If you're looking for a rugged, high-volume graco airless paint sprayer to tackle heavy-duty job site demands, the Graco DutyMax GH230 HD Standard Series delivers powerful performance with a compact design. Powered by a 5.5 HP Honda engine and paired with Graco’s high-capacity fluid section, this sprayer requires precise components for reliable performance and ease of maintenance. At SprayersAndParts.com, we’ve organized a comprehensive graco parts list and diagram covering everything—from drive gears to gun parts and graco sprayer accessories—so you can serve your fleet efficiently using shared inventory like graco magnum x5 parts.

1. Engine & Drive Assembly

The engine-driven architecture of the DutyMax is built for endurance:

• Honda, 5.5 HP engine – The dependable four-stroke motor delivers consistent torque even in harsh conditions.

• Crankshaft & Bearings – Precision bearings and crank bolt (#15A080) ensure smooth rotational power transfer.

• Cooling Fan and Housing – Heavy-duty cooling assembly keeps engine vitals in check during prolonged operations.

• Mounting Hardware – Bolts, washers, and base plate parts are designed to absorb vibration without loosening.

These motor and drive components dovetail neatly with part families found in graco magnum x5 parts, aiding in flexible stock usage across different sprayer models.

2. High-Capacity Fluid Section & Pump

The pumping system is the heart of spraying capability:

• Displacement Pump – High-pressure fluid section rated up to 3,300 psi delivers coarse coatings or paint with professional control.

• Main Housing and Seals – Including head gasket (#241699) and manifold O-rings, these parts prevent leaks and maintain pressure.

• Stainless Chromex Pistons & V-Max Packings – Durable inside the fluid section, engineered to endure tough coatings and long shifts.

• Valve Seats, Balls & Springs – Wear items that can be replaced quickly using factory-rebuild paint sprayer parts kits.

This pump setup mirrors those used in the graco electric paint sprayer lineup and is serviceable using graco magnum x5 parts, consolidating maintenance resources.

3. Suction Hose & Filtration System

Clean fluid intake ensures consistent output and spray quality:

• Suction Tube fitting – Includes swivel joint and ¼″ NPT adapter for rapid breakdown and storage.

• 60/100 Mesh Filter Kits – Inline filters prevent debris from damaging pump seals and tips.

• Drain Hose & Deflector – Simplifies system cleanout at the end of the day, reducing coating waste and mess.

All these parts cross-apply to both gas and electric models and are essential graco sprayer accessories.

4. Spray Gun, Tip, & Accessory Kit

Delivering that professional finish begins at the spray tip:

• Contractor FTx Handgun/Cardemo series gun – Built for full 3,300 psi operation, compatible with multiple RAC-X tip sizes.

• Tip Guard & Tips (such as 517, 525 UVT) – Protect user and surfaces, while enabling fast tip cleanup using the liquid-back control.

• Inline filters and Quick-Connect Couplings – Keep material flow smooth and make gun change-outs faster during finishing jobs.

• Flexible Whip Hose – Connects gun to sprayer, allowing for agile movement without disturbing cart setup.

All gun and accessory parts are shared across graco airless paint sprayer models—inventory-friendly and ready for high-volume tasks.

5. Cart Frame, Wheels & Job-Site Hardware

Mobility and ruggedness are essential on job sites:

• DutyMax Compact Frame – Sturdy steel design with wheel brackets and spring-loaded support feet.

• 10″ Pneumatic Wheels (Part #119451) – Built to handle all types of terrain, from gravel to project bins.

• Sprayer Accessories – Includes hose clips, wand holders, paint can hangers, plus mounting bolts and chain kits to secure hoses during transport.

These mounting parts align with graco magnum x5 parts catalogs, making it easy to manage fleets of gas and electric units.

6. Control Box & Pressure Regulation

Precision control matters when spraying:

• Control Manifold Assembly – Features pressure regulator, valves, and gauge ports for flawless atomization.

• Pressure Transducer & Harness – Provides consistent pressure feedback and keeps the pump output steady.

• Flexible Supply & Drain Hoses – High-pressure media lines are built to resist wear, abrasions, and kinks.

The control components mirror those in electric GH230 variants, ensuring consistent part supply and service protocols.

7. Shared Parts Across Gas & Electric Fleets

Fleet operators appreciate the efficiency:

• Many fluid section seals, valves, hoses, and tips overlap with graco electric paint sprayer models (such as 695, 795, 395 Magnum).

• Pumps and control valves use a common rebuild protocol, simplifying technician workflows.

• Shared mounting accessories and electrical harness clips mean you can stock once, serve both gas and electric units.

8. Maintenance Plan & Build Kits

Maintain peak performance with a simple schedule:

• Daily: Flush and droplevel fluid section; inspect hoses and filters.

• Every 50 hours: Clean or replace intake filters; check suction joints.

• Every 200 hours: Replace O-rings and packings using graco sprayer parts kits.
