The GRACO Husky 515 is a compact, air-operated double diaphragm pump constructed primarily from polypropylene, with Santoprene balls and PTFE diaphragm (note: most sources specify Santoprene diaphragm, but PTFE is referenced in your product name; see note below). It is designed for reliable, leak-resistant transfer of a wide range of industrial fluids, including antifreeze, detergents, oils, and wastewater, in demanding environments.

Key Features:

• Air-operated double diaphragm pump
• Husky 515, 1/2" NPT
• Polypropylene fluid section and center, Santoprene balls, PTFE diaphragm (note: most sources list Santoprene diaphragm; confirm with supplier for PTFE)
• Up to 15 gallons per minute (GPM)
• Maximum fluid pressure: 100 psi (7 bar, 0.7 MPa)
• Antifreeze, detergents, resins, polymers, motor oil, grease & oil, hydraulic fluid, transmission fluid, cutting oil, water, wastewater, ink
• Stall-free, low-pulsation air valve for smooth operation and rapid changeover
• Bolt-through fluid cover design for enhanced safety and leak minimization
• No mechanical seals, reducing maintenance and contamination risk
• Lightweight (6.5–7.8 lbs), easy to install and service
• Reliable performance in demanding industrial environments

Applications:
Industrial fluid transfer, including antifreeze, detergents, oils, wastewater, and other compatible fluids. Suitable for mining, agriculture, manufacturing, and maintenance operations.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance, reducing downtime and maintenance costs.
• Ensure proper alignment of inlet and outlet ports
• Use appropriate thread sealant for NPT connections
• Verify air supply pressure does not exceed 100 psi
• Inspect diaphragms and balls for wear during installation and maintenance
• Follow all safety guidelines for handling industrial fluids
• Regularly inspect diaphragms, balls, and seals for wear or damage
• Replace worn components with genuine GRACO parts
• Keep pump and surrounding area clean to prevent contamination
• Monitor for leaks and unusual noises during operation
