The GRACO 19X189 SOLOTECH ST30 PUMP is a peristaltic hose pump designed for industrial applications. It features a robust construction with a single oversized roller that compresses a low-friction hose through a full 360 degrees of rotation, ensuring reliable and gentle fluid transfer. The pump is intended for use in demanding environments where precise, low-pulsation flow and minimal maintenance are required.

Key Features:

• Peristaltic Hose Pump
• SOLOTECH ST30
• Aluminum or Stainless Steel center section (model dependent), Stainless Steel connections
• Maximum flow rate up to 39 gpm (148 lpm) for standard models; some variants may differ (e.g., up to 59.8 lpm for certain configurations)
• Maximum discharge pressure up to 70 psi (4.8 bar, 0.48 MPa) for standard models; some configurations may handle up to 125 psi (8.6 bar, 0.86 MPa) or 0.9 MPa (9 bar)
• Designed for integration with GRACO industrial equipment and compatible with various motor types (AC or BLDC)
• Single oversized roller for gentle, low-pulsation flow
• Low-friction hose for extended service life
• Robust construction for demanding environments
• Easy maintenance and hose replacement
• Reliable, continuous duty cycle

Applications:
Industrial fluid transfer, chemical processing, mining, agriculture, and other applications requiring precise, low-maintenance pumping solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting of the pump
• Use recommended hose and connection types for best results
• Follow manufacturer guidelines for motor and gear reducer installation
• Regularly inspect and replace the hose as needed to maintain performance
• Periodically check hose condition and replace if worn
• Lubricate moving parts as recommended
• Monitor for leaks and unusual noise
• Keep pump and surrounding area clean to prevent contamination
