Fluid section repair kit designed to restore sealing efficiency and chemical resistance in Graco 1590M diaphragm pumps using PTFE and acetal wear components.
| Pump Model | Fluid Section Configuration | Application |
|---|---|---|
| Graco 1590M Series | TP / AC / -- / -- | High-volume industrial fluid transfer and chemical pumping |
The Graco D0B520 Kit is an OEM fluid section repair kit designed for Graco 1590M diaphragm pumps. It restores sealing performance and fluid efficiency by replacing worn internal components in the pump’s fluid section assembly.
This kit combines PTFE (TP) sealing components with acetal (AC) wear parts to deliver strong chemical resistance, low friction operation, and long-lasting durability. The PTFE elements enhance sealing integrity under continuous high-pressure cycling, while acetal components provide stability and wear resistance in dynamic flow conditions.
It is intended for pump maintenance and rebuilds to restore performance, prevent leakage, and ensure consistent operation in demanding industrial environments.
