The GRACO ToughTek M680a Bare Piston Pump System is a pneumatic piston pump package designed for industrial applications, constructed primarily from stainless steel. It is intended for pumping heavily filled cementitious materials, offering reliable and consistent material transfer with reduced wear on pump components due to low-pressure operation.

Key Features:

• Pneumatic Piston Pump Package
• M680a
• Stainless Steel
• 10.88 GPM
• Maximum Working Pressure: 1000 psi (7 MPa, 70 bar, 7000 kPa)
• Cementitious Material
• Low pressure pumping (200–500 psi/13.7–34.5 bar) reduces wear on pump lower
• Flex Hose Applicator for ease of use and reduced material waste
• Durable stainless steel construction for longevity
• Consistent finish and less material waste compared to manual application
• Industrial-grade reliability and ease of maintenance

Applications:
Industrial pumping of heavily filled cementitious materials such as mortars and grouts.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure all connections are secure and compatible with NPT threads (1-inch female outlet, male inlet)
• Follow manufacturer guidelines for pneumatic system setup and pressure regulation
• Regularly inspect and maintain pump components to prevent clogging and wear
• Use appropriate safety measures when handling pressurized systems
• Consult the equipment manual for detailed installation and maintenance procedures
• Use only compatible materials as specified by GRACO
• Schedule routine maintenance to ensure long-term reliability
