The GRACO 24T836 ToughTek M680a is a bare piston pump system with a stainless steel hopper, designed for industrial applications. It is intended for pumping and spraying abrasive, cementitious, and heavily filled materials such as epoxy mortars, non-skid coatings, and fireproofing compounds. The all-stainless design ensures easy cleanup and durability.

Key Features:

• Pneumatic Piston Pump Package
• M680a, 25 gal (95 L) hopper
• Stainless steel
• Maximum flow rate: 10.88 GPM (not always specified for this configuration, but consistent with M680a series)
• Maximum working pressure: 1000 psi (7 MPa, 70 bar)
• Cementitious materials, epoxy mortars, non-skid coatings, heavily filled polymers
• Explosion-proof for hazardous spray areas
• Low pressure pumping (200–500 psi/13.7–34.5 bar) reduces wear on pump lower
• Minimizes material waste and provides a consistent finish compared to hand-troweling
• Fast, easy cleaning with high velocity flush
• Quick disassembly for hand cleaning
• One convenient air source to run pump and atomize air
• Portable sprayer for mortar, cementitious, and heavily filled materials

Applications:
Industrial spraying of abrasive, cementitious, and heavily filled materials such as epoxy mortars, non-skid coatings (bridges, marine industry), fireproofing, and other solvent-based coatings.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Ensure all connections are secure and compatible with the material being pumped
• Follow manufacturer guidelines for setup and operation
• Regularly inspect and clean the hopper and pump components to prevent clogging and wear
• Use appropriate personal protective equipment (PPE) when handling hazardous materials
