The GRACO 650528 is a robust air-operated double diaphragm pump designed for handling slurries and abrasives without damage. It is constructed with FK (fluoroelastomer) diaphragms and is intended for use in demanding industrial applications where gentle handling of shear-sensitive materials and dry-running capability are required.

Key Features:

• Air-Operated Double Diaphragm Pump
• 1050F-E
• FK (fluoroelastomer) diaphragms, S4A (specific material not detailed, but likely refers to a variant or additional feature; consult GRACO for specifics)
• Compatible with a wide range of industrial fluids, including slurries and abrasives
• Handles slurries and abrasives without damage
• Gentle on shear-sensitive materials
• Can run dry without damage
• No rotating or sliding parts in contact with fluid
• Durable pump technology

Applications:
Ideal for transferring slurries, abrasives, and shear-sensitive materials in industrial, mining, and agricultural settings. Suitable for applications requiring reliable, low-maintenance pumping solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and longevity of the pump. Non-genuine parts may compromise safety and efficiency.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses for the intended fluid
• Check air supply and pressure before operation
