The GRACO Husky 1590 PVDF is an air-operated double diaphragm pump constructed from PVDF (polyvinylidene fluoride), designed for handling aggressive chemicals and corrosive fluids within GRACO fluid handling systems. It is intended for industrial applications requiring robust chemical resistance and reliable fluid transfer.

Key Features:

• Air-operated double diaphragm pump
• Husky 1590, 1-1/2" (38.1 mm) NPT
• PVDF (polyvinylidene fluoride) wetted parts, AL (aluminum) center section
• Up to 379 L/min (100 US gal/min) at maximum air pressure
• Maximum fluid working pressure: 120 psi (8.4 bar, 0.84 MPa)
• Designed for use with aggressive chemicals and corrosive fluids; compatible with GRACO fluid handling systems
• Patented, high-reliability closed center air valve
• Online serviceable air valve for easy maintenance
• Epoxy-coated air section for tough environmental conditions
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps in its class
• Fewer parts than industry peers, air valve externally accessible for quick servicing without uninstalling the pump

Applications:
Ideal for chemical processing, water treatment, mining, and industrial applications requiring transfer of corrosive or abrasive fluids.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety in demanding industrial environments.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses rated for the intended fluid and pressure
• Follow manufacturer guidelines for air supply and fluid connections
• Regularly inspect and maintain the pump, especially the diaphragm and air valve, for extended service life
