The gas PowrTwin 4900 Plus delivers up to 1.50 gpm (5.7 L/min) at up to 3300 psi (22.8 MPa) and runs up to three guns, with a 0.022 in. maximum tip on three guns. The electric 4900 Plus is rated at 1.10 gpm (4.2 L/min). Titan's page and the Plus manual agree on these figures.
Spec snapshot
The 4900 Plus is the smallest pump in the Plus line. Like every PowrTwin it is hydraulic-drive: the engine or motor turns a hydraulic motor, and that motor strokes a piston fluid section. Titan describes the pump as slow-stroking. These are the gas figures that Titan's product page and the Plus operating manual both give.

| Maximum delivery | 1.50 gpm (5.7 L/min) |
| Maximum pressure | 3300 psi (22.8 MPa) |
| Pressure control range | 400 to 3300 psi, per Titan's page |
| Number of guns | Up to 3 |
| Maximum tip, 3 guns | 0.022 in. |
| Complete unit on the site | 0290012 |
Titan's page and its manual disagree on the engine make and on the 1-gun and 2-gun tip sizes, so we do not print them. Check the plate on your own sprayer and the manual that came with it.
Two things follow from the gun count. The tip limit applies to the whole system, so a 0.022 in. tip on each of three guns is the ceiling, not a target. And pressure only needs to be high enough to atomise the coating: Titan's manual says extra pressure wears tips and adds overspray, and that running the engine faster does not raise working pressure.
The electric 4900 Plus
Titan lists a 4900 Plus electric version with a 2 HP DC motor. Its flow is lower than the gas pump, and the tip limits are listed for one, two and three guns, as Titan's page and the Plus manual agree:
PowrTwin 4900 Plus, electric model
| Item | Figure |
|---|---|
| Maximum delivery | 1.10 gpm (4.2 L/min) |
| Maximum pressure | 3300 psi |
| Maximum tip, 1 gun | 0.031 in. |
| Maximum tip, 2 guns | 0.028 in. |
| Maximum tip, 3 guns | 0.022 in. |
The manuals ask for a 20 amp outlet. They advise keeping the sprayer within 10 to 15 feet of the outlet with a short cord and a long paint hose, and if you must use an extension cord, using only a grounded 3-wire #12 cord. After an overload, turn the sprayer off, relieve pressure, wait about 30 minutes and push in the manual reset button. The site lists a 978-040 circuit breaker reset and a 506-260 on/off switch on the 4900 Plus accessories page.
What comes with the gas unit
According to Titan's product page, the gas 4900 Plus ships with an RX-Pro gun, a 517 tip and a 1/4 in. x 50 ft airless hose. The manual asks for at least 50 ft of nylon airless hose in any case. If you plan to run more than one gun, you add a manifold on the single gun outlet and plug the unused outlets, and the tip must drop to the multi-gun limit above. The 4900 gun manifold page lists the manifold parts.
For coatings, the tip chart in the Plus manual gives starting orifices: 0.013 in. to 0.017 in. for solid stains and house paints, 0.017 in. to 0.019 in. for primers, and 0.019 in. to 0.023 in. for dry fall and one-coat paints. On three guns the 0.022 in. limit covers only part of that last range, so check the tip against the gun count before you size up a coating job.
What its fluid section uses
The 4900 fluid section is built differently from the 6900, 8900 and 12000 Plus pumps, so a part number from a larger model is a bad assumption. The PowrTwin 4900 Fluid Section Parts page lists these parts, among others:
4900 fluid section parts from the diagram
Titan's manual says routine fluid section service comes at about 1,000 hours of use, sooner if the top packing leaks or one stroke becomes faster than the other. It also says a foot valve seat or outlet valve seat worn on one side can be flipped to the unused side, and replaced only when both sides are worn. The complete 4900 fluid section is on the site as 107-005.
Finding 4900 parts
Confirm the model
Read the model and serial number from the sprayer. PowrTwin diagrams exist for several generations, so a 4900 Plus part is not necessarily the same as one for an older 4900 XLT or 4900GH.
Open the matching diagram
The sections titled PowrTwin 4900 and PowrTwin 4900 Plus Accessories carry the Plus layout. Start with the fluid section, hydraulic motor or main assembly page.
Match the callout
Find the numbered callout, add that part, and use the accessories page for Piston Lube, manifold filters and the electric parts.

The Short Version
The gas 4900 Plus is a 1.50 gpm, 3300 psi pump for up to three guns, and the electric version drops to 1.10 gpm. Keep the tip at or under 0.022 in. on three guns, order fluid section parts from the 4900 page and not from a larger model, and call us if the diagram leaves any doubt.
