• 2150S-E, A14CS5-1SSPTPTPT
• Stainless steel fluid section, aluminum center section (specific to some models; for 2150S-E, construction may vary—check exact configuration for 657177)
• Compatible with a wide range of fluids, including water, chemicals, and lubricants
• Stall-free, low-pulsation air valve for smooth operation
• Up to 40% more efficient than previous models
• Up to 5 times longer diaphragm life
• Fewer parts for easier maintenance
• Externally accessible air valve for fast servicing
• Lube-free operation
• Epoxy-coated air section for tough environments

Applications:
Ideal for industrial fluid transfer, lubrication systems, chemical processing, and other applications requiring reliable, efficient, and low-maintenance pumping solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment of flanges and gaskets during installation
• Use recommended torque settings for bolts (e.g., 20–30 ft-lb for flange bolts)
• Lubricate bolt threads before installation
• Follow tightening sequence as specified in the manual
• Check for leaks and proper operation after installation
• Regularly inspect diaphragms and valves for wear
• Service air valve externally without removing the pump
• Use only recommended replacement parts
• Keep air supply clean and dry
