Key Features:

• Diaphragm kit
• For 1-inch pump (1040 series)
• PTFE/EPDM overmold
• Compatible with GRACO 1040 series air-operated double diaphragm pumps
• Chemical resistance due to PTFE/EPDM overmold
• Designed for reliability and long service life
• Ease of maintenance as a replacement kit

Applications:
Suitable for use in industrial environments requiring chemical resistance, such as chemical transfer, paint, coatings, and other aggressive fluid handling applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of your pump system.
• Always follow the manufacturer’s instructions for diaphragm replacement.
• Ensure the pump is depressurized and isolated from fluid and air sources before maintenance.
• Inspect all related components (seals, gaskets, valves) for wear or damage during replacement.
• Regularly inspect diaphragms for signs of wear or chemical degradation.
• Replace diaphragms as part of a scheduled maintenance program to prevent unplanned downtime.
