Marine sump pumps are specialized pumps designed to remove accumulated water from bilges and other low-lying areas on boats and ships. These pump systems are built to withstand harsh marine environments, including saltwater corrosion and continuous operation. They ensure vessel safety by preventing flooding and maintaining proper water levels.

Size: Typically ranges from 1.5" to 12" discharge diameters, with flow rates from 50 GPM to over 5000 GPM.

Grade: Marine-grade construction, often compliant with ABS, DNV, or other maritime standards.

Viscosity: Suitable for fluids with viscosities up to 1000 cSt, depending on pump type.

Buoyancy: Designed to handle bilge water, oil, or other marine fluids; some models include float switches for automatic operation.

Material: Constructed from corrosion-resistant materials like bronze, stainless steel (316L), or reinforced thermoplastics.

Power: Electric or hydraulic-driven, with voltage options ranging from 12V DC to 480V AC.

Pressure: Operating pressures typically between 10 PSI to 150 PSI, depending on application.

Temperature Range: -20°C to 120°C, varying by material and seal type.

Seals: Mechanical seals or lip seals, often oil-resistant for hydrocarbon handling.

Mounting: Vertical or horizontal configurations, with options for submersible or dry-installation.
