SprayTech airless sprayers and the ED655 series share design heritage with the broader Titan product family, which means the maintenance principles are consistent — but the part numbers are model-specific and should always be confirmed before ordering.
SprayTech Model Overview
ED655 — The Most Common SprayTech Model
The SprayTech ED655 is a compact electric airless sprayer built for residential and light commercial applications. Its 5/8 HP DC motor drives a fluid section that accepts tip sizes up to 0.021 inch — the same output class as the Titan Impact 440, which makes it a familiar machine for contractors already comfortable with that size category.
The ED655 uses SmartControl technology that adjusts motor speed to maintain consistent pressure as the tip wears, which is a genuine operational advantage over fixed-speed electric machines. This also means the pressure control components are more complex than on a basic fixed-speed unit — pressure transducers and control boards are additional service items beyond the fluid section consumables.
Standard fluid section maintenance for the ED655 is identical in principle to any airless piston pump: packing wears first, valves second, piston rod inspection at every service. The part numbers are ED655-specific and should be confirmed against the diagram for that model at AllTitanParts.com rather than assumed to match Titan Impact components. Our SprayTech paint sprayer parts catalog covers the full ED655 and EP series parts inventory.
EP and EPX Series — Industrial Piston Pumps
The SprayTech EP2105 through EP2555 and EPX series are industrial-grade piston pumps designed for OEM integration and high-volume industrial coating applications — a different category from residential or commercial painting equipment. These units are serviced similarly to other piston pumps but with different component specifications and service intervals appropriate to their higher-duty applications.
Parts sourcing for the EP/EPX series requires matching against the specific model designation — the EP2105, EP2300, EP2555, and their EPX counterparts each have distinct fluid section configurations. For any EP or EPX model, always verify the exact part number against the OEM diagram for that specific unit before ordering. Repacking kits for EPX models are available and should be matched to the exact EPX variant, not assumed to be universal across the series.
Maintenance That Applies Across All SprayTech Models
Regardless of SprayTech model, the maintenance habits that extend fluid section life are consistent: keep the wet cup filled during operation, flush thoroughly after every job with the appropriate solvent, clean the suction filter weekly during active use, and never store the machine with water sitting in the fluid section.
The diagnostic approach is also consistent across models: pressure pulsing points to valve wear, material in the wet cup points to packing wear, slow priming points to either suction system issues or early-stage valve and packing decline. The same symptom-to-component logic that applies to Titan electric airless sprayer parts applies across SprayTech equipment.
