The GRACO 25B451 PTFE Diaphragm Kit is a replacement diaphragm kit made from PTFE (polytetrafluoroethylene), designed for use in 2-inch air-operated double diaphragm (AODD) pumps. This kit is intended to restore or maintain the performance and reliability of GRACO pumps by providing a durable, chemical-resistant diaphragm suitable for demanding industrial applications.

Key Features:

• Diaphragm Kit
• For 2-inch Pump
• PTFE (polytetrafluoroethylene)
• Designed for use with GRACO 2-inch AODD pumps (e.g., SaniForce 2150, Husky 2150 series)
• PTFE material offers excellent chemical resistance and durability
• Designed for easy replacement and maintenance
• Supports reliable pump operation in harsh environments

Applications:
Ideal for use in industrial, sanitary, and chemical transfer applications where resistance to aggressive fluids and frequent maintenance are required. Commonly used in food processing, chemical manufacturing, and other industries requiring hygienic or robust pump solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise pump reliability and void warranties.
• Follow the pump manufacturer’s instructions for diaphragm replacement
• Ensure the pump is depressurized and isolated from the system before starting work
• Inspect all components for wear or damage during replacement
• Use appropriate tools and safety equipment
• Regularly inspect diaphragms for signs of wear or chemical degradation
• Replace diaphragms at recommended intervals or when performance issues are detected
• Keep spare kits on hand to minimize downtime
