The GRACO 19C646 SoloTech ST6 Pump is a peristaltic hose pump designed for heavy-duty fluid transfer and metering applications. It features a stainless steel construction for durability and is engineered to handle caustic, abrasive, or sensitive materials. This pump is intended for use within GRACO equipment for reliable and efficient fluid management in demanding industrial environments.

Key Features:

• Peristaltic Hose Pump
• ST6
• Stainless Steel
• Designed for integration with GRACO fluid transfer and metering systems
• Single roller compresses engineered hose through 360 degrees for longer hose life
• No valves, seals, or glands—inexpensive to maintain
• Reversible operation for emptying lines or clearing blockages
• Extended hose life due to only one hose compression per revolution
• Engineered for lasting, heavy-duty performance

Applications:
Ideal for metering or transfer of caustic, abrasive, or sensitive materials in industrial, municipal, and process applications. Suitable for use in mining, agriculture, and other sectors requiring robust fluid handling solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and safety of the equipment.
• Level the pump as required, using shims
• Initially tighten anchor bolts one eighth of a turn with a wrench; do not fully tighten until all piping is connected
• Always run the pump with a control (VFD for AC models or GRACO Motor Control for BLDC models)
• Securely mount the controller
• For pumps with BLDC motors, use the provided mounting tabs
• Lubricate the pump with genuine GRACO hose lubricant to reduce risk of fire or explosion from static sparking or chemical incompatibility
