A boat bailing pump is a manual or electric device used to remove water from vessels to prevent flooding. Marine pumps are essential for maintaining buoyancy and safety by efficiently draining excess water. They come in various types, including bilge pumps, designed for different boat sizes and conditions.

Size: Typically ranges from 12V to 24V models, with diameters of 2-4 inches and lengths of 6-12 inches.

Grade: Marine-grade construction, often meeting ISO 8846 and ABYC standards.

Viscosity: Suitable for fluids with viscosities up to 200 cSt (centistokes).

Buoyancy: Designed to remain operational even when partially submerged, with buoyant materials in some models.

Material: Corrosion-resistant materials such as stainless steel, aluminum, or reinforced plastics like ABS or polypropylene.

Flow Rate: Typically 500-5,000 gallons per hour (GPH), depending on model and power source.

Power Source: Electric (12V/24V DC), manual, or engine-driven options.

Pressure Rating: Operates at low to moderate pressures, usually under 50 PSI.

Temperature Range: -20°C to 80°C (-4°F to 176°F) for standard models.

Weight: Varies from 1-10 lbs, depending on size and material.

Hose Compatibility: Fits standard marine hoses with diameters of 1-2 inches.

Seal Type: Often includes neoprene or nitrile seals for water resistance.

Mounting: Can be deck-mounted, bilge-mounted, or portable, depending on design.
