The GRACO 24T835 ToughTek M680a is a pneumatic piston pump system designed for industrial applications, constructed from stainless steel. It is intended for pumping heavily filled, abrasive materials such as cementitious mortars, epoxy mortars, and non-skid coatings, providing a robust alternative to hand troweling.

Key Features:

• Pneumatic Piston Pump Package
• ToughTek M680a
• Stainless Steel
• 10.88 GPM
• Maximum Working Pressure: 1000 psi (7 MPa, 70 bar, 7000 kPa)
• Cementitious materials, epoxy mortars, non-skid coatings, difficult polymers with fillers (e.g., glass flake, silica, sand)
• Explosion proof for hazardous spray areas (where specified in certain configurations)
• Low pressure pumping (200–500 psi/13.7–34.5 bar) reduces wear on pump lower
• Flex Hose Applicator for handling heavily filled materials
• Engineered for durability with heavy-duty materials
• Fast, easy cleaning with high-velocity flush and quick disassembly for hand cleaning
• Consistent material application and thickness control
• Reduced material waste and improved surface quality
• Similar functionality to air-operated sprayers for ease of use

Applications:
Industrial pumping of abrasive, heavily filled materials such as cementitious mortars, epoxy mortars, non-skid coatings, and polymers with fillers. Ideal for coating contractors seeking to replace hand troweling with a more efficient, consistent, and less wasteful application method.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, and maintains warranty coverage.
• Ensure proper air supply for pneumatic operation
• Follow manufacturer guidelines for hose and applicator connections
• Regularly inspect and clean the pump and hoses to prevent buildup of heavy materials
• Use recommended cleaning procedures, including high-velocity flush and, if necessary, hand cleaning after disassembly
