Titan 185-551A Pump Assembly for PowrCoat and Admiral Sprayers
Titan 185-551A is the complete OEM fluid pump assembly for compatible Titan air-powered airless sprayers, including the PowrCoat 730 (30:1) and PowrCoat 940 (40:1), as well as Admiral wall mount and drum mount configurations that use the 185-551 pump. This assembly is the primary component responsible for drawing, pressurizing, and delivering coating materials within the spray system. It is supplied with leather/UHMWPE packings and is manufactured to OEM specifications for dependable fit and long service life. 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 uneven. Titan Piston Lube (Part #314-480) is the recommended upper packing lubricant; do not substitute oil, water, or solvent. During service, inspect the displacement rod and cylinder chrome for grooves, dents, or worn areas, and replace if the hard chrome is damaged. Inspect valve seats and replace if cracked or worn. Always verify fitment against your specific model and serial number before ordering.

The 185-551A Pump Assembly is the complete OEM replacement fluid pump for compatible Titan air-powered sprayers. During service, follow the pressure relief procedure first. Disassembly involves separating the pump from the motor, removing the siphon hose, stanchion nuts, coupling nut, and connecting rod, then unthreading the foot valve and removing the cylinder and displacement rod. Clean and inspect all parts, paying particular attention to the displacement rod and cylinder chrome for grooves, dents, or worn areas. Replace if hard chrome is damaged. Inspect valve seats and replace if cracked or worn. Reassemble using new packings and O-rings, lubricating with Titan Piston Lube (314-480) as specified. Verify compatibility against your specific model and serial number before ordering.
