The GRACO D03001 PTFE Diaphragm Kit is a replacement diaphragm kit made from PTFE (polytetrafluoroethylene), designed for use in 3/8-inch air-operated diaphragm pumps. It is intended to restore or maintain the sealing and pumping performance of compatible GRACO pumps, ensuring reliable fluid transfer in industrial applications.

Key Features:

• Diaphragm repair kit
• For 3/8-inch pump
• PTFE (polytetrafluoroethylene)
• Compatible with GRACO 3/8-inch air-operated diaphragm pumps (e.g., Husky 307 series)
• Designed for simplicity and reliability
• Features fewer components for easier maintenance
• PTFE material offers chemical resistance and durability

Applications:
Industrial fluid transfer, including handling antifreeze, detergents, motor oil, hydraulic fluid, cutting oil, water, wastewater, and ink in compatible GRACO pumps[3][5].

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and safety of the pump system.
• Follow the manufacturer’s instructions for diaphragm replacement
• Ensure the pump is depressurized and isolated from fluid and air sources before installation
• Inspect all related components for wear or damage during replacement
• Regularly inspect diaphragms for signs of wear or chemical degradation
• Replace diaphragms as part of routine maintenance to prevent pump failure
• Use only compatible replacement kits to maintain system integrity
