Graco SoloTech Peristaltic Hose Pump
Single-roller design — 360-degree hose compression, one compression per revolution — for longer hose life than multi-roller peristaltic pumps handling caustic, abrasive, or shear-sensitive fluids.

How does the SoloTech work? Its single roller produces 360-degree hose compression with only one compression per revolution. The process fluid stays 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 full pumping cycle, rather than the multiple partial compressions a multi-roller pump applies.
Fluid Isolated in the Hose
The hose and selected barb fittings form the entire wetted path. The casing and roller stay isolated from the process fluid — no dynamic process shaft seal, no check valves.
One Compression Per Revolution
Only one compression per revolution reduces cyclic hose stress, which is the source of SoloTech's longer hose life vs. conventional multi-roller peristaltic designs.
Key Specifications
Values below are manufacturer-stated. Final model selection still depends on the exact chemistry, concentration, and duty cycle — request a spec review before ordering.
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 — see the LibertyCES Chemical Compatibility Chart as a starting reference.
| Hose Material | Temperature Information |
|---|---|
| Natural Rubber | Verify against the exact application |
| CSM / Chlorosulfonated PE | Up to 250°F |
| EPDM | Up to 220°F |
| NBR / Nitrile | Up to 250°F |
| Food Grade Nitrile | Designated food-grade configurations only |
Motor Options
AC Gearmotors
AC gearmotor options from 0.25–3.0 HP.
IP66BLDC with Graco Motor Control
Brushless DC configuration paired with the Graco Motor Control.
Type 4X / IP66Gearbox-Only

Configuration dependentCertifications and Conformity
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
Caustic, Abrasive & Shear-Sensitive Pumping
The hose-based fluid path can be evaluated for caustic, abrasive, and shear-sensitive fluids once 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, with published wet and dry suction lift around 31–33 ft.
Selection boundary: The final pump model, hose, barb, drive, certifications, solids limits, and operating range must be verified for the exact application before specification.

Frequently Asked Questions
What is the maximum flow rate of a Graco SoloTech peristaltic pump?
Approximately 18 GPM at the top of the range, on the largest SoloTech 30/32 models at 125 psi max working pressure. Smaller sizes (6, 10, 23, 25, 26) cover the range down to fractions of a GPM for precision dosing.
What touches the process fluid on a SoloTech pump?
Only the hose and the selected barb fittings. The casing and roller are isolated from the process fluid — there is no dynamic process shaft seal and no check valves.
Does a certification like ATEX or FDA apply to the whole pump?
Not automatically. UL508C/CE apply to the Graco Motor Control component specifically, ATEX is available on select models only, and FDA CFR Title 21 food-grade status applies to designated food-grade configurations only — always confirm the certification against the exact configuration being ordered.
Can a SoloTech pump run dry or self-prime?
Yes — SoloTech is self-priming and reversible, can move abrasive or viscous fluids, clear lines, and run dry safely without damaging the pump.
