Engineered for precision and durability, this oil pump is manufactured to OEM-equivalent standards, ensuring flawless compatibility and performance. It guarantees optimal engine lubrication by maintaining consistent oil pressure within a critical range of 35-85 PSI, directly impacting engine longevity and efficiency. Crafted from high-grade alloys, its internal components are rigorously tested to minimize wear and deliver a service life exceeding 100,000 kilometers under normal operating conditions.
The pump's efficient design ensures a high-volume flow rate of 4.2+ GPM, providing immediate lubrication upon engine start and superior protection at high RPMs. Each unit undergoes stringent quality control, including pressure and flow bench testing, to verify 100% performance compliance. This is a direct-fit, reliable solution engineered to restore and maintain your engine's vital circulatory system, safeguarding against premature wear and costly repairs.
Our oil pump is constructed from high-strength cast iron and hardened steel gears, providing superior resistance to heat and wear. The rotors are machined to tolerances within ±0.01mm, ensuring a perfect fit and eliminating internal slippage. This meticulous engineering minimizes parasitic power loss and guarantees consistent performance, contributing to a service life that exceeds 100,000 miles. This durability directly translates to long-term engine health and prevents premature component failure.
We ensure 100% compliance with original equipment specifications. Every pump undergoes a stringent 12-point quality check, including a 5-hour continuous endurance test under extreme pressure conditions. Our failure rate is a mere 0.2%, a testament to our manufacturing excellence. This commitment to OEM-equivalent quality means you get a part that fits perfectly and performs reliably, without the high cost of a genuine dealer part.
Engineered for efficiency, this pump delivers a consistent flow rate of 4.5 Gallons Per Minute (GPM) at standard operating pressure. Its advanced gerotor design ensures rapid oil delivery upon engine start-up, critically reducing dry-start friction by up to 40%. This immediate lubrication is vital for protecting turbochargers and main bearings, ensuring your engine is safeguarded from the moment you turn the key, especially under high-stress conditions.
Maintaining correct oil pressure is non-negotiable. This pump is calibrated to sustain a stable oil pressure between 35-85 PSI across the entire RPM range, preventing dangerous pressure drops. It is a direct-fit replacement, requiring no modifications for installation. This guarantees a hassle-free service experience, restores factory-level performance, and provides peace of mind against oil-related engine damage.
Critical internal components are treated with a proprietary phosphate coating that enhances surface hardness and provides exceptional resistance to corrosion and scuffing. This extra layer of protection ensures consistent performance even with varying oil grades and in extreme temperature environments, from -22°F to 300°F. This results in a more robust pump that maintains its efficiency over its entire lifespan.

Here are specific application scenarios of oil pump:
For optimal performance and engine safety, always prime the new oil pump with fresh engine oil before installation. This prevents dry starts and ensures immediate lubrication. Use a new gasket and strictly adhere to the manufacturer's specified torque sequence and values (typically 18-22 N·m for mounting bolts) to ensure a perfect seal. After installation and refilling with oil, crank the engine for 10-15 seconds without starting to build initial oil pressure. Finally, start the engine and verify stable oil pressure above 35 PSI at idle. Always consult a professional mechanic for installation.
