The GRACO D42D05 Husky 515 Polypropylene Pump is an air-operated double diaphragm pump constructed primarily from polypropylene, with a remote polypropylene center section, urethane duckbill seats, and a TPE (thermoplastic elastomer) diaphragm. It is designed for reliable, leak-free transfer of a wide range of fluids, including those with small solids, in industrial and maintenance applications.

Key Features:

• Air-Operated Double Diaphragm (AODD) Pump
• Husky 515, 1/2 inch (13 mm) connections
• Polypropylene (main body), remote polypropylene center section, urethane duckbill seats, TPE diaphragm
• Up to 15 gpm (57 lpm)
• Maximum fluid working pressure: 100 psi (7 bar, 0.7 MPa)
• Compatible with a wide range of fluids, including those with solids up to 0.09 in (2.5 mm)
• Stall-free, low pulsation air valve for smooth operation
• Bolt-through fluid cover design eliminates leaks and enhances safety
• No mechanical seals to prevent fluid leaks or failures
• Runs quietly at less than 85 dBa with remote muffler capability
• Easy-to-service air valve and ball checks
• Operates on as little as 20 psi (1.4 bar, 0.14 MPa)
• Split manifold option available for pumping multiple fluids without mixing
• Reliable air valve for years of dependable performance

Applications:
Ideal for transferring fluids in industrial, maintenance, lubrication, and process applications. Suitable for use in mining, agriculture, and other sectors requiring robust, leak-free fluid handling.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose
• Ensure all connections are secure and compatible with the pump’s porting (NPT for polypropylene standard porting)
• Regularly inspect and maintain the air valve, ball checks, and diaphragms for optimal performance
• Follow GRACO’s recommended maintenance schedule and use only approved replacement parts
