The GRACO 19X091 SOLOTECH ST23 PUMP is a peristaltic hose pump designed for industrial metering and transfer applications. It features a robust construction with engineered hose and stainless steel components, intended for reliable, leak-free pumping of caustic, abrasive, or sensitive materials within GRACO equipment.

Key Features:

• Peristaltic Hose Pump
• ST23, 23 mm hose inner diameter
• Engineered hose, stainless steel barb, one-piece center section
• Maximum flow rate: 17 lpm (varies by model and configuration; some sources specify up to 17.98 lpm at 94 rpm for similar models)
• Maximum fluid working pressure: 9 bar (0.9 MPa, 125 psi)
• Designed for use with GRACO industrial equipment and compatible with various motor types (AC or BLDC)
• CE (for similar models)
• Single oversized roller 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
• One hose compression per revolution reduces wear
• Leak-free design due to one-piece center section

Applications:
Industrial metering and transfer of caustic, abrasive, or sensitive materials; suitable for mining, agriculture, and other heavy-duty environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
• Ensure proper alignment and secure mounting of the pump
• Use recommended hoses and fittings for best performance
• Follow manufacturer guidelines for motor selection and electrical connections
• Regularly inspect and replace hoses as needed to prevent leaks and maintain efficiency
