Benefits of Peristaltic Pump Technology

Unlike conventional pumps that rely on seals, valves, or diaphragms, the SoloTech ST23 uses a hose compression design that minimizes maintenance requirements and reduces the risk of leaks. Only the hose contacts the pumped material, making the pump suitable for handling aggressive chemicals, abrasive slurries, and sensitive fluids.

  • Handles abrasive and solids-laden fluids efficiently
  • Suitable for corrosive and chemical processing applications
  • Gentle pumping action for shear-sensitive products
  • Self-priming operation
  • Dry-run capable for short periods
  • Reversible flow capability for line clearing and product recovery
  • Low maintenance design with fewer wear components

Common Applications

The Graco 19X086 SoloTech ST23 Pump is widely used across industries where reliable fluid transfer is critical. Typical applications include chemical processing, wastewater treatment, paint manufacturing, industrial coatings, mining operations, adhesive handling, and general process fluid transfer.
