The GRACO P21DC1 is a positive displacement, 2-ball piston pump designed for uniform and easily controlled delivery of paints and coatings. It is constructed for durability and features an NXT motor, making it suitable for demanding supply applications. The pump is engineered to handle a broad range of materials and is ideal for use in industrial environments where reliable, high-pressure pumping is required.

Key Features:

• Pneumatic Piston Pump
• P21DC1, 21:1 ratio
• Durable, positive displacement, 2-ball piston design
• Maximum flow rate: 3.4 GPM (as per some sources; official GRACO documentation may specify different values for similar models, but this is the most specific available for P21DC1)
• Maximum air inlet pressure: 100 psi; maximum working pressure not explicitly specified for P21DC1, but similar models handle up to 1190 psi (82 bar)
• Designed for use with a broad range of paints and coatings; compatible with GRACO supply systems
• Uniform and easily controlled delivery
• High pump pressure and flow performance
• Improved serviceability with fewer parts and faster repairs
• Lower ownership cost
• Monitor and protect your pump with DataTrak (if equipped)

Applications:
Ideal for supply applications in industrial environments, including painting, coating, and material transfer operations where high pressure and reliable delivery are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Follow manufacturer guidelines for air inlet and outlet connections
• Ensure proper thread sealant is used for air connections (e.g., Loctite 567 Low Strength Thread Sealant referenced in product literature)
• Regularly inspect and maintain packing and seals for long service life
• Monitor system diagnostics and runaway control features if available
• Consult the equipment manual for detailed installation and maintenance procedures
• Use only recommended lubricants and sealants
• Schedule regular maintenance to prevent downtime and extend pump life
