The GRACO 24Y557 is an electric-operated double diaphragm pump system designed for industrial fluid transfer. It features an aluminum construction and is intended for applications requiring low pulsation, smooth flow, and efficient operation within GRACO equipment.

Key Features:

• Electric-operated double diaphragm pump
• Husky 1050e AL, 1 inch (25.4 mm) connection
• Aluminum center and fluid section
• Maximum free-flow delivery: 158 lpm (42 gpm)
• Maximum fluid pressure: 0.48 MPa (70 psi)
• Compatible with a wide range of fluids and industrial applications; multiple porting options available
• Low pulsation and smooth flow
• Self-priming and can run dry
• Up to 5x more efficient than air-operated diaphragm pumps
• Patented air-charged drive for reduced pulsation
• Stalls under pressure for safety
• Easy maintenance and reliable operation
• Cart-mounted for portability

Applications:
Ideal for industrial fluid transfer, including chemical processing, mining, agriculture, and other sectors requiring efficient, reliable, and low-pulsation pumping solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure all electrical installations comply with NEC and local codes
• Use appropriate mounting hardware for cart installation
• Check fluid compatibility before operation
• Regularly inspect diaphragms, balls, and seats for wear
• Refer to the manual for specific wiring and setup instructions
