Titan builds the Hydra X for roofing and protective coatings, thermal barrier and architectural coatings, waterproofing, epoxies and mastics. It names asphalt emulsion and acrylic roof coatings for the 4540, and harder-to-atomize materials such as silicone roof coatings for the 7230. Always check the coating maker's data sheet before spraying a given material.
What Titan builds the Hydra X for
Titan's own description of the Hydra X series is a gas-powered hydraulic airless sprayer for roofing, waterproofing and protective coatings, thermal barrier and architectural coatings, epoxies and mastics, on large commercial and industrial projects. That is the manufacturer's list, and it is the one to start from. It is not a promise that any particular product will spray: every coating has its own viscosity, solids content and application rules, and the coating maker's data sheet has the last word on tip size and method.
Three features explain why these coatings suit this sprayer. The hydraulic motor is what Titan calls HydraStroke, which Titan says handles heavy and light bodied coatings without burning out clutches. The fluid section is the Severe Service design, a long, slow-stroking piston with a tri-chrome coating that resists corrosion and abrasion. And direct immersion with the electric AutoLift means the pump goes into the container, so no transfer pump is needed.
Coatings Titan names for the Hydra X
| Coating | Named for | Where Titan says it |

| Asphalt emulsion | Hydra X 4540 | Titan's launch announcement |
| Acrylic roof coatings | Hydra X 4540 | Titan's launch announcement |
| Silicone roof coatings | Hydra X 7230 (harder-to-atomize materials) | Titan's launch announcement |

This is Titan's list, not a complete list of what the sprayer can handle. If your coating is not named, ask the coating maker and our parts team before you commit a job to it.
4540: heavy coatings
Titan's launch announcement positions the Hydra X 4540 for heavy coatings, naming asphalt emulsion and acrylic roof coatings. Its maximum pressure is 4500 psi and it supports up to six guns, which matters to crews that run several guns on one roof. Its fluid section is the one on the Hydra X (4540) Fluid Section page.
The Titan pages we reviewed for the Hydra X do not name elastomerics, block fillers or fireproofing, so we do not claim them. If your material is one of those, ask the coating maker whether a Hydra X is an approved sprayer, and call us at (713) 931-0006 with your model so we can look at the configuration you own.
7230: harder-to-atomize coatings
The Hydra X 7230 reaches 7250 psi. Titan describes it for harder-to-atomize materials such as silicone roof coatings, which is the clearest case of a model choice being driven by the coating. Titan's pairing points to pressure as the reason: the 7230 trades some delivery for it, and supports up to five guns instead of six. The 7230's wear parts are on the Hydra X (7230) Fluid Section page and carry different part numbers from the 4540's.
Both models can be converted. The site sells 02424618 for the 4540 to 7230 and 2432905 for the 7230 to 4540. Titan describes the fluid section as modular, supporting two performance levels. We do not describe what a conversion involves, because Titan's procedure is not something to guess; use the manual or call us.
Tip size and guns for thick material
Thick coatings call for large orifices, and the more guns you run, the smaller each tip has to be, because the pump's delivery is shared between them. Titan's table shows that clearly on the 4540: 0.067 in. is the maximum tip with one gun and 0.029 in. with five. On the 7230 the 2-gun maximum is 0.035 in. and the 5-gun maximum is 0.021 in. For other gun counts, take the figure for your model from the manual.
- Choose the tip for the coating first, then count the guns it will allow. A heavy coating at several guns may not fit the tip you want.
- Strain and stir the coating, and thin only as the coating maker allows.
- A worn tip has a wider orifice, so pressure falls and the pattern gets coarse. Keep spare tip seats and seals on the truck: 661-020.
- Use a gun and hose rated at or above your sprayer's maximum, such as 0538070, and check its rating on the product page.
For multiple guns, the manual says to connect a manifold kit to the single gun outlet and plug the unused outlets. Keep the gun 10-12 in. (25 to 30 cm) from the surface and never spray without the tip guard.
Prepare the sprayer for each coating
Flush a new unit first
A new Hydra X ships with test fluid. The manual says to flush it with mineral spirits before first use.
Check the fluid already in the system
The manual says to make sure that what is in the system is compatible with the paint you are about to run.
Strain the coating
The manual has you strain paint through nylon strainers. Chunks and skins are what block the suction screen and the gun filter.
Set up the lines
The manual requires at least 50 ft of nylon airless spray hose to be attached. Ground the sprayer, and keep it outside the immediate spray area when you spray flammable material.
Know your clock
Fast-drying and two-component coatings must be rinsed within their processing time, which the coating maker sets. Plan the day so the sprayer can be flushed in time.
Our manuals page has the Hydra X manual with the exact procedures. Pressure relief comes before any maintenance or tip change: lock the gun, relieve pressure as your manual describes, and never put a hand or finger over the tip, since fluid at spray pressure can inject through the skin.
Wear to expect and the parts to stock
Heavy and aggressive coatings are hard on the fluid section, which is why Titan builds it with a tri-chrome coating and self-adjusting packing. Titan does not publish a service life for the packings or other fluid section parts, so we cannot give hours or gallons, and any life depends on the coating and the pressure. Watch for the symptoms instead: lost pressure, pulsing, or a pump that moves but does not deliver.
- 4540: 0533651 V-Packing, 0533683 Inlet Ball Seat, balls 315-700 and 211-129, listed on the 4540 fluid section page.
- 7230: 0533663 V-packing PTFE, 0533694 Ball Seat and 51519 Inlet Ball, listed on the 7230 fluid section page.
- Both: 314-480 Piston Lube for the daily packing oil fill, and 0089957 gun filters.

The Short Version
Titan names asphalt emulsion and acrylic roof coatings for the 4540 and silicone roof coatings for the 7230, and lists roofing, waterproofing, protective, thermal barrier and architectural coatings, epoxies and mastics for the series. Treat that list as a starting point, confirm each material with its maker, flush and strain properly, and keep spare tips, filters and Piston Lube close by.
