Graco 26A304 T3 Supply Pump (Stainless Steel): 3:1 Fluid to Air Ratio

Graco 26A304 T3 Supply Pump — Stainless 3:1 for Reliable Reactor Feed

The Graco 26A304 T3 is a stainless-steel, 3:1 supply (transfer) pump designed to move A & B materials directly from 55-gal drums to plural-component proportioners. Built on a proven Merkur air motor with the popular T2 lower, the T3 platform delivers the required fluid pressure with less air, runs noticeably quieter, and sits lower above the drum for easier handling inside spray rigs—ideal for spray foam, polyurea, and protective-coatings workflows.

Where it fits & how it’s used: Mount to a standard drum bung and plumb to Graco Reactor units or similar proportioners for steady drum-to-machine delivery, day-tank supply, or recirculation loops. Typical performance is up to ~4.5 GPM (material-dependent) with 100 psi max air and 315 psi max fluid—the sweet spot for maintaining consistent inlet pressure and fewer alarms on high-uptime rigs and shop lines.

Key Features & Benefits

• 3:1 fluid-to-air ratio for efficient pressure with reduced air use
• Stainless wetted parts for corrosion resistance and long service life
• Up to ~4.5 GPM continuous output (application dependent)
• Max air 100 psi; max fluid 315 psi
• Shorter height above drum (≈3.7 in) for easier in-rig removal
