The PowrLiner 850 is Titan's entry-level, clutch-driven line striper: 3000 psi maximum pressure, 0.33 gpm maximum delivery, a 37.7 cc 4-stroke engine and one gun on a 1/4 in. x 50 ft hose. Titan positions it for smaller jobs on pavement, grass or turf, run by one operator. Larger jobs point to the hydraulic PowrLiner models.
Who the 850 is for
Titan describes the PowrLiner 850 as a striper for entry-level contractors, sports turf managers and maintenance personnel who need pavement, grass or turf lines on smaller jobs. It is built to be moved by one person, and Titan says it fits in most car trunks. Older manuals carry the SpeeFlo name ("SPEEFLO PowrLiner 550 / 850"), which is the same product line: Titan and SpeeFlo parts appear side by side on our diagrams.
The 850 sits at the bottom of the current PowrLiner range. Above it are the PermaStroke 3500 and the hydraulic 4955, 6955 and 8955, which Titan aims at heavier striping work. Parts and manuals remain available for the 850.
The spec sheet
PowrLiner 850 specifications
| Item | Spec | What it means in practice |
|---|---|---|
| Drive | Clutch-driven piston pump | A piston rod moves through packings, so the parts are the classic piston-pump set |
| Max pressure | 3000 psi | Lower ceiling than the 3500 and the hydraulic models, which are rated 3300 psi |
| Max delivery | 0.33 gpm | The lowest figure in the PowrLiner series, which Titan lists from 0.33 gpm to 2.50 gpm |
| Engine | 37.7 cc 4-stroke gas | A small engine; the fuel tank holds 0.17 US gallons |
| Line width | 2 in. to 12 in. | Per a dealer page built from the manual |
| Hose supplied | 1/4 in. x 50 ft | The hose connection is 1/4 in. NPS(M) |
| Gun | One, supplied | Dealer listings name it an LX-40; our gun diagram lists 759-369 Gun Assembly |
| Inlet filter | 10-mesh "rock catcher" | Keeps larger debris out of the pump |
| Pail | Carries a 5-gallon pail | Per a dealer listing |
Weight and maximum tip size are left out on purpose: Titan's page and manual-based dealer pages give different figures for both. Check your manual or call (713) 931-0006 if a job depends on them. Titan's item number on the site is 0290005A.
The 3000 psi rating is a ceiling, not a target. Pressure is set to suit the coating and the tip, and the manual is where that guidance lives. The pressure control on the 850 is called DirectLink, and Titan does not state a range that we can confirm, so we do not quote one.
Features Titan lists
- DirectLink pressure control to set spray pressure at the machine.
- AutoOiler: a button that delivers oil from the reservoir to the packings.
- Reversible gun mount that lets you stripe off the front tire or the rear tire.
- Removable gun for stenciling.
- Front wheel that can be locked straight or left free to caster.
- Folding handle for transport and storage.
Together these describe a machine meant to be taken to a lot and set up by one operator. The reversible gun mount and the lockable front wheel are the two that change how you work on the pavement: you choose which tire the gun stripes off, and you choose whether the front wheel tracks straight or casters.
A clutch-driven pump in plain words
Titan and dealer listings both call the 850 clutch-driven. The diagram shows what that means in parts: a clutch assembly and a recoil start on the main assembly page, and on the drive assembly page a 2nd stage gear assembly, a piston rod, a lower seal, an inlet valve assembly, a prime spray valve assembly and a fluid section repacking kit. The engine is listed there too, as 0293943, the PowrLiner 850 gasoline engine.
This is a different machine from the sealed hydraulic PermaStroke 3500, which Titan says has no piston, packings or clutch to wear or replace. If you are comparing the two, open the 3500/3500S pump assembly page next to the 850 drive page and the difference in parts is clear.
What 0.33 gpm limits
Delivery is the amount of material the pump can move, and the tip orifice decides how much of it leaves the gun. A larger orifice delivers more material and asks more of the pump, so a low-delivery machine works within a limited range of tip sizes. The manual gives tip guidance for the 850, but published maximum-tip figures differ between sources, so look it up in the manual for your unit.
The practical reading is the one Titan gives: the 850 is for smaller jobs. If your work moves a lot of paint per day or needs two guns at once, the hydraulic models, which Titan rates up to 2.50 gpm, are the machines built for it. Coating guidance, tip choice and spray pressure all belong to the manual, not to this page.
Parts and consumables to know
850 parts worth knowing by number
The 850 spray gun page has the tip seals and the filter, and the accessories page lists the wider range of TR1 tips and the other consumables. Use these pages in place of guessing: open the page, find the numbered callout and add the part.

The Short Version
The PowrLiner 850 is a clutch-driven entry machine at 3000 psi and 0.33 gpm, with a 37.7 cc engine and one gun. It is built for smaller jobs and one operator. The parts you will meet first are on the drive assembly, main assembly and spray gun pages. If a job needs more delivery or two guns, look to the 3500 or the hydraulic models.
