Graco SoloTech Peristaltic Hose Pump
SoloTech single-roller peristaltic hose pump. Single-roller design = 360-degree hose compression, only one compression per revolution = longer hose life than multi-roller designs.
SoloTech Single-Roller Peristaltic Hose Pump
How does the Graco SoloTech work? Its single roller produces 360-degree hose compression with only one compression per revolution. The process fluid remains inside the selected hose and barb fittings rather than contacting the casing or roller.
360-Degree Hose Compression
The single-roller design compresses the hose through the pumping cycle.
Fluid Isolated in the Hose
The hose and selected barb fittings form the wetted path. The casing and roller remain isolated from the process fluid.
One Compression Per Revolution
Only one compression per revolution provides longer hose life than multi-roller designs.
Graco SoloTech Key Specifications
The following values are manufacturer-stated specifications from the approved SoloTech reference sheet. Final model selection still depends on the exact configuration and duty.
SoloTech Hose and Barb Materials
Hose and barb selection determines the process-fluid contact path. Compatibility must be verified against the exact chemical, concentration, temperature, solids, and operating conditions.
| Hose Material | Color | Temperature Information |
|---|---|---|
| Natural Rubber | Black | Verify against the exact application |
| CSM / Chlorosulfonated PE | Orange | Up to 250°F |
| EPDM | Blue | Up to 220°F |
| NBR / Nitrile | Yellow | Up to 250°F |
| Food Grade Nitrile | White | Designated food-grade configurations only |
| Barb Materials | Selection Requirement |
|---|---|
| Stainless Steel | Verify chemical and process compatibility |
| PVDF | Verify chemical and process compatibility |
| Hastelloy | Verify chemical and process compatibility |
What Touches the Process Fluid?
Wetted components are the hose and selected barb fittings. The process fluid is isolated from the casing and roller. There is no dynamic process shaft seal and there are no check valves.
Graco SoloTech Motor Options

SoloTech Certifications and Conformity
Certification language must stay tied to the component or designated configuration to which it applies.
UL508C and CE
UL508C and CE conformity apply to the Graco Motor Control component specifically, not automatically to every complete pump configuration.
ATEX
ATEX is available on select SoloTech models.
FDA CFR Title 21
Food-grade status applies to designated food-grade configurations only.
Problems the SoloTech Peristaltic Hose Pump Solves
SoloTech is designed for duties where fluid isolation, controlled pumping, reversible operation, and suction capability matter.
Caustic, Abrasive & Shear-Sensitive Pumping
The hose-based fluid path can be evaluated for caustic, abrasive, and shear-sensitive fluids when the selected hose and complete operating duty are verified.
Chemical Metering
Variable-speed configurations support chemical metering across the stated model and flow range.
Selected Slurry Transfer
Final solids size, concentration, and hardness limits depend on hose ID and the specific model. Verify those limits before specification.
Reversible, Self-Priming Operation
Reversible flow supports line-direction changes, while published wet and dry suction lift is approximately 31–33 ft.
