Marine engine operators know: a failed seawater pump means immediate overheating, unplanned downtime, and costly repairs — especially on vessels operating in warm coastal or tropical waters. OEM replacements often take 2–4 weeks to arrive, while low-cost alternatives fail within 300 operating hours due to inferior impeller materials and inconsistent clearances. With aging fleets across North America, Europe and Southeast Asia, getting the right part — fast and verified — is no longer optional.
This Volvo Penta seawater pump meets original performance specifications for flow rate, pressure head, and thermal tolerance — validated through pre-shipment bench testing at our ISO-certified partner factory. Built for real-world use in excavator support boats, dredging barges, and marine construction vessels, it delivers reliable cooling during continuous operation under high ambient temperatures. As a professional supplier serving 120+ countries for 10 years, we stock over 10,000 heavy equipment parts — including this seawater pump — ready for same-day dispatch when ordered before 3 PM CST.
This seawater pump operates continuously in saltwater environments aboard workboats, tugboats, and marine auxiliary systems supporting port infrastructure, offshore wind installation, and coastal demolition projects. It withstands abrasive particulates, biofouling, and thermal cycling — critical where coolant flow interruption risks engine seizure within minutes. Whether installed on a 4.3GXi-JF used in inland waterway dredging or a V8-320-CE-B powering a floating crane at Dubai Port, correct specification ensures system integrity under sustained load.
The pump housing is precision-cast from marine-grade aluminum alloy (A380), offering superior corrosion resistance and dimensional stability versus standard A360. The impeller uses NBR rubber vanes bonded to a stainless steel hub — proven to retain shape and pumping efficiency after 1,200+ hours in 3.5% salinity water. Shaft runout is held to ≤0.05 mm per ISO 21940-11, preventing premature bearing wear. All gasket surfaces are CNC-machined to ±0.02 mm flatness, ensuring leak-free sealing without excessive torque. Surface finish on the inlet/outlet ports complies with ISO 1302 Ra 3.2 μm, minimizing flow turbulence and cavitation risk.
A $45 counterfeit seawater pump may save upfront, but causes catastrophic failure within 200 hours — leading to $2,800 in engine rebuild labor, $1,600 in cylinder head damage, and $12,000+ in vessel idle time per day. Genuine OEM parts carry long lead times and cost 35–50% more than this XUNPO aftermarket solution. Our pump meets Volvo Penta’s original flow curve (12.5 L/min at 3,200 rpm) and pressure specs (0.8 bar at full load), reducing total cost of ownership (TCO) by up to 42% over 3-year service life — verified by field data from 27 repair centers across Florida, Greece, and Singapore.
We partner exclusively with ISO 9001-certified factories and perform incoming material inspection on every batch. Each seawater pump undergoes functional testing at rated speed, temperature, and salinity before shipment. We offer 3–12 month warranty covering all manufacturing defects — no questions asked. With 10 years of export experience and verified shipments to 120+ countries, our technical team has confirmed over 42,000 part matches since 2016. You’ll receive accurate compatibility verification within 2 hours of inquiry. And because we hold 10,000+ SKUs in our Guangzhou warehouse, your order ships in 2–5 working days — no waiting for production runs or overseas consolidation.
Your vessel’s cooling system can’t wait — every hour of downtime costs revenue, reputation, and contractual penalties. Send us your engine model (e.g., 5.7GXiE-320-R), quantity, and destination port — we’ll reply with a competitive quote within 24 hours. First-time buyers may request a sample for physical verification before bulk order. Stock is limited; orders placed before 3 PM CST ship the same day.

A: Provide your exact engine model (e.g., 4.3GXi-JF or V8-320-E-B) and we’ll verify compatibility using our technical database — response guaranteed within 2 hours.
Q: What is the warranty period?
A: 3–12 months against manufacturing defects. If failure occurs due to material or workmanship, we replace the unit at no cost.
Q: What is the minimum order quantity?
A: 1 piece — no exceptions. Ideal for emergency repairs or validation testing.
Q: How fast can you ship?
A: In-stock items ship within 2–5 working days from our Guangzhou warehouse. Express options available for urgent deliveries.
Q: Can I receive a sample before placing a bulk order?
