Tsunami Bilge Pump - 500 GPH--Tsunami pumps are durable and designed to last. Our efficient design circulates water around the pump motor housing, helping to absorb the heat given off by the operating motor. We use the most advanced material available, including the best quality bearings and state-of-the-art brushes, alloys and magnets. Our patented shaft seal centers directly on the motor shaft, preventing leaks caused by misalignment. Our exclusive molded two-wire seal is permanently fused to the insulation to prevent a leak path and our wiring is caulked and tinned to eliminate wicking, prevent water damage and resist corrosion.The bilge pump is secured directly to the hull—no bracket required. • No brackets required• Cooler-running motors, premium materials, watertight seals and waterproof wiring• One-hand access• Cartridges are replaceable and interchangeableTsunami pumps are durable and designed to last.
