PowrCoat 960 Severe Service Fluid Section · Pump Assembly 155-559
Restore Consistent Priming, Pressure and Material Delivery
Shop verified PowrCoat 960 fluid pump components for the 155-559 assembly used on PowrCoat 745 and 960 systems. Titan documents the pump block, packing sets, displacement rod, piston valve, cylinder and foot-valve components required for professional fluid-section service.
PowrCoat 960 Fluid Pump Assembly Parts (155-559)
Titan’s official 155-559 exploded diagram identifies the fluid pump used on PowrCoat 745 and PowrCoat 960. The pump converts air-motor movement into coating intake and discharge through the displacement rod, upper and lower packings, piston valve and foot valve. Titan recommends routine service after approximately 1,000 operating hours or sooner when upper-packing leakage or uneven stroke speed appears.
Functions Supported by the Assembly
- Draws coating through the foot valve during the intake stroke.
- Pressurizes material through the piston valve and pump cylinder.
- Maintains sealing through upper and lower packing assemblies.
- Transfers air-motor movement through displacement rod 155-982.
- Supports controlled priming and steady high-pressure delivery.
When Repair Professionals Use This Page
- Correcting upper-packing leakage or pressure loss.
- Diagnosing faster movement on one pump stroke.
- Restoring weak priming or material pickup.
- Replacing scored rods, cylinders or valve components.
- Planning minor or major 155-559 pump service.
Operating Symptoms and Diagnostic Priorities
Relieve all stored air and fluid pressure before service. Inspect the connected components and confirm the actual failure before replacement.

Maintenance Priorities
- Use Titan 314-480 piston lubricant on the upper packing area.
- Inspect the displacement rod for scoring before installing packings.
- Keep suction connections sealed against air entry.
- Clean coating residue from valve seats and balls.
- Relieve pressure before opening the pump.
- Record hours and service near the 1,000-hour interval.
Plan a Complete Repair
Record the PowrCoat 960 model, diagram position, symptom and exact leak, restriction or wear location before disassembly. Photograph hose routing and component orientation where useful.
Inspect each mating pair during teardown and replace only after confirming the true failure point. This approach reduces unnecessary parts cost, repeat downtime and installation errors.
