable marine and drainage applications.

    Its compact design makes it easier to install in confined spaces, while the motor is designed to provide efficient water removal.

    The pump also features mounting points for secure installation.

    For marine use, electrical connections should be properly sealed and positioned above the highest expected water level wherever possible.

    Easy Installation & Maintenance

    Installing the 12V Automatic Bilge Pump is straightforward when connected to a suitable power supply and discharge hose.

    For best performance:

    • Position the pump where water naturally collects.

    • Secure the pump using the provided mounting positions.

    • Connect a suitable 25 mm discharge hose.

    • Keep the inlet clear of debris and obstructions.

    • Use a correctly rated 12V DC power supply.

    • Protect electrical connections against moisture and corrosion.

    • Inspect and clean the pump regularly to maintain efficient water flow.

    Regular maintenance helps prevent blockages and keeps the automatic water detection system working as intended.

    Important Operating Information

    • 12V DC Supply Required: Use a suitable low-voltage power source capable of supplying the pump's electrical requirements.

    • Solar Operation: A compatible solar panel, charge controller and battery may be required to provide a stable power supply.

    • Maximum Flow: The 4,100 L/h rating is the maximum flow under ideal conditions. Actual performance decreases as pumping height and pipe resistance increase.

    • Maximum Head: The 4-metre rating represents the maximum pumping head, not the height at which maximum flow is delivered.

    • Correct Hose Size: Use suitable tubing compatible with the 25 mm outlet.

    • Electrical Safety: Ensure all wiring is correctly protected, insulated and secured.

    • Marine Installation: Position electrical connections above the highest expected water level and use appropriate waterproof sealing methods.

    • Prevent Blockages: Keep the pump inlet clear of debris and inspect it regularly.

    • Automatic Operation: Test the water detection function regularly to ensure the pump activates correctly.

    • Avoid Dry Running: Do not operate the pump without water beyond what is permitted by the manufacturer.

    • Installation: Follow the manufacturer's instructions for safe operation.

    With its automatic water detection, 4,100 L/h maximum flow rate and compact 12V design, this bilge pump is a practical solution for boats, marine applications and other suitable water drainage systems.
