The GRACO A12300029 is a diaphragm made from ultra-high molecular weight polyethylene (UHMW), designed for use in GRACO diaphragm pumps and related equipment. Its primary function is to provide a flexible, durable barrier between air and fluid sections, ensuring reliable and leak-free operation in demanding industrial applications.

Key Features:

• Diaphragm
• Ultra-high molecular weight polyethylene (UHMW)
• Designed for use in GRACO diaphragm pumps and compatible equipment
• High chemical resistance and durability due to UHMW material
• Flexible and reliable for long service life
• Suitable for demanding industrial environments

Applications:
Used in GRACO air-operated diaphragm pumps for transferring a variety of fluids, including oils, water, and chemicals, in industrial, mining, and agricultural settings.

Installation Notes:

• Using genuine GRACO diaphragms ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Ensure the pump is depressurized and isolated from all fluid and air sources before installation.
• Inspect the diaphragm for any defects or damage prior to installation.
• Follow the manufacturer’s recommended torque and assembly procedures for diaphragm replacement.
• Apply appropriate lubricants as specified in the manual to ensure smooth operation and extend diaphragm life.
• After installation, test the pump for leaks and proper function before returning to service.
• Regularly inspect diaphragms for wear, cracks, or chemical degradation.
• Replace diaphragms at recommended intervals or at the first sign of failure.
• Keep spare diaphragms on hand for critical applications to minimize downtime.
