Titan's weekly volume for the Impact 840 is 200-300 gallons, aimed at medium to large residential, commercial and industrial work. It delivers up to 1.00 gpm and takes a tip up to 0.032 in. with one gun. That is a recommendation, not a limit. The Impact 740 sits below it and the Impact 1140 above it.
What Titan rates the 840 for
Titan's page for the Impact 840I gives a recommended weekly volume of 200-300 gallons and describes the sprayer for medium to large residential, commercial and industrial projects. That figure is a guide to what the sprayer is built to handle in a normal week. It is not a hard stop, and it does not account for how thick your coating is or how long your hose runs, so treat it as a place to start.
The same figures apply to the Impact 840 across its versions: 1.00 gpm maximum delivery, 3300 psi maximum pressure and a 2.3 hp brushless motor. The site's Impact 840 model page lists a maximum hose length of 300 feet.
What that means for the tip
The tip orifice controls how much material comes out of the gun, and a bigger orifice draws more of the pump's delivery. Titan lists the largest tip the 840 can run as 0.032 in. with one gun and 0.021 in. when two guns share the pump. If your usual work needs a larger orifice than that, the 840 is the wrong size for it.
Tips wear. A worn tip has a wider orifice, so pressure falls and the pattern gets coarse, and a tip that has worn past its limit is a poor guide to whether the pump is too small. Fit a new tip before you decide a sprayer is under-sized. The tip seat and seal kit 661-020 is listed on the 840 accessories page.
Coatings Titan lists
Titan lists stains, lacquers, enamels, latex and block fillers for the 840. That is a painting and finishing list for larger jobs. Smooth texture and abrasive coatings such as level 5 finishes, knockdown and high-build coatings are listed against Titan's Impact 1040T and 1640 by dealers quoting Titan, not against the 840. If heavy texture is your main work, read the 1040T and 1640 specs before buying an 840.
Where the neighbours sit
Impact models around the 840 (Titan figures)
| Model | Max delivery | Max tip, one gun | Titan weekly volume |
|---|---|---|---|
| Impact 640 | 0.70 gpm | 0.027 in. | 75-100 gallons |
| Impact 740 | 0.80 gpm | 0.029 in. | 150-200 gallons |
| Impact 840 | 1.00 gpm | 0.032 in. | 200-300 gallons |
| Impact 1140 | 1.20 gpm | 0.034 in. | 300-400 gallons |
Weekly volumes are Titan's recommendations. We leave the 1040 out because the published volume for it conflicts between sources.
The 840 sits between the 740 and the 1140. If you are not close to 150 gallons a week, the 740 is the nearer match on Titan's figures; if your weeks run toward 300 gallons or beyond, the 1140 is listed for more. We do not rank them, since the right choice depends on your work, and weekly volumes are no more than the manufacturer's guide.
Versions to choose from
There is the original Impact 840, the 840I and the 840IA. The 840I and 840IA are IntelliSync models with a Bluetooth link to the MyTitan app. Titan lists DigiTrac against the 840I and ActivGuard GPS tracking against the 840IA. Each IntelliSync version comes as a high rider or low rider: 840I high rider 2419303, low rider 2419300, 840IA high rider 2419222, low rider 2419297.
High rider and low rider differ in the cart, which matters for parts. If you own one already, the cart diagrams are the upright cart page for a high rider and the low rider cart page.
Check the parts before you buy
Before buying, or when deciding whether to keep an older 840, look at the parts diagrams. The fluid section and main assembly pages list every part by callout, and the accessories page lists the consumables. Seeing the parts you would need later is a fair part of deciding on a sprayer.
If you are weighing the 840 against another model, call (713) 931-0006 with the coatings you spray and your weekly volume, and our parts team can help with fitment and parts. Titan's owner's manuals are on our manuals page.
