The GRACO 24X485 ChemSafe™ 1590 is an air-operated double diaphragm pump designed for safe and reliable transfer of corrosive or hazardous fluids. It features a UHMWPE housing, PTFE balls and seat, and an overmolded PTFE diaphragm, making it highly resistant to chemical attack and suitable for demanding industrial environments.

Key Features:

• Air-Operated Double Diaphragm Pump
• ChemSafe™ 1590, 1-1/2" NPT Connection
• UHMWPE housing, PTFE balls and seat, overmolded PTFE diaphragm
• 85.2 GPM (as listed for 24X485); some sources list up to 100 GPM for similar models (e.g., 24X421)
• Maximum fluid pressure: 0.7 MPa (approx. 100 psi) for 24X421; 24X485 may be similar but not explicitly stated
• Compatible with a wide range of corrosive and hazardous fluids due to PTFE and UHMWPE construction
• CNC machined design for precision fit and superior chemical containment
• Corrosion-resistant exterior with no exposed metal
• Removable air motor for easy maintenance
• Overmolded PTFE diaphragm for enhanced chemical resistance and reliability
• Low maintenance and long service life

Applications:
Ideal for transferring corrosive, abrasive, or hazardous chemicals in industrial, chemical processing, mining, and agricultural applications. Suitable for environments requiring high chemical resistance and reliable fluid transfer.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise chemical resistance and reliability.
• Ensure all connections are tight and leak-free before operation
• Use compatible piping and fittings rated for the intended fluid and pressure
• Follow manufacturer guidelines for air supply and pressure settings
• Regularly inspect diaphragms and fluid path components for wear or damage
• Refer to the equipment manual for specific installation and maintenance procedures
