Stainless steel (SS)
Compatible with GRACO equipment requiring peristaltic pump solutions
Single roller design compresses hose through 360 degrees for longer hose life
No valves, seals, or glands—inexpensive to maintain
Reversible operation for emptying lines or clearing blockages
Engineered for handling tough, abrasive, or sensitive materials
Extended hose life due to only one hose compression per revolution
Applications: Used for metering or transferring caustic, abrasive, or sensitive fluids in industrial settings such as lubrication, chemical processing, and maintenance applications.
Installation Notes:
Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
Install the flangehead bolts onto the front cover as specified in the manual
Place the gasket on the front cover over the screws
Install the front cover on the pump housing
Torque the screws oppositely and evenly to the recommended torque (for similar models, torque is typically 7–9 ft-lb for smaller models, but always check the specific manual for ST6-HAC-CS-SS-A1-A1-0)
Ensure all connections are secure and leak-free before operation
Regularly inspect the hose for wear and replace as needed
