246428 Airless Spray Pump for Ultra Max II 390 395 490 495 595

In this review of the 246428 Airless Spray Pump the verdict is straightforward: this replacement pump is aimed at professional painters and serious DIYers who need a durable, cost-effective alternative to OEM pumps. The reviewer found it best suited for Graco Nova, Ultra and Max II series sprayers including 390, 395, 490, 495, 595 and LineLazer 3400 machines, delivering consistent displacement and reliable performance. The biggest reason to buy is the stainless steel construction and aftermarket 7900 piston pump displacement that offers longevity and a budget-friendly upgrade without sacrificing performance.

Key Features

• Compatibility: Designed to fit Graco Nova, Ultra and Max II series sprayers including 390, 395, 490, 495, 595 and LineLazer 3400 so users can expect correct fit for those models.
• Material: Constructed from stainless steel for improved durability and corrosion resistance compared with lower grade materials.
• Aftermarket Piston Displacement: Uses a 7900 piston pump displacement and 246428 designation to match expected fluid delivery and maintain spray consistency.
• Complete Kit: All necessary parts are included inside the pump housing which simplifies installation when performed by a professional technician.
• Performance Tested: Each pump is hydraulically tested prior to shipping which helps ensure the unit arrives working and ready for service.
• Cost Effective: Positioned as a more economical option than premium endurance pumps while maintaining acceptable service life for frequent use.

Who It's For

This pump is for contractors, rental shops and experienced DIY painters who already own compatible Graco Nova, Ultra or Max II sprayers and need a straightforward replacement that balances cost and durability. Its stainless steel build and tested displacement make it suitable for regular jobsite use where uptime matters.

It is not recommended for owners of ST Max models or anyone with an incompatible sprayer; the listing expressly warns DO NOT fit ST Max 390/395/490/495/595. Also, buyers who prefer factory-branded OEM parts or who require warranty-backed installation support should look at manufacturer options instead.
