| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan replacement pump assembly designed to restore the performance, pressure output, and reliability of compatible Titan airless paint sprayers. This complete pump assembly is manufactured to OEM specifications for dependable fit and long service life. |
| Function | Pressurizes coating material and delivers consistent fluid flow from the container to the spray gun. The pump assembly draws material through the siphon hose, pressurizes it, and maintains controlled delivery for uniform spray patterns and high-quality finishes. |
| Industrial Applications | Commercial painting, industrial coatings, manufacturing facilities, infrastructure maintenance, construction projects, wood finishing, and metal finishing operations. |
| Compatible Titan Systems | Advantage Series; PowrCoat 730 (30:1); PowrCoat 940 (40:1); and other compatible Titan airless sprayers utilizing the 185-551A pump configuration. |
| Accurate Part Number | 185-551A Pump Assembly (Leather/UHMWPE packed). |
| Compatible Parts & Assemblies | Fluid sections, suction assemblies, pressure controls, filters, spray guns, manifolds, and prime valves. |
| Related Parts Commonly Serviced Together | Packing kits, piston rods, inlet valves, outlet valves, manifold filters, pressure sensors, and fluid hoses. |
| Common Problems Solved | Pressure loss, fluid leakage, poor atomization, difficult priming, excessive cycling, reduced productivity, uneven spray patterns, and reduced pumping efficiency. |
| Use with Coating Systems | Latex paints, primers, stains, acrylics, elastomerics, sealers, varnishes, polyurethanes, lacquers, and industrial protective coatings. |
| Service & Maintenance | The 185 Series Pump should receive a routine servicing after approximately 1000 hours of use or earlier if there is excessive leakage from the top packing, or if pump strokes become faster on one stroke or another. The use of Titan Piston Lube Part # 314-480 is recommended as an upper packing lubricant. Do not substitute oil, water, or solvent. |
| OEM & Brand Information | Genuine Titan OEM component manufactured to Titan specifications for dependable fit and long service life. Use of non-Titan manufactured service parts may void warranty. When servicing the pump, inspect the displacement rod's and cylinder's chrome for grooves, dents, or worn areas. Replace if hard chrome is damaged. Inspect valve seats and replace if cracked or worn. |
| Commercial Benefits | Reduces downtime, improves productivity, lowers maintenance costs, improves coating quality, restores factory-level pumping efficiency, and supports higher jobsite productivity. |
The 185-551A Pump Assembly is a complete OEM replacement fluid pump designed to restore the performance, pressure output, and reliability of compatible Titan airless paint sprayers. This pump assembly is the primary component responsible for drawing, pressurizing, and delivering coating materials within the spray system. The 185 Series Pump should receive routine servicing after approximately 1000 hours of use or earlier if there is excessive leakage from the top packing, or if pump strokes become faster on one stroke or another. The use of Titan Piston Lube Part # 314-480 is recommended as an upper packing lubricant. Do not substitute oil, water, or solvent. When replacing the pump assembly, inspect the displacement rod's and cylinder's chrome for grooves, dents, or worn areas, and replace if hard chrome is damaged. Use of non-Titan manufactured service parts may void warranty. Use genuine Titan components to ensure proper fit and reliable system operation.
