Water boat pumps, or marine pumps, are specialized devices designed to move water in and out of boats or ships. They are essential for bilge pumping, ballast transfer, and firefighting on vessels. These pumps are built to withstand harsh marine environments and ensure reliable operation.

Size: Typically ranges from 1.5" to 12" in diameter, depending on the model and application.

Grade: Marine-grade pumps designed for saltwater and freshwater environments.

Viscosity: Suitable for fluids with viscosities up to 1,000 cSt (centistokes).

Buoyancy: Some models include buoyant materials for flotation in emergency scenarios.

Material: Constructed from corrosion-resistant materials like bronze, stainless steel, or reinforced plastics.

Flow Rate: Varies from 50 GPM to over 1,000 GPM, depending on pump size and power.

Pressure Rating: Typically operates between 50 PSI to 200 PSI.

Power Source: Electric, hydraulic, or engine-driven options available.

Temperature Range: Can handle fluids from -20°C to 120°C (-4°F to 248°F).

Seal Type: Mechanical seals or lip seals, often with abrasion-resistant coatings.

Mounting: Can be deck-mounted, inline, or submersible, depending on the design.
