PowrCoats do not share one fluid section. The 730 and 940 use pump 185-551, the 745 and 960 use pump 155-559, the 975 uses 0533908, the 630 has its own pump, and the 1045, 1064 and 1072 each have their own diagram. Open the fluid pump page for your model and order the rod, piston seat and foot valve from that page only.
Why the pump number matters
A PowrCoat is a family of sprayers rather than one machine, and the fluid pumps inside it are not interchangeable by default. The site's diagrams show it plainly: the titles of the fluid pump pages carry a pump number for some models (185-551, 155-559, 0533908) and nothing for others, and the part numbers on those pages are different. Order a displacement rod from the wrong page and you will have the right-looking part for the wrong sprayer.
Take care with the word shared. When two models point at the same pump number, it means their diagram pages are built around the same pump. It does not promise every part number on the two pages is the same, and the examples further down show where they differ.
Model to pump table
Which fluid pump page belongs to which PowrCoat
| Model | Pump as the diagram names it | Diagram page |
|---|---|---|
| 630 | Its own pump, no number in the title | 630 Fluid Pump Assembly |
| 730 | 185-551 | 730 Fluid Pump Assembly (185-551) |
| 940 | 185-551 | 940 Fluid Pump Assembly (185-551) |
| 745 | 155-559 | 745 Fluid Pump Assembly (155-559) |
| 960 | 155-559 | 960 Fluid Pump Assembly (155-559) |
| 975 | 0533908 | 975 Fluid Pump Assembly 0533908 |
| 1045 | Its own pump, part names tagged WL45 | 1045 Fluid Pump Assembly |
| 1064 | Its own pump, part names tagged WL64 | 1064 Fluid Pump Assembly |
| 1072 | Its own pump, part names tagged wl72 | 1072 Fluid Pump Assembly |
The AirCoat models are separate sprayers, so use the AirCoat 620 fluid pump page or the AirCoat 423 fluid pump page for those. The WL45, WL64 and wl72 tags appear in the names of the 1045, 1064 and 1072 parts. Titan does not explain what they stand for, so do not read anything into them beyond a way to spot which model a part is listed for.
Key parts on each pump
Three parts do most of the identifying: the rod that the air motor drives, the piston seat assembly, which holds the ball valve in the piston, and the foot valve assembly at the inlet end of the pump. These are the numbers as the site's diagrams list them.
Rod, piston seat and foot valve by model
| Model | Rod | Piston seat | Foot valve |
|---|---|---|---|
| 630 | 0533609 (called a piston rod) | 0533611 | 0533615 |
| 730 and 940 | 185-984A | 182-921A | 183-992 |
| 745 and 960 | 155-982 | 155-921 | 155-991 |
| 975 | 138-917 | 143-945A | 140-991 |
| 1045 | 0533677 | 0533679 | 0533684 |
| 1064 | 0533689 | 0533691 | 0533695 |
| 1072 | 0533939 | 0533942 (listed as a stud piston/seat assembly) | 0533695 |
These come from the site's diagram pages. Use them to check you are on the right page, then confirm fitment with the parts team if you are unsure.
Look at the pairs that share a pump. The 730 and 940 pages list the same rod, piston seat and foot valve, but the 730 lists a 155-906 upper packing spring where the 940 lists 182-906. The 745 and 960 pages match on rod, seat and foot valve, and the 960 page adds a 155-052A upper packing assembly that the 745 page does not show. The 1064 and 1072 pages list the same foot valve, 0533695, and the same ball seat, 0533694, but they have different rods, glands and packing kits. So the rule is simple: order from the page for your model, never from the page of the model that looks closest.
Which pieces wear and which rarely change
Inside any of these pumps the usual wear items are the packings, the O-rings, and the balls and seats of the two valves. A worn packing shows as leaking at the wet cup, paint in the wet cup, or pressure that will not hold. A worn ball or seat shows up as pulsing, lost pressure or a pump that will not prime. Those are the parts to stock first.
The rod and cylinder are the long-life parts. Titan says the piston rod and cylinder have an exclusive hard-chrome plating and lists tungsten carbide valve seats and self-adjusting packings, but it does not publish a service life for any of them. The rod still needs a look every time the packings come out, because a scored rod will ruin new packings. Replace on inspection, not on a calendar.
For the models that have a kit, one order covers the set. The 975 page lists the 138-153A repacking kit. The 1045 page lists the 0533936 fluid pump repair kit. The 1064 page has the 0533937 repair kit and the 0533894 PTFE packing kit. The 1072 page lists the 0533938 service kit and the 533895 packing kit. We do not list what each kit contains here, so confirm that with our parts team before you buy, and note that the 630, 730, 745, 940 and 960 pages list individual packing sets rather than a named kit.
Looking up your part from the diagram
Start from your model number
Read it off the sprayer's tag: 630, 730, 745, 940, 960, 975, 1045, 1064 or 1072.
Open that model's fluid pump page
Use the table above. Do not start from a different model's page because it looks similar.
Match the callout to the part name
Find the numbered callout, read the part name, and add that part. A displacement rod, a piston seat assembly and a foot valve assembly each have their own callout.
Watch the WL tags
On the 1045, 1064 and 1072, part names carry WL45, WL64 or wl72. A part tagged for another model is a warning, not a match.
Call if it is still unclear
Phone (713) 931-0006 with the model and serial number. Do not assume a part will interchange between pumps.
Where to go next
Once you know your pump, the packing routine and lubricant are in our PowrCoat packings and Piston Lube guide. The features Titan calls Severe Service, and which diagram parts they are, are in the Severe Service fluid section guide. For the 975 pump part by part, see the 975 fluid pump breakdown.
Rods and piston seat assemblies from the pump pages above:
The Short Version
Match your model to its pump in the table, open that model's fluid pump page, and order the rod, piston seat, foot valve and packings from it only. Even models that share a pump number can differ in small parts, so use the page for your own model.
