OEM fluid section repair kit designed to restore sealing performance and efficiency in Graco Husky 515 and 716 diaphragm pumps using stainless steel and PTFE components.
| Supported Equipment | Series / Model Details | Application Type |
|---|---|---|
| Graco Husky 515 | Air-operated double diaphragm pump (1/2 in.) | Fluid transfer, industrial pumping systems |
| Graco Husky 716 | Air-operated double diaphragm pump (3/4 in.) | Chemical transfer, coatings, industrial fluids |
| 515/715 IN SS Series | Stainless steel fluid section configuration | High-performance industrial fluid handling |
The Graco D05311 Kit is a genuine OEM fluid section repair kit designed specifically for Graco Husky 515 and 716 (515/715 IN SS series) air-operated double diaphragm pumps. It is engineered to restore the pump’s internal sealing and fluid-handling performance by replacing all critical wear components inside the fluid section.
This kit typically includes precision-engineered parts such as PTFE diaphragms, PTFE balls, stainless steel-compatible seats, and sealing components (O-rings and guides). These materials are selected to ensure chemical resistance, long service life, and reliable operation in demanding industrial environments.
The configuration SS, PT, PT, FKPT refers to the material composition of key internal components—stainless steel and PTFE-based sealing elements—optimized for aggressive fluids and high-performance pumping applications.
