Internal drive rod for Graco pump assemblies, designed to transfer mechanical motion from the air motor to the fluid section for consistent pumping performance.
| Equipment Category | Graco Systems | Function of Component |
|---|---|---|
| Air-Operated Diaphragm Pumps | Select Graco AODD pump models | Transfers mechanical motion within the pump assembly |
| Fluid Handling Pump Systems | Graco industrial fluid transfer pumps | Connects moving components to drive fluid displacement |
| Air Motor Driven Pumps | Graco pneumatic pump systems | Converts air motor motion into pumping action |
The Graco 189055 Rod is an internal mechanical drive component used in Graco pump assemblies to transfer motion between the air motor and fluid section. It plays a key role in driving the pumping action during each cycle.
Built for industrial durability, it ensures consistent force transfer and reliable performance in high-pressure fluid handling systems.
