Graco ProX19 Cordless Cart Sprayer ProXChange Pump Parts

Graco ProX19 Cordless Cart Sprayer — ProXChange Pump–Section Parts

Built around Graco’s field-proven ProX platform, the cordless ProX19 cart sprayer delivers 3,000 psi performance anywhere the job takes you—no cords, no generators. When the fluid section finally shows its hours, the Graco 24Y472 ProXChange Pump drops in tool-free so you can finish the project instead of the day. But the pump is only part of the story; the page you’re on stocks every OEM component you need to keep that replacement pump running like new, from prime-side hardware to electronic pressure regulation.

Four High-Value Upgrades That Pay for Themselves

1. Graco 235014 Prime Drain Valve Spray Kit – Our top-ticket item on this parts list, the PTFE-seated valve eliminates drips during priming and withstands repeated chemical flushes better than the legacy 224806 design it supersedes.
2. Graco 24Y472 ProXChange Pump – Restore full flow in under five minutes; stainless piston and chromex rod spray unthinned coatings up to 0.019 tip size.
3. Graco 17J881 Pressure Control Kit (3000 psi) – Tightens dead-band, delivering a steadier fan pattern when rolling 50-ft hoses or heavier elastomerics through the pump.
4. Graco 17G447 Machined Pump Housing – Precision-bored aluminum block restores alignment between the crank and piston, extending seal life and cutting vibration.

Complete OEM Coverage—Beyond the “Big Four”

Alongside these premium components you’ll find check-ball kits, wave springs, O-rings, inlet strainers and electrical brackets—every part cross-referenced to its original diagram number so you can build a single, accurate cart instead of chasing multiple suppliers. Stocking genuine pieces keeps your UL/CSA listing intact and prevents premature wear that cheaper substitutes can introduce to the chrome rod and pump sleeve.

How the ProXChange System Slashes Downtime

Conventional pumps require wrenches, seal drivers and 60 minutes on the bench. With Graco’s cartridge approach you simply pull two retaining pins, slide out the exhausted assembly, snap in the 24Y472, and prime. Add the 17J881 board and you’ve performed a full fluid-section and electronic refresh in the time it normally takes to lay out drop cloths.
