Step up if you run four guns. Titan lists the 4900 Plus at up to three guns and the 6900 Plus at up to four. Both are slow-stroking hydraulic piston sprayers, but their fluid sections use different part numbers, so never swap parts between them.
The 4900 Plus and 6900 Plus are the two smaller gas PowrTwin Plus models. They share the same design: a gas engine drives a hydraulic motor, and the motor strokes a piston fluid section. The question for a small crew is whether the bigger pump earns its place. This page answers it with the differences Titan's product pages and manuals agree on, and it leaves out the 6900 Plus's flow and maximum pressure because those sources conflict.
The short answer
4900 Plus and 6900 Plus compared
| 4900 Plus | 6900 Plus | |
|---|---|---|
| Guns Titan lists | Up to 3 | Up to 4 |
| Max tip, 3 guns | 0.022 in. | 0.023 in. |
| Max tip, 4 guns | Not applicable | 0.019 in. |
| Complete unit | 0290012 | 0290013 |
| Electric version flow | 1.10 gpm (4.2 L/min) | 1.25 gpm (4.7 L/min) |
Titan's sources conflict on the 4900's one- and two-gun tips and on its engine, and on the 6900's flow, pressure and two-gun tip, so those rows are omitted on purpose.
If you never run more than three guns, the extra headroom between the two is small: at three guns the maximum tips are 0.022 in. on the 4900 Plus and 0.023 in. on the 6900 Plus. The 6900 Plus is the one to choose when you run four guns, because the 4900 Plus does not list a fourth.
What both give you
Titan's pages list the same core features across the Plus models: a slow-stroking hydraulic piston, a vented hydraulic fill and dipstick, an easy-remove filter that takes three turns, a wrap-around frame and a cart with a telescoping handle. The 4900 Plus has a pressure control range of 400 to 3300 psi on Titan's page. Both are listed for primers through heavy-bodied finish paints, and for stains, lacquers, epoxies, enamels, elastomeric, latex, dry fall and block fillers. What changes between them is how many guns the pump can feed.
Electric versions
Both models come in electric form, and Titan's pages and manuals agree on the flow. The electric 4900 Plus is listed at 1.10 gpm and the electric 6900 Plus at 1.25 gpm. The electric 4900 Plus has maximum tips of 0.031 in. at one gun, 0.028 in. at two and 0.022 in. at three. Titan lists the electric 6900 Plus at up to two guns. If you need three guns on electric, the 4900 Plus electric lists it and the 6900 Plus electric does not.
The electric requirements are the same for both. The manuals call for a 20 amp service outlet, a short cord and a long paint hose, and only a grounded 3-wire #12 extension cord if you must use one. The complete electric 6900 Plus is 0290028 on the site; Titan lists 290032 for the 4900 Plus electric, but we could not find it on the site, so call (713) 931-0006 for that one.
Fluid section differences
The 4900 fluid section is built differently from the 6900 Plus, and that matters when you order wear parts. The 4900 fluid section lists a displacement rod (107-029), a repacking set (106-002A), a sleeve spring (106-116) and a major service kit (107-501). The Plus 6900 fluid section lists a piston rod (143-127), a repacking kit (138-153A), upper and lower packing springs 142-004 and 142-003, a minor kit 144-050 and a major kit (143-500).
Fluid section parts that differ
| Part | 4900 | 6900 Plus |
|---|---|---|
| Rod | Displacement rod 107-029 | Piston rod 143-127 |
| Packing | Repacking set 106-002A | Repacking kit 138-153A |
| Major kit | 107-501 | 143-500 |
| Outlet valve ball | 569-021 | 0509710 |
These are what the diagrams show. We do not claim any part fits both models.
What to confirm before you decide
Count the guns you run today
Three or fewer: either model fits the gun count. Four: the 6900 Plus.
Check the tips you spray
Compare your tip size with the maximum for the number of guns. Never exceed the maximum tip for your gun count.
Decide on gas or electric
Electric flow is listed lower than gas on the models that have both, so check it against your work.
Confirm model and serial
Open the 4900 main assembly or Plus 6900 main assembly. Call (713) 931-0006 if you are unsure which one you own.
Units and fluid section parts for the two models:
The Short Version
The larger pump is worth it if you run four guns, because the 4900 Plus stops at three. Below that the two are close on tip limits. The fluid sections use different parts, so order from the diagram for your own model.
