Marine Urea Dosing Pumps are specialized systems designed to accurately inject urea solution into marine exhaust streams for selective catalytic reduction (SCR). These pumps ensure precise dosing to reduce nitrogen oxide (NOx) emissions, complying with environmental regulations. They are built to withstand harsh marine conditions, offering reliability and durability.

Size: Typically ranges from compact units (10-20 cm) to larger systems (up to 100 cm) depending on application.

Grade: Designed for marine-grade urea solutions (AUS 40 or AUS 32) with high purity standards.

Viscosity: Optimized for urea solutions with viscosity similar to water (1-2 cP at 20°C).

Buoyancy: Not applicable as these are fixed or mounted systems; no floating requirements.

Material: Constructed from corrosion-resistant materials like stainless steel (316L), plastics (PTFE, PVDF), or specialized coatings.

Flow Rate: Adjustable, typically 5-5000 liters per hour depending on system size.

Pressure Range: Operates at 1-10 bar, with high-pressure variants for specific applications.

Temperature Range: -20°C to +80°C for standard models, with heated options for cold climates.

Power Supply: 12V/24V DC or 110V/230V AC, depending on marine electrical systems.

Certifications: Compliant with IMO Tier III, MARPOL Annex VI, and other marine emission standards.
