The GRACO 188605 is a PTFE (polytetrafluoroethylene) diaphragm designed for use in Husky™ 1040 air-operated double diaphragm pumps. This part is essential for the pump’s fluid handling section, providing chemical resistance and durability for demanding industrial applications.

Key Features:

• Diaphragm
• Husky™ 1040
• PTFE (polytetrafluoroethylene)
• GRACO Husky™ 1040, SaniForce 1040 air-operated double diaphragm pumps
• Chemical resistance due to PTFE material
• Designed for reliable, long service life in harsh environments
• Easy to replace as part of routine maintenance

Applications:
Used in industrial fluid transfer applications, especially where chemical resistance is required. Suitable for mining, agriculture, chemical processing, and other sectors requiring robust, maintenance-friendly pump components.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise chemical resistance and reliability.
• Follow the manufacturer’s instructions for diaphragm replacement to avoid leaks or damage.
• Ensure the pump is depressurized and isolated from fluid and air supplies before servicing.
• Inspect related components (O-rings, seals) for wear and replace if necessary during diaphragm installation.
• Refer to the equipment manual for torque specifications and proper assembly procedures.
