Ocean Tech Heavy-Duty 2250gph Bilge Pump

The Ocean Tech Heavy-Duty 2250gph Bilge Pump is built to protect larger vessels from everyday hull leaks and unexpected water ingress. This new heavy‑duty marine submersible pump delivers serious pumping power in a compact, reliable package designed to withstand harsh offshore conditions. Ideal for pleasure boats and commercial craft over 12 meters (36 feet), it keeps bilges dry so you can stay focused on the voyage ahead.

Key features that matter on the water

• with a liquid-cooled motor for extended life and consistent performance in challenging environments.
• up to 2250 GPH (140 L/min) under optimal conditions, and 1900 GPH (120 L/min) at a 1 m head, ensuring rapid water removal when you need it most.
• includes an AISI 316 stainless steel shaft, double ball bearings, and a mechanical seal, all housed in a tough thermoplastic ABS enclosure for marine resilience.
• with a strainer and a T-slot pin to attach an optional level switch for automatic operation, reducing the need for manual monitoring in rough seas or during extended passages.
• to prevent backflow and maintain reliable priming, simplifying installation and maintenance.
• optimized for continuous duty on commercial or private vessels, delivering dependable performance voyage after voyage.
• suitable for boats over 12 m (36 ft) in length, making it a practical upgrade for larger hulls where bilge management matters.
• shipped from local New Zealand suppliers, with the product code 31186 for easy reference and support.

Why this bilge pump stands out

Where many bilge pumps rely on lighter builds or cheaper components, the Ocean Tech Heavy-Duty 2250gph Bilge Pump combines a corrosion-resistant ABS housing with a durable AISI 316 shaft and precision bearings. The result is a marine pump that resists galvanic corrosion, maintains peak efficiency under load, and tolerates continuous operation in damp, salt‑spray environments. The optional level switch capability via the base plate means you can automate bilge response—ideal for long passages, remote docks, or commercial operations where hands-free monitoring matters.

Ideal use scenarios

• Storm-surge or heavy rain scenarios where rapid bilge evacuation is critical to maintain buoyancy and stability.
• Vessels operating in remote locations where reliable, automatic bilge management reduces crew fatigue and risk.
• Commercial craft and pleasure boats above 12 meters needing a robust, long‑life bilge solution with easy maintenance.

Practical installation and care tips

• Mount the pump to the universal base plate and connect the strainer to ensure debris capture without impeding flow.
• Use the included check valve to prevent backflow when the pump cycles off.
• If automatic bilge control is desired, pair the base plate with a compatible level switch adapter (not included) for hands-free operation.
• Keep the power connections clean and dry, and inspect the mechanical seal and bearings during routine maintenance intervals.
• Verify electrical compatibility and ensure the 12V supply can handle peak current draw during high‑flow conditions.

Built by Ocean Tech to meet demanding marine needs, the Heavy-Duty 2250gph Bilge Pump offers confidence, longevity, and practical value for skippers who expect more from their bilge management gear. Whether you’re upgrading an aging system or outfitting a new build, this pump delivers the performance you can rely on when every drop counts.
