The GRACO 655011 HUSKY PUMP,2150A-E,A04AA2SPSPSPPT is an air-operated double diaphragm pump designed for heavy-duty fluid transfer applications. It is available in polypropylene or PVDF construction for chemical compatibility and is engineered for lasting performance in demanding industrial environments.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 2150A-E, 2 in (51 mm) ANSI end-porting
• Polypropylene or PVDF (depending on variant), with options for aluminum or ductile iron center sections
• Up to 150 gpm (568 lpm) (varies by configuration and fluid)
• Maximum fluid working pressure: 120 psi (8.4 bar, 0.84 MPa)
• Designed for use with a wide range of fluids, including chemicals, water, and slurries; compatible with various GRACO systems and accessories
• Stall-free low pulsation air valve for smooth and rapid changeover
• Up to 40% more efficient than previous models
• Up to 5 times longer diaphragm life compared to industry peers
• Fewer parts for easier maintenance; externally accessible air valve
• Lube-free operation
• Epoxy-coated air section for tough environmental conditions

Applications:
Ideal for transferring chemicals, water, slurries, and other fluids in industrial, mining, agricultural, and manufacturing settings. Suitable for applications requiring high flow rates, chemical resistance, and reliable performance.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Ensure correct alignment of inlet and outlet ports
• Use appropriate gaskets and seals for the fluid being pumped
• Follow torque specifications for fasteners (e.g., 50–60 in-lb for valve cover screws)
• Lubricate actuator pistons and packings during assembly
• Regularly inspect and maintain the air valve and diaphragm for wear
• Consult the manual for specific installation and maintenance procedures
