The 12000 Plus DI runs more guns and bigger tips. Titan lists it at up to six guns with a Honda GX270, against up to four guns and a GX160 on the 6900 Plus DI. Both share the submersible foot valve and EZ swing frame, but their fluid sections, belts and engine kits carry different part numbers.
Titan sells two DI sprayers in the PowrTwin Plus line, the 6900 Plus DI and the 12000 Plus DI. Both are described as built for very heavy materials, so the choice is mostly about how many guns you run and how big the tips must be. This page compares what the sources agree on. It leaves out the 6900's flow and pressure, because Titan's product pages and its owner's manuals give different numbers for them.
The short answer
6900 Plus DI and 12000 Plus DI at a glance
| 6900 Plus DI | 12000 Plus DI | |
|---|---|---|
| Guns Titan lists | Up to 4 | Up to 6 |
| Engine (Titan page) | Honda GX160 | Honda GX270 |
| Engine displacement (Plus manual) | 163 cc | 270 cc |
| Complete gas unit | 0290021 | 0290023 |
| Complete fluid section | 451-210 | 236-024 |
Titan's pages give the 12000 Plus DI a pressure control range of 400 to 3600 psi. We leave the 6900 Plus DI's flow and maximum pressure out because the sources conflict.
If you run one to four guns on medium-sized tips, the 6900 Plus DI is the smaller of the two and covers it. If you need five or six guns, or tips above what four guns allow on the 6900, the 12000 Plus DI is the model Titan lists for it.
Tip limits side by side
The maximum tip falls as you add guns, because the pump's delivery is shared between them. These are the limits Titan lists for the gas DI models:
Maximum tip by number of guns (Titan's product pages)
| Guns | 6900 Plus DI | 12000 Plus DI |
|---|---|---|
| 1 | 0.050 in. | Sources disagree |
| 2 | Sources disagree | 0.040 in. |
| 3 | 0.023 in. | 0.034 in. |
| 4 | 0.019 in. | 0.030 in. |
| 5 | Not listed (four guns maximum) | 0.026 in. |
Where the sources disagree we leave the cell blank on purpose. Never exceed the maximum tip for your gun count; your manual lists the limit for your model.
Set these beside the Plus manual's tip chart. Primers and commercial architectural coatings run 0.017 to 0.019 in., dry fall and one-coat paints 0.019 to 0.023 in., and elastomerics 0.021 to 0.031 in. A 6900 Plus DI on four guns tops out at 0.019 in., so it suits primers and house paints but is below the elastomeric range. The 12000 Plus DI on four guns allows 0.030 in. and on five 0.026 in.
What they share
- Titan describes both as having a submersed foot valve, built for very heavy materials including drywall mud. See the DI accessories and the fluid section pages below for the parts involved.
- Both have the EZ swing frame, which Titan says decreases spillage during paint changes and lowers the height and centre of gravity for transport.
- Both appear with the RX-Apex non-filter gun on the site's DI accessories diagrams.
- Both fluid sections use the minor service kit 144-050, and both have a heavy-materials bleed valve diagram.
Fluid sections: where the part numbers split
The two pumps share many fluid section parts, including repacking kit 138-153A, packing springs 142-004 and 142-003 and outlet valve ball 0509710. The parts that define each pump are different:
Parts that differ on the two DI fluid sections
| Part | 6900 Plus DI | 12000 Plus DI |
|---|---|---|
| Foot valve housing | 451-132 | 459-019A |
| Inlet screen | 451-018 | 710-046 |
| Rod and cylinder | Piston rod 451-131, cylinder 0349606 | Displacement rod 144-117, pump cylinder 144-832 |
| Major kit | 143-500 (per the DI manual) | 144-500 |
Check the diagram for your model before ordering. The 6900 Plus DI fluid section and 12000 Plus DI fluid section pages list every part.
The drive side also differs. The 6900 Plus DI main assembly lists belt 449-125 (A-40), while the 12000 Plus DI main assembly lists 0290510 (AX44) and also shows 449-181, a belt listed as 120V. The gas Convertokit engine kits are 980-331A for the 6900 Plus DI and 764-021A for the 12000 Plus DI. See the 6900 Plus DI main assembly and 12000 Plus DI main assembly.
Which one for which job
Count the guns
One to four guns fits either model. Five or six is the 12000 Plus DI only.
Check the tip you need
If your coating calls for a larger tip than the 6900 Plus DI allows at your gun count, move up to the 12000 Plus DI or run fewer guns.
Think about the engine
Titan lists a GX160 on the 6900 Plus DI and a GX270 on the 12000 Plus DI. Check your engine manual for its other specifications.
Confirm the model and serial
The parts above differ by model, so confirm yours before you order. Call (713) 931-0006 if the diagram is not conclusive.

The Short Version
Choose on guns and tip size. The 6900 Plus DI runs up to four guns, the 12000 Plus DI up to six with larger tips at each gun count. Both share the DI foot valve and frame, but foot valve housings, inlet screens, belts and engine kits have different numbers, so order from the diagram for your model.
