The GRACO 657118 Husky 2150S-E is an air-operated double diaphragm (AODD) pump designed for robust fluid transfer applications. It is constructed with materials such as aluminum, ductile iron, or stainless steel (specific to model), and is intended for use in demanding industrial environments where reliable, efficient, and maintenance-friendly pumping is required.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 2150S-E
• Aluminum, ductile iron, or stainless steel (model dependent)
• Up to 150 gpm (568 lpm)
• 120 psi (8.4 bar, 0.84 MPa)
• Compatible with a wide range of fluids, depending on wetted materials; always check chemical compatibility with pump materials
• ATEX certified for hazardous environments (model dependent); see manual for specific ratings
• 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 environments
• 2-inch ANSI end-porting

Applications:
Ideal for transferring fluids in industrial, mining, agricultural, and manufacturing settings. Suitable for handling abrasive, viscous, or corrosive fluids, as well as slurries and solids up to 0.25 inches (6.3 mm) in size.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Always follow the manufacturer’s installation instructions and safety guidelines
• Ensure all fluids and solvents are chemically compatible with pump materials
• Never move or lift the pump under pressure; always relieve pressure before handling
• Have two people lift the pump if necessary due to its weight
• Regularly inspect and maintain the air valve and diaphragm for optimal performance
