ANJIESENG Pressure Washer Pump – 4400PSI 4.8GPM

The ANJIESENG Pressure Washer Pump is a premium OEM-grade replacement designed to restore peak performance to your gas-powered pressure washer. Crafted from solid brass and featuring a 1-inch shaft horizontal triplex plunger, this pump delivers a robust 4400PSI and 4.8 GPM flow rate, ideal for residential and light commercial cleaning tasks. For optimal longevity, ANJIESENG recommends operating at 3400PSI @ 3400 RPM—a balance that maximises efficiency while minimising wear.

Built with durability in mind, the pump incorporates a fully anodised black crankcase and a reinforced brass pump head, ensuring resilience against heavy use. Its triplex design reduces vibration and enhances smooth operation, while the integrated sight glass and advanced oil seal technology eliminate the need for a traditional dipstick, simplifying maintenance. The adjustable unloader valve allows users to fine-tune pressure output, making it versatile for tasks ranging from driveway cleaning to vehicle washing.

Compatibility is a key feature, with this pump designed to fit most 9–15HP engines or 270–420cc models, including popular brands like Honda GX340/GX390, Generac, Briggs & Stratton, and Simpson. Installation is straightforward, thanks to industry-standard SAE mounting dimensions, including a 1″ shaft hole and a 6½″ diagonal hole distance. ANJIESENG backs the product with a 1-year limited warranty and offers prompt customer support within 12 hours of any enquiry. Note: This pump is for cold water use only.
