The GRACO 248174 Husky 515 is an air-operated double diaphragm pump constructed primarily from polypropylene, with polypropylene center section and seats, and TPE (thermoplastic elastomer) balls and diaphragm. It is designed for reliable, leak-free transfer of a wide range of fluids in industrial and maintenance applications.

Key Features:

• Air-operated double diaphragm pump
• Husky 515, 1/2 inch (13 mm) NPT ports
• Polypropylene center section, polypropylene seats, TPE balls, TPE diaphragm
• 15 GPM (57 L/min)
• Maximum fluid working pressure: 100 psi (7 bar, 0.7 MPa)
• Compatible with a wide range of fluids, including corrosive and abrasive liquids
• ATEX, CE (for certain configurations)
• Stall-free, low pulsation air valve for smooth operation
• No mechanical seals to prevent leaks
• Easy-to-service air valve and ball checks
• Rugged polypropylene construction resists corrosion
• Runs quietly (<85 dBa), with remote muffler option
• Bolt-through fluid cover design for leak elimination and safety
• Split manifold option for pumping multiple fluids without mixing

Applications:
Ideal for transferring chemicals, solvents, paints, coatings, and other industrial fluids in environments requiring corrosion resistance and reliability. Suitable for use in mining, agriculture, manufacturing, and maintenance operations.

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 all connections are tight and leak-free before operation
• Use appropriate thread sealant for NPT connections
• Check air supply for correct pressure (operates on as little as 20 psi)
• Install remote muffler if noise reduction is required
• Regularly inspect and service air valve and ball checks for optimal performance
