The digital display provides real-time information including:

• Pressure

This makes it easier to monitor sprayer performance and track maintenance requirements.

WatchDog Pump Protection

Running an airless pump dry can cause unnecessary wear.

WatchDog Pump Protection monitors the sprayer and automatically shuts the pump down when the paint supply runs out.

This helps protect the pump while reducing unnecessary downtime and wear.

Endurance Vortex Piston Pump

The Ultra 450 uses Graco's Endurance Vortex Piston Pump.

The Vortex design automatically rotates the piston rod during operation to distribute wear and extend pump life.

Graco states that its Endurance Vortex pump is designed to spray 3X more gallons than the nearest competitor before requiring service.

ProConnect Pump Replacement

If pump service is eventually required, the ProConnect Pump Replacement System allows the pump to be replaced directly on the jobsite.

Pump swaps can be completed in minutes without loose pins or small parts, helping professional contractors minimize downtime.

The replacement pump for the Ultra 450 is:
