The GRACO D5C331 is an air-operated double diaphragm (AODD) metal pump designed for reliable fluid transfer in industrial applications. It features an aluminum housing, stainless steel (SS) seat and ball, and a PTFE diaphragm, making it suitable for handling a wide range of fluids, including those requiring chemical resistance and durability. This pump is intended for use within GRACO equipment for safe, leak-free fluid transfer.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 716 AL, 3/4" NPT (Note: D5C331 is specified with BSP, but most Husky 716 AL models are 3/4" NPT; confirm BSP for exact model)
• Aluminum housing, stainless steel seat and ball, PTFE diaphragm
• 16 gpm (61 lpm) maximum free flow delivery
• Maximum fluid pressure: 100 psi (7 bar, 0.7 MPa); Air pressure operating range: 30–100 psi (2.1–7 bar, 0.21–0.7 MPa)
• Designed for integration with GRACO fluid handling systems and compatible with a wide range of industrial fluids
• No mechanical seals, reducing risk of fluid leaks or failures
• Runs quietly at less than 85 dBa with optional remote muffler
• Center- and end-porting options
• Easy-to-maintain design
• Reliable, robust construction for heavy-duty use
• Maximum suction lift: 15 ft (4.5 m) dry
• Maximum pumpable solids: 0.09 in (2.5 mm)
• Maximum ambient operating temperature: 180°F (82°C)

Applications:
Ideal for transferring a variety of fluids in industrial, mining, agricultural, and manufacturing environments. Suitable for applications requiring chemical resistance, leak-free operation, and reliable performance under demanding conditions.

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 proper alignment and secure mounting of the pump
• Use appropriate fittings for BSP or NPT connections as specified by the model
• Check air supply for correct pressure (30–100 psi)
• Inspect diaphragms and seals before installation
• Follow all safety guidelines and local regulations
• Regularly inspect and maintain diaphragms, balls, and seats for wear
• Perform routine maintenance as recommended by GRACO
• Monitor for leaks and unusual noise
• Replace worn parts promptly with genuine GRACO components
• Keep installation area clean and free of debris
