Applications

The Graco 19X137 SoloTech ST26 Pump is commonly used in industries where reliable fluid transfer is essential. Its peristaltic design makes it ideal for handling slurries, chemicals, wastewater, additives, viscous liquids, and other challenging media while minimizing contamination risks and maintenance requirements.

Technical Overview

As part of the SoloTech product family, this pump utilizes a robust hose compression mechanism that creates a consistent flow while keeping the pumped media contained within the hose. This design significantly reduces exposure of internal pump components to the process fluid, improving service life and operational reliability.

Frequently Asked Questions

The pump is used for transferring abrasive, viscous, chemical, and shear-sensitive fluids in industrial processing, water treatment, chemical handling, and OEM fluid transfer systems.

No. The MN configuration includes a medium-speed NEMA gear reducer but is supplied without a motor.

This configuration is equipped with a natural rubber (NR) hose, which is suitable for a variety of industrial fluid transfer applications.

No. The SoloTech ST26 is an industrial peristaltic hose pump designed for fluid handling systems and OEM equipment rather than paint sprayers.

Peristaltic pumps provide low-maintenance operation, excellent chemical compatibility, gentle product handling, dry-run capability, and reduced risk of contamination because the fluid remains contained within the hose.
