The GRACO 26D878 is a pulsation dampener designed to reduce pulsation and vibration in fluid transfer systems. It is constructed from aluminum with stainless steel (SS) seats and a PS diaphragm, intended to improve system efficiency and protect downstream equipment by minimizing stress and maintaining product quality.

Key Features:

• Pulsation Dampener
• i-Series, 2 in. (50.8 mm)
• Aluminum body, 316 Stainless Steel seats, PS diaphragm
• Maximum flow rate: 150 GPM (568 L/min)
• Maximum fluid pressure: 120 psi (0.83 MPa, 8.3 bar, 827 kPa)
• Designed for use with GRACO fluid transfer systems; compatible with NPT connections
• ATEX hazardous location approval
• Minimizes fluid shearing and improves product quality
• Reduces stress on downstream equipment, extending system life
• Absorbs surges and reduces pressure spikes
• Controlled pulsation for consistent flow and minimized vibration
• Creates a safer work environment by reducing noise and plumbing damage

Applications:
Used in industrial fluid transfer processes where reducing pulsation and vibration is critical to protect equipment and maintain product integrity. Suitable for applications in mining, agriculture, and other industries requiring reliable fluid handling.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with GRACO equipment.
• Ensure proper alignment and secure NPT connections
• Follow manufacturer guidelines for pressure and temperature limits
• Regularly inspect for wear and maintain as recommended
• Periodically check diaphragm and seat condition
• Monitor for leaks or abnormal noise
• Replace worn components with genuine GRACO parts
