Pump Head Assembly Overview

Buy Genuine Titan ED655 Plus Pump Head Replacement Parts

The Titan ED655 Plus Pump Head Assembly is the fluid-handling section of the ED655 Plus airless sprayer. Working with the hydraulically actuated diaphragm pump, the pump head helps control coating intake, priming, fluid direction and pressurized material delivery to the spray hose.

Its inlet and outlet check valves help regulate the direction of coating movement. The prime/spray valve provides the designated fluid routing required during priming and spraying, while seals, washers, valve seats and fittings help maintain properly assembled fluid connections.

AllTitanParts lists individual components for this assembly, including the 0278242 Inlet Valve Assembly, 0278334 Paint Pump Block, 0555850 Prime/Spray Valve Assembly, 0278241 Ball Cage Seat Assembly, 0093635 Outlet Ball and 0278335 Outlet Fitting.
