The GRACO 515 Polypropylene Split Inlet Manifold is a component designed for use with GRACO Husky™ 515 air-operated double diaphragm pumps. It is constructed from polypropylene, a durable and chemically resistant plastic, and is intended to facilitate the simultaneous pumping or mixing of two fluids within the pump system.

Key Features:

• Split Inlet Manifold
• Husky™ 515
• Polypropylene
• Up to 15 GPM (when used with Husky 515 pump)
• Compatible with GRACO Husky™ 515 pumps; suitable for use with various fluids including antifreeze, detergent, resin, polymer, motor oil, gear oil, hydraulic fluid, automatic transmission fluid, cutting oil, and water
• Split manifold design allows for simultaneous pumping or mixing of two fluids
• No mechanical seals to cause fluid leakage
• Easy-to-service design
• Reliable performance in demanding environments
• Available in multiple materials for different chemical compatibility needs

Applications:
Used in industrial and maintenance applications requiring the transfer or mixing of two fluids, such as lubrication systems, chemical transfer, and maintenance operations in mining, agriculture, and manufacturing.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety of the pump system.
• Install new o-rings and the new split inlet manifold as per instructions
• Torque manifold nuts to 80–90 in-lb (9–10 N-m)
• Ensure all manifold connections are secure and properly sealed
• Follow all safety warnings and instructions provided in the manual
• Regularly inspect o-rings and manifold for wear or damage
• Replace o-rings and manifold as needed to prevent leaks
• Use only compatible fluids as specified by GRACO
