Marine tank drain pumps are specialized systems designed to efficiently remove water from ship tanks and bilges. These pumps are built to handle harsh marine environments, ensuring durability and reliable performance. They come in various types, including electric, hydraulic, and manual, to suit different vessel needs.

Size: Typically ranges from 1" to 12" in diameter, depending on application.

Grade: Marine-grade materials compliant with ASTM, ISO, or MIL-SPEC standards.

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

Buoyancy: Designed to be neutrally buoyant or positively buoyant in seawater.

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

Flow Rate: Varies from 50 GPM to 1,500 GPM, depending on pump size and power.

Pressure Rating: Typically 50 PSI to 300 PSI, based on system requirements.

Temperature Range: Operates between -20°F to 300°F (-29°C to 149°C).

Power Source: Electric (12V/24V/110V/220V), hydraulic, or pneumatic-driven options.

Seal Type: Mechanical seals or lip seals, often rated for submerged operation.

Weight: Varies from 10 lbs to 500 lbs, depending on size and material.

Certifications: Often meets ABS, DNV, or USCG standards for marine use.
