Marine generator coolant pumps circulate coolant to maintain optimal engine temperatures. These pumps are integral to the cooling system, preventing overheating and ensuring efficient operation. They are designed for durability and reliability in harsh marine environments.

Size: Typically ranges from 50 mm to 300 mm in diameter, depending on the engine size and cooling requirements.

Grade: Industrial-grade, marine-grade compliant with ISO 8846 and SAE J1171 standards.

Viscosity: Compatible with coolants having viscosities between 5-50 cSt at operating temperatures.

Buoyancy: Designed to maintain neutral buoyancy in seawater or freshwater environments.

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

Flow Rate: Typically 20-500 GPM (gallons per minute) depending on system requirements.

Pressure Rating: Operates at 10-100 PSI, with high-pressure variants available for specific applications.

Temperature Range: -40°C to 120°C (-40°F to 250°F) for standard models.

Seal Type: Mechanical seals or lip seals, often made from carbon-ceramic or Viton for durability.

Power Source: Electric (12V/24V/110V/220V) or engine-driven, depending on the system design.

Mounting: Flange-mounted or direct-coupled to the engine cooling system.

Impeller Type: Closed or semi-open impeller designs for efficient fluid movement.

Compatibility: Works with ethylene glycol or propylene glycol-based coolants.

Certifications: Meets ABS, DNV, and Lloyds Register standards for marine applications.

Yes, Marine Generator Coolant Pumps and Cooling Systems typically comply with maritime standards such as ISO 8846, SOLAS, and ABS/Class Society requirements.
