The Titan Epic series on this site covers five electric models (440E, 447EX, 447HPX, 660EX, 660HPX) and three gas models (690GX, 690HPG, 1200HPG). Titan's manuals list 3200 psi for the 660HPX, 447HPX and 690HPG, and 3000 psi for the 660EX. Each model has its own diagram pages for motor, gear box, fluid section, filter block, syphon and frame.
The Epic series in one paragraph
Epic is an older Titan piston-pump series, sold as electric and as gas models. The sprayers are no longer the newest Titan line, but their parts and manuals are still available, so there is no need to treat an Epic as a dead end. Two lookalikes cause most of the wrong orders. The ED655 is a diaphragm pump with no piston packings, and the Advantage and EPX series is a separate family with its own diagrams. If the label on your sprayer says Epic, stay on the Epic pages below. If it says anything else, start from that model instead.
Electric Epic models on the site
The five electric models sit together under Titan Epic Sprayer parts: the 440E, 447EX, 447HPX, 660EX and 660HPX. Titan's owner's manuals give a maximum working pressure for three of them. The 660HPX and 447HPX are both listed at 3200 psi, and the 660EX at 3000 psi. We do not have a verified pressure figure for the 440E or the 447EX, so check the label or the manual for those two.
The 447HPX and the 660HPX come in 120V and 230V versions, and the site has a separate electrical schematic page for the 230 volt motors on each. If you have a 230V unit, that page is where the electrical parts are listed.
Epic electric models and the pressure Titan's manuals list
| Model | Pressure listed by Titan | Frames on the site |
|---|---|---|
| 440E | Not verified here | Skid, low rider |
| 447EX | Not verified here | Frame assembly page |
| 447HPX | 3200 psi | Skid, low rider, high rider |
| 660EX | 3000 psi | Skid, low rider, stand-up |
| 660HPX | 3200 psi | Skid, low rider, high rider |
Pressure is Titan's stated maximum working pressure. Never run hose, gun or tip below the rating of the lowest component in the system.
Gas Epic models on the site
The gas models are the 690GX, 690HPG and 1200HPG, grouped under Epic Gas sprayer parts. Titan's manual lists the 690HPG at 3200 psi. We have no verified pressure for the 690GX or the 1200HPG, so confirm from the manual. The model letters (EX, HPX, GX, HPG) are Titan's own naming, and we do not guess what each suffix stands for. Match on the full model name printed on the sprayer instead.
Gas models swap the electric motor pages for engine pages. The 1200HPG has its own engine parts page, a frame page and a manifold and filter page. The 690GX lists a combined motor and filter housing page alongside its gear box and fluid section.
How each Epic diagram is organized
Every Epic model is split the same way, which makes the diagrams quick to navigate once you know the pattern. Pick your model, then pick the assembly that matches the problem.
Epic assembly pages and what each one holds
| Page type | What it covers | Examples from the 660HPX pages |
|---|---|---|
| Fluid section | The pump end: piston guide, packings, seals, inlet valve ball and foot valve seat | 700-587, 700-603A, 700-601A, 762-145, 762-137 |
| Gear box | Gearing, pressure control and electrical switches | 730-167A output gear assembly, 700-771 pressure control knob |
| Filter block | Manifold filter and the PrimeSpray valve | 730-067 manifold filter, 700-258 PrimeSpray valve assembly |
| Syphon assembly | Suction and bypass hoses, screens and the inlet valve housing | 700-206 siphon tube and hose, 730-511 inlet valve housing |
| Unitec motor complete | The motor page (the electric models) | 700-681 motor mount screw |
| Frame pages | Skid, low rider, high rider or stand-up frame, depending on model | 700-674 end cap, 0509550 cap screw (skid frame) |
| Accessories | Hoses, gauge, swivels, Piston Lube | 700-926 Piston Lube |
Page names vary a little between models, for example the 660HPX uses the spelling Syphon and the 690GX uses Siphon. Same idea, same place in the list.
Parts that recur across Epic models
Several fluid section parts show up on more than one Epic page. That is useful for knowing what to look for, but it is not permission to skip the diagram, because each model has its own page and its own list. Parts such as the 700-587 upper piston guide, the 700-601A lower seal assembly and the 700-603A upper packing assembly are on the 660HPX fluid section page. The 447HPX and 690HPG pages list the same piston guide and lower seal assembly, and the 690HPG page lists the same upper packing assembly as the 660HPX.
Epic fluid section and filter block parts you will see most
Titan states that the Epic fluid section design gives access to the inlet and outlet valves and seat without taking the unit completely apart. That is Titan's design statement, not a repair procedure. For the actual steps, and for what to inspect, use the manual for your model on our manuals page.
660HPX or 447HPX: which page is yours
These two get confused because both are electric, both are listed at 3200 psi, and both come in 120V and 230V. The practical difference for ordering is that they have separate diagrams. The 660HPX fluid section page lists 32 parts and the 447HPX page lists 38, so the two pump ends are not laid out the same way. The gear box pages differ in size too, at 21 parts for the 660HPX and 18 for the 447HPX. Order from the page that matches the name on your label, and do not carry a part number across from the other model without checking it on your own diagram.
Ordering without guessing
Read the model name off the sprayer
The label gives the full name, such as 660HPX, and the serial number. The suffix matters because 660EX and 660HPX have different diagrams.
Choose electric or gas
Electric models are under Titan Epic Sprayer parts and gas models under Epic Gas sprayer parts.
Open the assembly that matches the symptom
Leaking at the pump end or a pump that will not hold pressure belongs on the fluid section page. A blocked filter or a valve problem belongs on the filter block. Pressure control and switches are on the gear box.
Match the numbered callout to your part
Add the part from the numbered callout. If the page does not settle it, call (713) 931-0006 with the model and serial number.

The Short Version
Read the model name off the label, pick electric or gas, and open that model's own fluid section, filter block or gear box page. Do not take a part number from a different Epic model's page without checking it on yours.
