AULINK Raw Sea Water Pump for Volvo Penta 21212799 – NSK Bearing, Stainless 304 Bolt, Includes Gaskets

AULINK 21212799 is a direct-fit raw seawater pump built to replace Volvo Penta units, featuring an original impeller, NSK bearing, and stainless 304 bolt for reliable cooling circulation.

This replacement seawater pump is engineered to match Volvo Penta specifications (OEM 21212799 / 3812519) and arrives with the gaskets and seals required for a straightforward swap. Built in TS16949-certified facilities and fully function- and leakage-tested, the unit focuses on long-term serviceability through premium internals—most notably a branded NSK bearing and corrosion-resistant hardware.

How does this pump match Volvo Penta originals?

The AULINK pump is manufactured to the same OEM reference numbers (21212799 and 3812519) and is sized to the factory mounting pattern and flow characteristics. That means bolt holes, shaft fit, and hydraulic performance are intended to align with Volvo Penta requirements for easier installation and predictable cooling behavior.

• OEM part compatibility: 21212799 / 3812519
• Factory-style mounting and shaft dimensions
• Preinstalled gaskets and seals for a precise fit

What components improve durability and performance?

Durability is driven by an original-style impeller for proper water handling, an NSK bearing for reduced wear, and a stainless 304 fastener to resist seawater corrosion. The combination reduces premature failure modes common in low-quality aftermarket pumps and keeps the circulating system running smoothly.

• NSK bearing reduces shaft play and extends service life
• Original impeller maintains designed flow and pressure
• Stainless 304 bolt resists rust in saltwater environments

Is installation and quality assurance handled by the manufacturer?

AULINK units are produced in TS16949-certified facilities and undergo 100% functional and leakage testing before shipment. The pump ships with gaskets and seals to simplify installation and minimize the need to source additional parts during replacement.

• TS16949 manufacturing standard for automotive-grade control
• Every pump leak-and-function tested prior to dispatch
• Includes all necessary gaskets and seals for installation

What sort of service support and limits apply?

The product includes a standard service support period of one year or up to 50,000 km of equipment use, whichever the installer or vessel owner specifies. This support window provides a clear timeframe for warranty or service inquiries without implying performance beyond normal operating conditions.

• One-year limited service support
• Coverage up to 50,000 km of service usage
• Support helps address fitment or manufacturing concerns

Who is this for: The AULINK 21212799 raw seawater pump is intended for boat owners, mechanics, and marine service shops replacing Volvo Penta seawater pumps or upgrading to a component with known-brand internals. It's suited to vessels that require OEM-number compliance, robust corrosion resistance, and a plug-and-play replacement that comes with the gaskets and seals needed to complete the job.
