The GRACO 26D885 is a pulsation dampener designed to absorb pressure fluctuations and reduce vibration in fluid transfer systems. It is constructed from polypropylene with polypropylene seats and a PTFE/Santoprene 2-piece diaphragm, making it suitable for use with a wide range of compatible fluids in industrial applications.

Key Features:

• Pulsation Dampener
• i-Series, 1 in. (25.4 mm)
• Polypropylene (fluid section and seats), PTFE/Santoprene 2-piece diaphragm
• Maximum flow rate: 50 GPM (189 L/min)
• Maximum fluid pressure: 100 psi (0.69 MPa, 6.9 bar, 689 kPa)
• Compatible with fluids that are chemically compatible with polypropylene and PTFE/Santoprene
• Reduces pulsation and vibration in pipelines
• Protects downstream equipment and extends system life
• Minimizes noise, plumbing damage, and product degradation
• Ensures smooth, steady flow with reduced cavitation and foaming
• Made in the USA

Applications:
Industrial fluid transfer systems requiring pulsation and vibration reduction, suitable for use in various industries including mining, agriculture, and manufacturing.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems.
• Check all connections to ensure they are tight and use a compatible liquid thread sealant on all male threads (do not overtighten)
• Ensure the air breather or air exhaust line is securely connected to the air exhaust port on the top of the dampener
• Set the air supply pressure to at least 10 psig (0.07 MPa, 0.7 bar) above the mean liquid discharge pressure for best performance
• Always verify fluid compatibility with wetted and non-wetted parts before installation
• Regularly inspect connections and diaphragms for wear or damage
• Relieve all fluid pressure before performing maintenance by opening the fluid drain valve
• Follow manufacturer guidelines for fluid and solvent compatibility
