The Pump That Doesn't Quit
One roller. No seals. No babysitting. SoloTech keeps flow moving where every other pump taps out.
Single-roller design — simpler, tougher, fewer wear points.
No mechanical seals. No seal kits. No seat leaks.
4× expected life — extended service windows.
"Graco's best-kept secret. It's never failed us — only solved the hardest problems." — James Riggins

Frequently Asked Questions
What flow range do Graco SoloTech peristaltic pumps cover?
LibertyCES specs the full SoloTech lineup from 6mm to 32mm hose sizes, covering 0.2–41 GPM (roughly 0.76–155.2 LPM) across the ST10 through ST32 model series.
Why does SoloTech last longer than a standard peristaltic pump?
Its single-roller design applies one compression per revolution instead of multiple, delivering roughly 4× the hose life of conventional multi-roller peristaltic pumps, with seal-less construction eliminating seal-kit maintenance entirely.
Can SoloTech pumps run dry or self-prime?
Yes. SoloTech pumps are self-priming and reversible, can move abrasive or viscous fluids, clear lines, and run dry safely without damaging the pump.
What is the maximum pressure and temperature rating for SoloTech?
Up to 125 psi (0.9 MPa / 9 bar) and up to 176°F (80°C), hose-material dependent — enough headroom for thick slurries, polymers, and caustics without cavitation.
