The GRACO 19Y021 SOLOTECH ST26 PUMP is a peristaltic (hose) pump designed for industrial fluid transfer. It features a stainless steel connection and is engineered for reliable, low-maintenance operation in demanding environments. Its primary function is to move fluids efficiently and safely, minimizing wear and maintenance needs.

Key Features:

• Peristaltic (hose) pump
• ST26, 1 in. hose diameter
• Stainless steel connection, cast aluminum housing
• Maximum flow rate: 39 gpm (148 lpm) for standard models; some configurations may have lower flow rates (e.g., 10.18 gpm for low-speed AC motor models)
• Maximum discharge pressure: 70–125 psi (4.8–8.6 bar, 0.48–0.86 MPa) depending on configuration
• Industrial fluid transfer applications; compatible with various motor types (AC, BLDC)
• CE (for some models)
• Single oversized roller compresses hose through 360° rotation for improved hose life
• No valves, seals, or glands—inexpensive to maintain
• Reversible operation for emptying lines or clearing blockages
• Large sight window for easy access and visibility of internal parts
• Adjustable feet for improved mounting flexibility
• Metallic roller with bearings for constant compression and flow
• Extended hose life due to only one compression per revolution

Applications:
Industrial fluid transfer, including mining, agriculture, and manufacturing. Suitable for handling abrasive, viscous, or shear-sensitive fluids.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment and secure mounting using adjustable feet
• Verify hose and connection compatibility before installation
• Follow manufacturer guidelines for motor and electrical connections
• Regularly inspect hose and roller for wear and replace as needed
• Routine inspection of hose and internal components
• Use only recommended replacement hoses and parts
• Keep pump clean and free from debris
• Monitor for leaks or unusual noises during operation
