Marine tank spray pumps are specialized systems designed for efficient liquid transfer and spraying in marine environments. These pumps are built to withstand harsh conditions, including saltwater corrosion and high-pressure applications. They are commonly used for cleaning, maintenance, and firefighting on ships and offshore platforms.

Size: Typically ranges from 1.5" to 6" discharge ports, with flow rates from 50 GPM to 1,500 GPM.

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

Viscosity: Suitable for fluids with viscosities up to 1,000 cSt, depending on pump type (centrifugal, diaphragm, or gear).

Buoyancy: Some models feature buoyant materials or flotation devices for overboard operations.

Material: Constructed from stainless steel (316L), aluminum, or reinforced thermoplastics for seawater resistance.

Pressure Rating: Operating pressures between 50 PSI to 300 PSI, depending on application.

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

Temperature Range: -20°F to 180°F (-29°C to 82°C) for standard models.

Seals: Mechanical seals or lip seals, often Viton or PTFE for chemical resistance.

Weight: Varies from 20 lbs (portable) to 500 lbs (fixed systems).
